Eipidendrum patulipetalum, of which the description is 
supplemented by a floral analysis made under the super- 
vision of Dr. Schlechter, has sepals which are exactly as 
small as those of J. parviflorum (Eh. paniculatum var. 
linearifolium). As drawn, the lip is even smaller than in 
typical 27. parviflorum and is thus more similar to the 
Ecuadorian collection (Penland & Siammers 204) referred 
to £. parviflorum. Moreover, the two basal calli are rep- 
resented as more prominent than in the Ecuadorian col- 
lection of £7. parviflorum. Considering the known varia- 
bility of the lip in this alliance, however, it seems entirely 
justifiable to reduce this concept.

Plant 80 cm. or more tall (stem broken off). Stem 
stout, up to 1 cm. in diameter near the base. Leaves 
elliptic or oblong-elliptic, up to 18 em. long and 4 cm. 
wide. Inflorescence loosely paniculate; peduncle about 
22 cm. long, provided with four strict oblong-lanceolate 
conduplicate spathes. Flowers cream-colored, larger than 
in the species. Dorsal sepal 18-19 mm. long, 5 mm. wide 
above. Lateral sepals 19.6-20 mm. long, 5.6—-6 mm. 
wide above. Petals 18-19 mm. long, 1.2-1.5 mm. wide 
above. Lamina of lip about 8.7 mm. long and 16 mm. 
wide across the lateral lobes when expanded ; lateral lobes 
broadly dolabriform, irregularly lobulate on the rounded 
outer margin; mid-lobe from a quadrate base abruptly 
dilated into a pair of subhorizontal lightly recurved ob- 
long lobules, lightly retuse and sharply apiculate in the 
middle; dise with a pair of small rounded basal calli sur-
