Judging from a photographic record in the Ames Her- 
barium of the type of this species, the leaves appear to be 
oblong-elliptic, not ligulate as described; they measure 
scarcely more than 3 cm. in length and 1 cm. in width, 
whereas they are described as 3—4.5 em. long and almost 
8-11 mm. wide. 
Of further interest is an imperfect Hower in a packet 
labelled ‘‘Maxillaria xanthorhoda, Hort. Dahlem’’ in the 
handwriting of Dr. R. Mansfeld. This shows a lateral se- 
pal which is neither obovate nor oblong-obovate (as de- 
scribed and illustrated), but lanceolate-oblong as in M. 
variabilis Batem. The other sepals and the lip are too 
fragmentary to afford any evidence. Perchance this 
flower was mistakenly derived from a specimen of M. 
variabilis, for it was stated on the packet to have been 
collected in April 1983, whereas the type of M. wantho- 
rhoda was said to bloom in April 1918.

Several Peruvian collections prove to be referable to 
the Bolivian M. wylobuflora. There appear, however, to 
be certain discrepancies which should be enumerated. 
The pseudobulbs are apparently ellipsoid-cylindric 
with an abrupt linear complanate beak (in the dried spec- 
imen), rather than linear and slightly narrowed above as 
described. The inflorescences are mostly shorter than the 
leaves, not almost equaling them as cited. The median 
callus on the dise of the lip extends to well above the 
middle, rather than almost to the middle as stated, and 
has a simple, acute, not a 4-denticulate apex.
