which is 11-12.5 mm. long, 4.2-5.5 mm. wide, sharply 
bidentate at the apex, conspicuously bicarinate on the outer 
surface, 6-nerved. Dorsal sepal lanceolate, 8.6-10 mm. long, 
2.8-3.5 mm. wide, acuminate, dorsally strongly carinate, 
3-nerved. Petals triangular-lanceolate, very oblique below 
with base oceupying the long eolumn-foot, 7.1-8.5 mm. long 
on the posterior margin, 4-5 mm. wide along the column-

rior margin nearly straight, anterior margin dilated near the

the eolumn or the summit of the eolumn-foot, sharply re¬ 
flexed near the base, elliptic-subquadrate, about 4.5-6.5 mm. 
long, 3.6-5 mm. wide, bilobed and minutely apiculate at the 
apex. Disc 5-nerved, a very fleshy slightly bilobed callus

This plant is undoubtedly a member of Schlechter’s new 
genus Systeloglossum which is allied to Aspasia and to Coch- 
lioda. It differs from S. costaricense Schltr., the only other 
described speeies, in its larger flowers, acuminate sepals, dis¬ 
similar petals, different lip-calli and broad crenulate column¬ 
wing. In fact the acuminate sepals suggested the specific name. 
The deseription was made from dried speeimens to¬ 
gether with flowers preserved in formalin.
