NEW OR NOTEWORTHY ORCHIDS 
This variety differs from the species in the proportions 
and lobing of the labellum. This organ is erect and parallel 
to the column in natural position with the sides of the basal 
portion erect and tubular-involute and the terminal por¬ 
tion strongly recurved at its middle, 13-15.5 mm. long, 
sharply 3-lobed beyond the middle; basal portion when ex¬ 
panded obovate-elliptic, 9.5-11 mm. long to the free rounded 
apices (side lobes), 7.2-8 mm. wide, center traversed for 
about two-thirds of its length by an oblong flat or slightly 
concave fleshy callus more or less pubescent; middle lobe 
extremely fleshy, ovate when forcibly expanded, 6-6.8 mm. 
long, about 3-5 mm. wide, obtuse, densely papillose, more 
or less conduplicate, margins revolute.
