cylindrical, about 5 mm. in diameter in living specimens. 
Perianth segments porrect, hardly spreading. Lateral 
sepals greenish, 6.9—7.5 em. long, 11-14 mm. wide near 
the middle, 6 mm. wide at the base, oblong-lanceolate, 
lightly cucullate at the pointed apex, fleshy. Dorsal sepal 
similar. Petals 7 em. long, 9mm. wide, narrowly lanceo- 
late, acute, with the mid-rib prominent on the outer sur- 
face. Labellum 6.5—7 em. long, adnate for about one half 
of its length to the column, forming with the basal half 
of the column a slender tube which is strongly inflated 
above, the free part lightly 3-lobed and 8-38.5 em. wide; 
lateral lobes 1.5 em. long, 1.5 em. wide, coarsely lacerate- 
fringed with the segments of the fringe attaining a length 
of 5 mm.; mid-lobe 1.5 em. long, 1.4 em. wide, semi- 
orbicular, with a small half-round callus near the tip, 
the basal margin on each side paucifimbriate, the upper 
surtace densely covered with retrorse complanate elon- 
gated appendages, the longest ones about 5 mm. in length, 
in the throat of the labellum these appendages become 
very much reduced diminishing to verruciform emergen- 
ces on the nerves in front of the penicillate crest that is 
situated opposite the stigmas; the slender portion of the 
throat is densely covered almost to the base with erect 
or spreading glandular hairs. Column about 5 cm. long, 
weakly sigmoid, slender, densely glandular-hairy on the 
anterior surface; anther, pollinia and stigmatic portions 
as in Vanilla fragrans.
