soid and 5.7 cm. or less long, with sometimes an abruptly 
narrowed apical portion. Surrounding the pseudobulb 
is at least one pair of unequal distichous conduplicate 
sheaths of which one is leaf-bearing. The lamina of the 
leaf is elliptic-oblong, not oblong-lanceolate as described, 
and measures 29 cm. in length and 5 em. in width, where- 
as those of the types appear to be 23.75 cm. or less long 
and 4 cm. or less wide. The lateral sepals and petals seem 
to be lanceolate or oblong-lanceolate when the revolute 
margins are expanded (not triangular-oblong as de- 
scribed). The lip appears to be oval in outline, rather 
than obovate-oblong as cited.

After examining an excellent photograph of the type 
collection of Camaridium exaltatum in the Ames Her- 
barium, there are evident certain discrepancies from the 
type description. First in importance, I am unable to 
detect any suggestion of pseudobulbs which are described 
in the diagnosis (1. ¢.). Again the sepals appear to be 
oblong-lanceolate (not linear) with both dorsal and _lat- 
eral sepals about 1.8 cm. long (the lateral sepals are de- 
scribed as 2.8 cm. long). 
A recent collection from Sandia in the Province of 
Puno (McCarroll 123) has somewhat smaller flowers than 
typical, the sepals being 1.5-1.7 cm. long. Moreover, its 
lip differs in having a broadly ovate or ovate-triangular 
(not oblong) mid-lobe and in the disc bearing only a small 
oblong sulecate (not an elongate navicular) callus.
