HITCHCOCK AND CHASE—GRASSES OF THE WEST INDIES. 263 
from Jamaica, most fully represented in the New York Botanical 
Garden Herbarium; those of Sintenis from Porto Rico, Eggers from 
_ St. Thomas, and Ricksecker from St. Croix; those of Duss from 
Martinique and Guadeloupe, the original set of which is at the New 
York Botanical Garden; those of Broadway from Tobago and Trini- 
dad; and also the recent collections made by Dr. N. L. Britton and 
other members of the staff of the New York Botanical Garden, who 
have visited nearly all parts of the West Indies. The herbarium of 
the Botanical Garden, Port of Spain, Trinidad, contains a large 
collection of Trinidad plants made by successive superintendents of 
the garden.’ This collection was examined by Mr. Hitchcock during 
his visit to Trinidad. 
The senior author first visited the West Indies in 1890. An ac- 
count of this trip was given in a paper entitled “ List of Plants Col- 
lected in the Bahamas, Jamaica, and Grand Cayman.” In 1906 he 
visited Cuba, collecting in the Provinces of Habana and Pinar del 
Rio. In 1912 he visited Jamaica, Trinidad, and Tobago. During 
this second visit to Jamaica Mr. Hitchcock was greatly aided by Mr. 
William Harris, Superintendent of Public Gardens, Hope Gardens. 
He was similarly aided in Trinidad by Mr. W. G. Freeman, Assistant 
Director of Agriculture, Port of Spain. Mr. W. E. Broadway, Su- 
perintendent of the Experiment Station at Scarborough, extended 
many courtesies to him while in Tobago. The junior author visited 
Porto Rico in 1918, where her work was greatly forwarded by Dr. 
F. L. Stevens, then Dean of the College of Agriculture, Mayaguez. 
The citation of synonymy is not complete; names based upon col- 
lections from elsewhere than the West Indies are usually not given 
unless they occur in some of the works on the West Indian flora. 
An attempt has been made to account for names based upon West 
Indian material, but only by an exhaustive search through literature 
can the synonymy be completed. 
The descriptions of the genera and species are usually merely diag- 
nostic and are intended to supplement the keys. 
Common names have been added in those cases where the grass is 
definitely known by an English name over a considerable area. To 
several Cuban species are appended vernacular names which were ob- 
tained in part from the Flora de Cuba®* and in part were communi- 
cated by Brother Leén‘ and by Professor Roig.
