This checklist is based on collections made for this project on numerous collecting trips but even then there are still many species that have not been documented to occur in the Preserve. Use the "Specimens" link in the banner for making searches for  specimens. This link will enable accessing collections of a specific collector, a given species, from a certain trail, gathered in June, etc. Specimen vouchers of the species inventoried are archived in the Steere Herbarium of The New York Botanical Garden.

Checklist by Plant Family

Our checklist is a list of species of flowering plants documented by herbarium specimens or, in the case of rare or very common species, by images. When a species name in the list is clicked on the specimens that represent the species are accessed. The  records include the scientific name, label data, images of the herbarium sheets, and field images. One of the ways that botanists learn the names of plants is to compare specimens of an unknown plant with collections in a herbarium. Let us assume that you encounter an oak tree that you do not recognize. There are lots of oak collections and many different species in large herbaria so it is time-consuming. In this case, the herbarium is a virtual herbarium, i.e.. you look at images of herbarium sheets and field images from a very limited area. In order to learn the name of the unknown oak, you compare the images of the four species we know to occur in the WLT Preserve.

Some plant  families have been placed in other families. For example, the Aceraceae are now part of the Sapindaceae, the Nyssaceae are moved to the Cornaceae, and Tiliaceae have been placed in  the Malvaceae. Consult Stevens (2001 onward) for information about family changes by the Angiosperm Phylogeny Group (APG). The APG website is listed in our Literature  page which is linked  to under "Resources." on this page. An easier way is to ask Google what family does the genus Acer belong to?

Checklist by Common Name

If you know the common name of a plant you can click on "Checklist by Common Name"  and all specimens of species with that common name will be accessed for you to compare with the plant you want to identify. 

Resources

Identification Aids. A series of Power Point presentations that show species with certain characters; for example, species of the skunk cabbage(Araceae) family that bloom in the spring and the species of  plants without chlorophyll are now available. 

Identification Keys (under construction). A series of electronic keys used for idetentifying certain groups of plants. A key to woody vines has been completed and a key to the trees of Preserve is being written.

Glossary. A botanical glossary illustrated with images.

Literature. A list of publications that help the user learn more about the plants of the Preserve.

Specimen collection video. An intern from the Taft School shows how she helped with establishiing the website.

Plant names. A PDF of a PowerPoint presentation about plant names. 

Leaf terminology. A PDF of a PowerPoint presentation about leaf characters that helps visitors learn the leaf terminology needed to  identify plants.

Flower terminology. A PDF Power Point presentation about flower characters that helps visitors learn the flower terminology needed to  identify plants.
