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 Kico, 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. 1 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." 2 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 1913, 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 3 and in part were communi- 

 cated by Brother Leon 4 and by Professor Roig.
