tensively connate with the laterals. 
In the illustration of Lepanthopsis microlepanthes, fig. 
5 clearly shows the post-pollination aspect of the gy- 
nostemium. The semi-globular protuberances, one with 
a pollinium attached to its summit, represent the ex- 
traordinary development that takes place after pollina- 
tion is effected. This development of the stigmas is also 
found in L. melanantha and in Pleurothallis ruscifolia, 
but if my conclusions are justified, the end-result simply 
masks, in P. ruscifola, the structural peculiarities ante- 
cedent to pollination. 
In adding P. melanantha and P. microlepanthes to 
Lepanthopsis it should be remarked that they differ con- 
spicuously from JL. floripecten in the nature of the in- 
florescence. The flowers are not transversely inserted, 
but are distichous and in two ranks.

It was noted above under Lepanthopsis anthoctenium, 
that in Urban’s Symbolae Antillanae, Alfred Cogniaux 
had referred Wright’s Cuban plants distributed under 
numbers 1509 and 3342 to Pleurothallis melanantha. The 
only satisfactory explanation of this procedure seems to 
be that the plants representing these numbers were a 
mixture or at least that no. 1509 is represented by both 
species. In the Gray Herbarium where the plants num- 
bered 1509 and 8842 are mounted on the same herbarium 
sheet, Lepanthopsis anthoctenium and L. melanantha are 
represented under both numbers. Although these species
