A NEW CAMPYLOCENTRUM FROM THE 
DOMINICAN REPUBLIC 
BY 
Oakes AMES 
THE SARCANTHINAE of the West Indies consist of 
several genera in which some of the species are aphyllous 
and in flower-structure call to mind the Old World spe- 
cies of Angraecum and its allies. An altogether puzzling 
species of this alliance has been received from the Dom- 
inican Republic where it was collected by L. Ariza Julia 
near Ia Romana. The flowers are angraecoid in appear- 
ance, resembling somewhat the flowers of Mystacidium 
distichum, yet they exhibit the distinctive characters of 
Campylocentrum, differing from the known West Indian 
species in having an elongated slender spur. From spec- 
imens preserved in alcoho! the roots appear to have been 
greenish and doubtless possess chlorophyll as is true of 
species of Taeniophyllum, exercising the functions asso- 
ciated with foliar structures. The abbreviated stems are 
concealed by the mass of these roots from among which 
the flower-shoots emerge. Krom the specimens examined 
it would seem that the flowers open in succession, only 
one flower being expanded while the succeeding ones are 
still in bud.
