rounding a fleshy median ridge which extends to the apex 
of the lip, the median ridge being supported on each side 
by a shorter smaller ridge. Column about 14.2 mm. long. 
Pollinia four, complanate, the two outer being semilu- 
nate and the two inner smaller and lanceolate in outline. 
In view of the extreme variability in the size of the 
flowers and in the form and lobing of the lip in 7. pan- 
iculatum, 1 consider it advisable to recognize only as a 
well-marked variety this plant which differs from the 
usual form in having a relatively elongate peduncle with 
several conduplicate spathes, and larger flowers with the 
lateral lobes of the lip strongly flabellate and lobulate on 
the outer margin and especially in having a prominent 
quadrate-unguiculate mid-lobe.
