nerve projecting. Peduncles one to four in the axil of the 
leaf, up to 6 cm. long, filiform, rigid, with several remote 
abbreviated tubular bracts. Raceme about 1.5 em. long, 
bearing as many as twenty distichously placed yellow 
flowers. Bracts of the raceme infundibuliform, scarious, 
equaling the pedicels of the flowers. Flowers .75 mm. 
apart, transversely attached, contiguous. Lateral sepals 
about 8 mm. long, connate to within 1 mm. of the tip, 
forming an oblong bifid lamina 1.5 mm. wide, conspicu- 
ously carinate on the exterior surface, acute or subacute, 
united at base with the dorsal sepal, 1-nerved. Dorsal 
sepal 2mm. long, 1 mm. wide, ovate, obtuse or subacute. 
Petals spreading, about .5 mm. long, oblong-elliptic, 
rounded at the apex, 1—nerved. Labellum 1 mm. long, 
scarcely 1 mm. wide, elliptical, conspicuously 3-nerved. 
Column very short, dilated upward; stigmas orbicular, 
widely separated. Anther papillose. Pollinia two. 
In the enlarged drawing of the raceme, two flowers 
near the summit are shown with the dorsal sepal inflexed. 
This condition seems to accompany the development that 
follows pollination. In flowers that exhibited this pe- 
culiarity I found pollen masses adhering to the stigma. 
The petals had become inflexed in such a way that they 
concealed the column; the dorsal sepal was closely applied 
to them, so as to form a protective covering over the 
pollinated stigmas. 
In Edwards’ specimens there is a wide range in the 
size of the plants. The production of the first raceme oc- 
curs when vegetative development is characterized by 
very short secondary stems. As the second, third and 
fourth peduncles appear, vegetative development has pro- 
gressed rapidly. This phenomenon is clarified by two 
drawings, one showing a young plant that is flowering 
for the first time, the other showing an elongated stem 
which bears four peduncles.
