ORCHIDS OF JAMAICA 



in the "Flora of the British West Indies," it has been 

 of interest to revise his determinations by comparison with 

 the original collection. Prof. Ignatius Urban of Berlin has 

 generously entrusted to us the volume of Swartz's " Icones 

 Ineditae," and has allowed us to cite the drawings. During the 

 preparation of our work Prof. Urban has given a detailed account 

 of the botanical exploration oi Jamaica since the publication 

 of Grisebach's " Flora " in his " Symbolse Antillanse " (vi., 

 pp. 70-131, 1909). To Prof. Cogniaux, who is elaborating the 

 Orchids of the West Indies for the " Symbolse," we are indebted 

 for the loan of specimens and helpful information. 



Our descriptions of the genera have been drawn up with 

 special reference to the species which occur in Jamaica. For 

 measurements we have used the metric system, but for con- 

 venience of tourists we have added English measures for the 

 height of the plant and the size of the flower. The figure below 

 renders possible a ready comparison of the two systems, e.g. 

 2 • 5 cm. are equivalent to an inch, 2 mm. to ^^ inch, and 1 dm. 

 to about 4 inches.

The J.P. (Jamaican Plants) numbers cited are those given by 

 Sir D. Morris to the species in the Jamaican Herbarium ; the 

 numbers cited as Fl. Jam. (Flora Jamaicensis) are those attached 

 to specimens, as collected, later. 



The mark *' ! " indicates that we have seen a specimen. 



In order to conform to the international rule^ which requires 

 that diagnoses of new species shall be published in Latin, 

 descriptions of novelties have been inserted in the " Journal 

 of Botany," and are quoted here from that work.
