NOTES CONCERNING SOME 
WEST INDIAN ORCHIDS 
BY 
Donovan S. CorRRELL 
I. THE GENUS BROUGHTONIA AND 
SOME OF ITS ALLIES 
In 1813, Robert Brown proposed the genus Brough- 
tonia to include Dendrobium sanguineum Sw. (based on 
Epidendrum sanguineum Sw.). He distinguished it from 
closely allied genera by the long sepaline tube which is 
adnate to the ovary and by the four pollinia. 
In 1858, Lindley proposed the genus Laeliopsis based 
on Cattleya domingensis Lindl]. He wrote at the time 
(in Paxton Flow. Gard. 3, p. 155): 
*“What is the genus of this beautiful plant? Lariia? no; because it 
has only four pollen-masses—BrovucGuTonta? no; for although its flower 
is deeply cuniculate, yet it has not a long external adnate spur and 
decurrent sepals—Eripenprum? no; for it wants the unguiculate lip 
more or less united to the column—Carrtirya? still no; although we 
once thought it one; for the flowers are membranous, the veins of the 
lip bearded, and the habit quite different.’’ 
Lindley referred three of his own species to this genus 
(Laelia Lindeniit (from Cuba), Broughtonia chinensis 
=Epidendrum chinense (Lindl/.) Ames and EHpiden- 
drum cubense) but failed to make the combinations under 
Laeliopsis. He separated Laeliopsis from Broughtonia 
primarily on the basis that the flowers lacked a sepaline 
tube or as he stated, ‘‘....a long external adnate spur
