kK. Broadway (cf. Orch. Rev. 48 (1985) 354). In the 
1920’s, Broadway published in the Orchid Review a series 
of papers on his discoveries. Many of the rare species, 
found on the islands for the first time, or re-collected after 
a lapse of many years, were briefly discussed, and valua- 
ble ecological and cultural notes were included for some 
of the species. It is unfortunate that Broadway never 
cited herbarium specimens to authenticate his discoveries. 
The Orchid Herbarium of Oakes Ames, where most of 
Broadway’s later collections were determined, counts 
itself fortunate in having a rather complete set of Broad- 
way s material. A number of the Broadway collections 
which established new records in plant distribution, but 
which were not cited in Broadway’s papers, are here 
enumerated for the first time. 
Recently, Dr. Wilbur G. Downs and Dr. 'T. H. G. 
Aitken of the Trinidad Regional Virus Laboratory in 
Port-of-Spain have made extensive and discerning collec- 
tions of native orchids. They have brought these collec- 
tions into cultivation and have prepared a series of out- 
standingly excellent photographs of the living plants. 
Many represent species not hitherto illustrated. A com- 
plete set of these photographs is deposited in the Orchid 
Herbarium of Oakes Ames, where the corresponding 
specimens have been identified and are preserved. 
For the purpose of easy reference for both collector and 
orchid lover who may not be familiar with any phylo- 
genetic system of generic classification, the genera, and 
under them the species, are here arranged alphabetically. 
Specimens for this study have been available from the 
Trinidad Herbarium at the Imperial College of Tropical 
Agriculture, from the Royal Botanic Gardens, Kew, 
from the Orchid Herbarium of Oakes Ames of the Bo- 
tanical Museum of Harvard University and from the 
Gray Herbarium of Harvard University. Several new
