NEW OR NOTEWORTHY ORCHIDS 
wide, subquadrate, apiculate, 3-nerved, slightly narrowed 
toward the front, apparently 3-lobed; lateral lobes porrect 
and obtuse, united in front of the middle lobe by a mem¬ 
brane; middle lobe acute, sulcate, ascending, very fleshy, 
exceeding the blunt lateral lobes. Column minute. 
Allied to Sielis tricuspis Schltr., which is different in 
habit. The labellum of these species is similar in being 
prolonged in front to form a cusp-like terminal lobe, but 
different in the texture being more fleshy in S', tricuspis, 
which has a distinct callus on the disc between the lateral 
lobes. The sepals of S. tricuspis are acuminate and more 
narrowly ovate than in S. cuspidata.
