This one-volune collection, consisting of three manuscripts bound together, was previously named "Names of various trees, shrubs, and plants in the language of the Lennape [sic], 1840" after one of the manuscripts in it. It consists of Nottoway terms, organized according to a variety of categories; a Lenape (Delaware) word list relating to English botanical terms, along with Latin terms; and an English-Algonquian-Lenape comparative vocabulary.
