Identifying Woody Plants (Month 2)

/

The Identifying Woody Plants field class I am taking at Missouri State University has met 5 more times since my last post about the field sessions on the campus.

I am continuing to take pictures of items in the classroom before class:

An opened Maclura pomifera (Osage orange) fruit

Some Quercus macrocarpa (Bur oak) acorns

An herbarium page showing Tilia americana (American Basswood) fruit which we have seen in the field, but my pictures were not very good.

Cuttings from two plants were brought in and we were asked to ID them based on our notes – with the hint that the first one had milky sap (hard to see since it had been cut):

Morus alba (white mulberry) – a non-native that is frequently seen as a ‘weed’ tree and Vitis (grape).

Recently the walk from the parking lot to the classroom building has been full of late blooming pollinator plants and fall foliage.

The one session where we stayed on campus added some new trees to our list:

Quercus bicolor (Swamp white oak)

Sassafras albidum (Sassafras)

Carya ovata (Shagbark hickory)

Quercus lyrata (Overcup oak)

We also saw some review trees and I got better pictures of Celtis occidentalis bark (Rough hackberry)

And some add odd growth of a Liriodendron tulipifera (tulip/yellow poplar). The trunk of the tree was growing at a slant rather than straight upward and it had small branches coming out relatively close the ground.

The hikes on campus and further afield have been more pleasant this past month because the temperatures have been cooler. There have been no rainy days in the field either!

Busiek State Forest and Wildlife Area

/

A sunny fall day…the Identifying Woody Plants Class spent a couple of hours at Busiek State Forest and Wildlife Area – adding 9 more woody plants to our list and seeing others that were already on the list and we practised our ID skills for them; there are now 78 woody plants that we should recognize and be able to supply the common name, family, and scientific name!

We encountered an Osage Orange (Maclura pomifera) – a tree we’d seen in previous classes - that had leaves that hadn’t fallen before the first hard frost. All of us began to realize how changed identification was going to be without leaves on the trees!

The first new one was Box Elder (Acer negundo) – the only maple with compound leaves. ID is helped by its green branches.

The second new tree was Spicebush (Lindera benzoin) – still with leaves and one I had seen recently in a Missouri Master Naturalist field trip. The picture I took was of a male but there were female trees with red fruit that we saw at Busiek.

 American Sycamores (Platanus occidentalis) were growing along the dry creek bed…another tree that we reviewed. The very large leaves were still mostly on the tree.

The third new tree was the Carolina willow (Salix caroliniana)…also growing close the dry creek bed. Its leaves are a little bigger that the Black Willow’s…and the stipules tend to stay on rather than falling off. It still had leaves…everyone realized it was a willow of some kind.

I couldn’t resist taking some pictures from the dried creek bed. The fall color is a bit muted this year because it has been so dry here. I noticed some wasp apartments on one of the bridge support columns.

Another review tree – the honey locust (Gleditsia triacanthus) – and I finally got some pictures of thorns. I also picked up a seed pod to put in the tree educational trunk I am creating for Missouri Master Naturalist.

The fourth new tree was the Chinkapin oak (Quercus meuhlenbergii). I didn’t get any good pictures of it!

The same was true of the fifth new plant – a vine: Greenbrier (Smilax). Supposedly it might be something that will be easier to see and ID in the winter because the stems stay green….and the thorns would be on the vine too – to mistaking it for a grape (Vitis).

Smooth sumac (Rhus glabra) was the sixth addition for the day. The plants did not have the distinctive seed heads because they tend to get cut down frequently so that they don’t take over the area where they are growing.

Persimmon (Diospyros virginiana) was our seventh new plant. The fruits looked beautiful, but no one was willing to try them quite yet. I am glad I have planted some in my yard and hope to enjoy them at perfect ripeness in the future.

The eighth new plant was a native woody grass/bamboo: giant cane (Arundinaria gigantea).

