muricata is only shortly clawed or has a cuneate base with 
the lamina distinctly acute or apiculate in front. 
The first character (that of the ciliation of the leaves) 
is apparently a stable feature, the leaves of the Peruvian 
material referred to D. maculata being always more or 
less ciliolate on close examination, whereas those of the 
specimens referred to D. muricata appear to be almost 
invariably entire. 
On the other hand, the Peruvian specimens which have 
these ciliolate leaves have a lip which varies from short- 
clawed to elongate-cuneate at the base and the apex of 
the lamina is invariably apiculate (sometimes with a 
rounded forward margin) or even sharply acute. 
It seems, therefore, that the lip of D. maculata is 
rather polymorphic (as it is in typical D. muricata), but 
it appears probable that it is always more or less strongly 
apiculate—a character that may readily have been over- 
looked in the typical specimen. Since, however, this 
concept was described and figured with a linear-clawed 
lip, it may be well to recognize this tendency. 
For purposes of simplification in these closely allied 
concepts, therefore, it seems reasonable to consider D. 
maculata as a variety of the older concept D. muricata 
(based on Cymbidium muricatum Sw.) of which an excel- 
lent description and floral analysis is given in Fawe. & 
Rendle Fl. Jam. 1 (1910) 137, t. 80, figs. 22-25. Thus 
we segregate var. maculata as having leaves with a cilio- 
late apical portion and a lip which is either long- and nar- 
rowly clawed or with a narrowly cuneate base.
