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.

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

Identifying Woody Plants (Month 1)

/

The Identifying Woody Plants field class I am taking at Missouri State University has met 5 times. There have been two off-campus field trips that I’ve posted about previously: Springfield Botanical Gardens and Lovett Pinetum. The other sessions have included walks around the MSU campus identifying trees. Just as in the off-campus field trips, I’ve tried to get good pictures of the trees so that I can include them in my PowerPoint based ‘flashcards’ to help me learn all the woody plants presented in the class (even though I am not taking the class for credit).

In the first class, I tried using my cell phone…juggling it with my small notebook for note taking. It did not work so well; I only got reasonable pictures for three of the trees we encountered.

Black gum – Nyssaceae – Nyssa sylvatica

Buckeye – Sapindaceae – Aesculus

For the next campus walk – I used my small point-and-shoot camera and managed more pictures. I had front pockets for both the small notebook and the camera. It was a very hot/sunny day; I wore my fingerless gloves to keep my small notebook dry. I did not feel well during the later parts of the walk even though I was drinking plenty of water.

American Sycamore – Platanaceae – Platanus occidentalis

Yew – Taxaceae - Taxus

Flowering dogwood – Cornaceae – Cornus florida

Bald cypress – Cupressaceae – Taxodium distichum

Shortleaf pine – Pinaceae – Pinus echinata

American basswood – Malvaceae – Tilia americana

The third walk around campus was easier; I had my system for juggling the notebook and camera…and it wasn’t quite as hot. I also wore my hiking boots, so my feet did not hurt like they did on one previous campus walk. I am still not managing to photograph everything during the walk; for the ones I miss (i.e. not listed in this post) I glean photos from the class charts and/or web searches to populate my study Powerpoint.

Red Maple – Sapindaceae – Acer rubrum

Burning bush – Celastraceae – Euonymous alatus

Northern red oak – Fagaceae – Quercus rubra

Northern catalpa – Bignoniaceae – Catalpa speciosa

Yellow poplar – Magnoliaceae – Liriodendron tulipifera

True cedar – Pinaceae - Cedrus

Siberian elm – Ulmaceae – Ulmus pumila

Sweet gum – Altingaceae – Liquidambar styraciflua

Pin oak – Fagaceae – Quercus palustris

Honeylocust – Fabaceae – Gleditsia triacanthos

There is some memorization involved…but I am beginning to find that I remember the scientific names as well as the common names as I continue to study…adding new woody plants to the list each week. The class is living up to my expectations in helping me expand my identification skill of woody plants of Missouri.

Registering for a College Class

/

I registered for a class at Missouri State University last week – Identification of Woody Plants. It has been over 40 years since I did this last! Lots has changed in those years.

  • I didn’t need to go through an admissions process ahead of time or get transcripts sent because I am part of the cohort of people over 62 years old that can attend classes at much reduced cost (MSU 62). I called their office a week before the registration day to confirm. I also asked about the pre-req for the class I wanted to take; I had the pre-req in my long-ago college experience but without the transcript, how would they know? I was advised to email the instructor to get a waiver…which I did and they waived the pre-req for me.

  • The course catalog and schedule are all online now rather in paper/soft cover books. I knew that there were only 7 slots remaining in the course I wanted to take before I headed to registration.

  • The registration for the MSU 62 cohort was held the week before classes started which is later than I usually registered back in the 70s. I arrived just after they opened. The receptionist for the event handed me forms and sent me to tables/chairs to fill them out. The course I wanted to take was not on the paper version of a course list on the tables, so I was glad I had the numbers for it written down to enter in the appropriate places on the form. I also had the printed version of the email exchange with the instructor. I was so focused on the requirements for my degree 40 years ago…now I am just taking whatever interests me and not for credit.

  • When I finished the forms, I joined the queue in chairs waiting for advisors…and thoroughly enjoyed a donut while I waited. I don’t remember ever having food provided when I registered for college classes before!

  • The advisor got me admitted and registered very quickly. She discovered that I already had a number with the university (maybe because I had donated back in 2020).

  • After that I was routed to a second person that printed out my concise schedule and talked to me about setting up my computer accounts, books and parking permits. It appears that the only cost is going to be for the parking pass – quite a bargain even compared to the costs I had in the 1970s. In addition, the textbook for the class I am taking is listed as ‘optional’ so I am waiting to buy it until after I hear what the instructor says in the first session.

Less than an hour after I entered the building, I was walking back to the parking garage. Along the way I photographed the colorful school mascot (bear) at the corner of the building. I am looking forward to this course…not so different from the way I always looked forward to the fall during my education-intense years…but savoring that I won’t be taking any tests!
