Gongora maculata Lindley var. latibasis C. 
Schweinfurth & P. H. Allen var. nov. 
Herba floribus majoribus atque labelli hypochilio per- 
lato basi triangulari nec vere cornuto a specie differt. 
Vegetative portions not seen. Pseudobulbs said to be 
subglobose, about 5 cm. in diameter, deeply suleate. 
Leaves about 80 cm. long and 10 cm. wide, grayish 
green. Flowers (of which I have examined two) some- 
what larger than those of Gongora maculata; buds tawny 
yellow; sepals dark blood-red; petals and column green 
with small red spots. Dorsal sepal broadly ovate-elliptic, 
acute, adnate to the middle of the column, lightly con- 
cave, with revolute margins, about 2.3 cm. long and 1.3 
cm. wide when expanded. Lateral sepals larger, wide- 
spreading, obliquely triangular-ovate, acuminate, with 
revolute margins, the base being long-adnate to the 
column-foot, about 3 cm. long to the posterior point of 
insertion and 2 cm. wide. Petals relatively small (as in 
the genus), long-adnate to the column, the free portion 
being sigmoid, linear, acute, strongly incurved in natural 
position, Lip very fleshy, about 2.2 cm. long, adnate to 
the abbreviated free apex of the column-foot; hypochile 
(when viewed from above) subquadrate-triangular with a 
very broad subbasal portion which is destitute of horns, 
the anterior portion in front of the broad rounded sinus 
produced on each side into an erect bristle; epichile nar- 
rowly triangular and acuminate when viewed from above, 
laterally compressed and broadly triangular with a re- 
curved apex when viewed from the side. Column arcu- 
ate, slightly enlarged above, about 2 cm. long. 
By reason of its large size, this concept appears to be 
quite distinct from the other members of the genus Gon- 
gora which have been examined. It is unusual, among the 
other members of its alliance, in having a lip with a very 
broad triangular basal portion which lacks any true horns.