The ninth (and last) new plant for the day was an Eastern Cottonwood (Populus deltoides). Most of the leaves were gone…but the one we looked at was a huge tree with deeply grooved bark and buds ready to go for next spring.

It was a good walk and a transition point for the way we will begin to identify trees by characteristics other than their leaves.

Lake Springfield with Identifying Woody Plants Class

/

This past week the field class I am taking through Missouri State University added new woody plants to our list from a walk near the  Lake Springfield boathouse. I tried to take pictures of most of the new woody plants for this week…and a few from previous weeks:

Marshmallow – Hibiscus – Malvaceae (seed pods)

Green ash – Fraxinus pennsylvanica – Oleaceae (leaves and diamond shapes in the bark)

Black willow – Salix nigra – Salicaceae (leaves/twig)

Osage orange - Maclura pomifera – Moraceae (fruit…and I now have a fruit I am attempting to dry)

Honey locust - Gledistia tricanthos – Fabaceae (tree with drying seed pods)

Privet (non-native) - Ligustrum – Oleaceae (leave with blue fruit)

American hophornbeam – Ostrya virginiana – Betulaceae (leaves with thin, strong twigs)

Post oak – Quercus stellata – Fagaceae (rounded lobed leaves)

Bur oak - Quercus macrocarpa – Fagaceae (leaves…in the red oak group…I also picked up an acorn!)

It was an interesting afternoon…but I was tired afterward.

Phelps Grove Park

/

Last week the Identifying Woody Plants class walked to Phelps Grove Park to add more trees to our list. I used my point-and-shoot (Canon Powershot SX730 HS) to capture some features of the additional trees (plus some trees already on our list). The temperaature was in the 70s…perfect for the hike…but the leaves are beginning to fall on many of the trees. Identification will get harder.

Serviceberry – Amelanchier arborea – Rosaceae: stripped bark, multiple trunks, small trees, two toned pointy buds, leaves simple and alternate

Crabapple – Malus – Rosaceae: pome without grit, twigs hairy, leaves (lobed, simple, entire)

Hawthorne – Crataegus – Rosaceae: thorns, pome, leaves round, bark pealing and patchy, the one we saw was infested with apple cedar rust (i.e. not a healthy tree)

Fig (just for interest…not added to list)

Flowering dogwood (not new) – Cornus florida - Cornaceae

White oak – Quercus alba – Fagaceae: leaves (rounded lobes, smooth, lighter underneath), acorns dark with bumpy cups and often sprout in fall

Hemlock (not new) – Tsuga canadensis - Pinaceae

Black cherry – Prunus serotina – Rosaceae: observed bark…branches too high to see more

Osage orange – Maclura pomifera – Moraceae: bark shaggy and orange in parts, leaves (tapering tip, entire, alternate, simple, size varies), the one we saw was male so no fruit

Red mulberry  - Morus rubra – Moraceae: milky sap, leaves (toothed, shiny, falling)


Shortleaf pine (note new) – Pinus echinate – Pinaceae

Hackberry – Celtis occidentalis – Cannabaceae: drupe that can taste like a dry raisin, leaves (3 veins, asymmetric, rough), the one we saw had galls, bark rough and gray, large tree

Shingle oak – Quercus imbricaria – Fagaceae: acorn small, leaves (no lobes, long and narrow, soft hair underneath), multiple buds at tend of twigs, bark grayish

Gleanings of the Week Ending August 10, 2024

/

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Versailles’s Hidden Scientific Legacy to Surface in a Major U.K. Exhibition - The five-mile-squared grounds were mapped out by geometricians and astronomers; keeping the 14,000 fountains bubbling further required developing an unprecedented hydraulic engineering system. AND… Giovanni Domenico Cassini, who headed the Paris Observatory, turned skyward, mapping the moon with a precision that wouldn’t be matched until the late 19th century. AND… Hundreds gathered in the courtyard of Versailles to watch the flight of a hot-air balloon, agronomists developed a hardier potato capable of feeding the masses, and an inoculation against smallpox was discovered.

