Marchantiaceae.

The Lucien Marcus Underwood collection consists of correspondence, research papers, manuscripts, lecture notes, and artwork covering the latter part of his botanical career, including that with the NYBG. The research papers include specimen catalogues and lists, some of which relate to the Underwood collection of the NYBG herbarium. Underwood’s field notebooks are separated from the present collection and are located in the Collectors’ Field Notebook collection.
