NEW OR NOTEWORTHY ORCHIDS 
lamina when expanded obovate in outline, about 5.7 cm. 
long in the center and 4.4 cm. or more wide beyond the mid¬ 
dle, deeply bilobed at the apex, anterior margins lacerate- 
erose. Disc adorned at base with 7 keels of which the cen¬ 
tral one is a broad flat linear-lanceolate callus, anterior part 
traversed by 9 keels which are more or less crenulate above, 
the lateral one on each side branching. The longest keels 
terminate about 5 mm. below the apiculate apex. Column 
3 cm. long, slender, slightly winged on each side of the upper 
part, flexuous when seen from the side; clinandrium lobulate. 
Anther triangular, granulose. 
The description was made from a dried plant, from a flower 
preserved in alcohol, and with the aid of the collector’s notes. 
Sobralia Bouchei closely resembles S. panamensis Schltr., 
but it differs strikingly in having glabrous stems and many- 
carinate lip of different color. 
Panama, Adrien M. Bouche s. n., March-April 1930. 
2200 feet altitude. Terrestrial and epiphytic. (Type in 
Herb. Ames No. 35595.) Collector’s notes state that the 
epiphytic plants, reaching 50 cm. in height, are the sturdier 
and occur at an altitude of 2500 feet. The terrestrial plants, 
growing at an elevation of 2000-2200 feet, are said to be 
Weak and sprawling and to have smaller flowers which lack 
the white margin to the lip. Judging from a water-color 
drawing sent by Mr. Bouche, the keels of the lip are yellowish.