Air conditioning causes around 3% of greenhouse gas emissions. How will this change in the future? – The article concludes: “Rather than lamenting air conditioning's impact on energy use, we need to accept that demand for cooling will increase, work on making it affordable for those who need it most, and build efficient solutions that ensure electricity grids worldwide can cope.”

Ancient Rome’s Appian Way Is Now a UNESCO World Heritage Site - Rome’s Appian Way, an ancient highway dating to the fourth century B.C.E., has been declared a UNESCO World Heritage site.

Could the shingles vaccine lower your risk of dementia? - The idea that vaccination against viral infection can lower the risk of dementia has been around for more than two decades. Associations have been observed between vaccines, such as those for diphtheria, tetanus, polio and influenza, and subsequent dementia risk. It may be the resulting lack of viral infection creating this effect. We need more research exploring in greater detail how infections are linked with dementia. This will help us understand the root causes of dementia and design potential therapies.

Chickasaw National Recreation Area's Monkey Tree Needs Some TLC - An Osage orange tree estimated to be about 130 years old with three thick spreading trunks that generations of children have played on.

Divers Discover Mesmerizing Roman Mosaic Beneath the Sea – Near Naples…a villa in a city known as the Las Vegas of the Roman Empire…now under water.

Healthy diet with less sugar is linked to younger biological age – The correlations between a diet that is rich in vitamins and minerals, especially one without much added sugar, and having a younger biological age at the cellular level.

Agriculture: Less productive yet more stable pastures - Grassland optimized for high yield responds much more sensitively to periods of drought than less intensively used meadows and pastures.

Anne Boleyn’s Childhood Home Is Restored to Its Tudor Glory – The interiors of rooms restored to the style they had during Anne Boleyn’s time.

Forest carbon storage has declined across much of the Western U.S., likely due to drought and fire – Forests in some parts of the world, like the American West, probably do not have the potential to help curb climate change.

Zooming – November 2022

/

18 images in the slide show for November – less skewed toward botanical subjects than recent months. Outings to Hagerman National Wildlife Refuge, Springfield Conservation Nature Center and Josey Ranch Lake increased my opportunity to photograph wildlife. It was good to see winter and migrating birds…more of those in coming months (probably).

Enjoy the November slide show!

Ritter Springs

/

Ritter Springs is a park near Springfield MO – north of the city in a rural area. It was our first visit to the park (one of our exploratory day trips this fall). There is a one lane paved road a short distance into the park then a gravel parking lot. A gate blocked the gravel road down to a pavilion; near the gate there was a map of the park and its connections to other nearby parks via trails.  

The park would have been a lot more scenic a few weeks earlier before most of the leaves fell. When we were there, drives of leaves accumulated everywhere…filling any low areas.

Even so we enjoyed our walk through the woods along the road and on mowed trails – looking for photo opportunities. I spotted shelf fungus that were bright spots in the fallen leaves,

A buckeye butterfly in a sunny spot,

The torn end of a recently fallen branch,

Some red leaves still on a young oak…protected from the wind by the bigger trees,

And a tree top full of cones.

But probably the tree I got most excited about was the Osage Orange. The tree had a very limited range in pre-colonial North America but has been planted by settlers as a hedge where its thorns deterred free-range livestock from vegetable gardens and corn fields. It also has historical significance in plains states where is was widely planted in rows for windbreaks. This time of year it is easier to identify the trees with their huge fruits….or simply looking up after seeing one of the greenish orbs on the ground. There are a lot more of the trees in Missouri than in Maryland!

I took a closer look at one of the fruits.

Next time…we’ll go further into the park…maybe even all the way down to the Little Sac River!

Springfield Botanical Garden – July 2022 (1)

/

The Springfield Botanical Garden is already one of my favorite places to walk around….easily taking the place of Brookside Gardens in Maryland. We parked near the rose garden. The roses were looking a little challenged by the summer heat but there were plenty of summer flowers to enjoy: cone flowers, zinnias, sunflowers (to name a few).

