Gleason and Tate, Tyler-Duida Expedition, 1928-1929, [numbers 1-998].

Résumé du livre

This field book documents botanical collecting by George Henry Hamilton Tate in Venezuela on the Tyler-Duida Expedition of 1928-1929, sponsored by the American Museum of Natural History. It consists of a list of specimen numbers 1-998. Entries list plant name (mostly by family only, not the full name), location, date, and descriptive notes on the plant and/or collection location. Some descriptions have small drawings, and pages 35 and 37 have plant material glued to the page. The first page has a list of collecting localities, all on or around Mt. Duida, and pages 72-74 have an index to the collection by plant family. There is a list of the same specimen numbers in Field notes Vol. 92 with full plant name determinations. A pocket contains a letter from Tate to Gleason dated July 18, 1929 with an itinerary of the botanical collecting on the Tyler-Duida Expedition; a handwritten list of missing numbers; and two typewritten pages listing specimens. The Tyler-Duida expedition was a major expedition of the American Museum of Natural History to Cerro Duida in 1928-1929, led by George Henry Hamilton Tate. It was the first to reach the mountain's summit plateau and the first to climb a tepui of the Venezuelan Amazon. Although primarily a zoological expedition, much plant material was collected. These herbarium collections were studied extensively by Henry Gleason, who formally described many of the mountain's plant species in a series of papers published in 1931.
