On receipt of the analytical floral drawing of Ste/is 
apiculata Schitr., it appeared that S. isig@nis was insep- 
arable from that species. However, the name apiculata 
is invalidated by the prior use of the name by Lindley 
in 1858 and therefore the later name insignis should re- 
place it.

Pleurothallis peraltensis Ames in Sched. Orch. 6 
(1923) 65. 
A comparison of the type material of these species 
fruls to show any structural difference between them. In 
each species the number of racemes borne by a single 
stem appears to vary, being commonly one or two in P. 
Blaisdellu and often numerous in P. peraltensis.

The type of P.choconiana agrees very well with the 
typical form of P. marginata, except that it has the lateral 
sepals entirely or mostly connate whereas the records of