The hosta garden is always a cool and damp oasis. We arrived before 8 AM….before the heat of the day. I enjoyed photographing the flowers and leaves with water droplets on them.

There was one caladium leaf that had a shape like butterfly wings!

The lilies were still blooming profusely (see the June post for earlier in their bloom period). I took very zoomed images to avoid spent blooms that are part of the scene this month. It seemed that mesh had been put around more of the beds…maybe deer have become a problem.

I hadn’t noticed the Osage orange tree near one of the pollinator gardens before. It is full of fruit now. It is an interesting tree….without an efficient means of propagation without human assistance. Its seed dispersal evidently was via extinct megafauna (giant ground sloth, mammoth, mastodon, etc.). But – it was widely used for fencing/wind breaks by settlers and has been planted in all 48 contiguous states of the US and in southeastern Canada. It is not a rare tree even though it could become so without continued attention.

Stay tuned…in a few days I’ll post about the animal life I noticed in the garden this month.

Winter Tree Identification – Part 2

/

Continuing from yesterday -

Seeds that help with identification include tulip poplar (the pods stay on the trees releasing the seeds during the winter breezes to clog up any nearby gutters!),

seed tulip poplar.jpg

Osage orange (that fall to the ground and are only moved around my people these days…they were planted for fence rows after the dust bowl because they are hardy, and the seed balls are easily broken apart and planted),

osage orange.jpg

Sweet gum (the spikey seeds are a hazard in suburban yards and drive ways), and

sweet gum.jpg
black walnut1.jpg

Black walnuts (there are always nuts under the tree but the squirrels may carry then a little further away so look at the shape of the tree too).

Of course – there are trees that are not as easy to identify. That’s why I carry a small book – Winter Tree Finder – when I am hiking in the winter and looking at trees. I found mine at a used book sale, but they are available new from Amazon as well.

December on the Trolley Trail

/

The Howard County Conservancy organized a winter hike for its volunteers last week on the Trolley Trail (Trolley Trail #9 near Ellicott City/Benjamin Banneker Historical Park and Museum). We were celebrating the end of another fall field trip season. About 40 people met in the Banneker parking lot and headed out.

2018 12 IMG_0046.jpg

The connecting trail from Banneker to the Trolley Trail was through the forest and very muddy. There was an Osage orange tree that had dropped its fruit recently. Most of the fruit look pristine. When I got home, I did some research and discovered that the fruit is not eaten except sometimes by squirrels. One theory is that the fruit was eaten by large mammals that are now extinct (ground sloth, mammoth, mastodon) and that these animals would have spread the seed. Now the tree is propagated by people for its wood and as windbreaks.

We headed north on the Trolley Trail first. I didn’t take many pictures because I was so busy trying to keep up with the group. It was the same the last time I was on the Trolley Trail in 2015 with my Master Naturalist class (posted about it here).

There was some stream restoration (and maybe something else since there is infrastructure like sewer lines in the streambed) that was active next to the trail.  The stream did look more scoured than the last time we were in the area.

2018 12 IMG_0064.jpg

We reached the end of the trail at the north and retraced our steps…passing the trails to Banneker to continue south on the Trolley Trail.

We got to the part of the trail that was damaged in the last flood. Repair work was not complete, so we stopped before getting down to Ellicott City; I turned around and took a picture back along the trail. The asphalt of the trail was damaged by the flood; the asphalt edges were uneven, and pieces were missing.

There were bright green Christmas fens on the cliff to the right

2018 12 IMG_0074.jpg

A little further back up the hill, winter trees looked good against the sky. It’s easy to pick out the sycamores this time of year.

2018 12 IMG_0081.jpg

A waterfall was scenic rather than roaring. I thought more about what it must have been like during the flood to sweep away asphalt a little further down.

2018 12 IMG_0085.jpg

We’ve gotten so much rain this fall/early winter that the moss is thick and bright green – like a carpet.

We made the muddy trek back up to Banneker to retrieve our cars…and head for lunch with healthy appetites.
