on the upper surface, slightly narrowed above the middle, 
rounded at the apex. Column equalling the petals, sim- 
ilar to the column of S. Standleyi Ames. 
Stelis Skutchi is closely allied to S.Standleyi, differ- 
ing from it chiefly in the dissimilarly proportioned sepals 
and lip. It is noteworthy that the dorsal sepal in S. 
Skutch is strikingly unlike the lateral sepals, being ob- 
long-lanceolate rather than ovate-lanceolate. 
In the same locality where the type was found, Dr. 
Skutch discovered a single plant in a more advanced state 
of maturity. The flowers of this single specimen are iden- 
tical with those of iS. Shutchiu, but the vegetative parts 
show differences. For example, the plant is 80 cm. tall 
and the leaves are from 1.4—2 cm. wide, borne on second- 
ary stems which attain a length of 11 em. 
S. Shkutchii is a member of the alliance to which S. 
rubens Schltr. belongs.
