paniculate (perhaps rarely racemose) ; peduncle and rachis 
filiform, below the floriferous portion provided with three 
or four loose scarious more or less evanescent sheaths. 
Floral bracts minute, amplexicaul, acute. Pedicellate 
ovary glabrous. Flowers membranaceous, sparse. Lateral 
sepals oblong to oblong-lanceolate, slightly oblique, 6.5— 
6.9 mm. long, 2.2—2.6 mim. wide, acute, 5-nerved. Dor- 
sal sepal oblanceolate-oblong, 6.1—7 mm. long, 2—2.4 mm. 
wide, acute, 5-nerved. Petals oblanceolate-linear, about 
6.38 mm. long, up to 1 mm. wide, subacute to obtuse, 
1-nerved. Lip simple, adnate to the basal part of the 
column, cuneate-spatulate in outline, free portion of lami- 
na 7-7.6 mm. long, 4-4.5 mm. wide, shallowly retuse at 
the apex, more or less distinctly indented on each side at 
the middle, margins irregularly subcrenulate; dise with a 
pair of short laminate keels below the middle. Column 
terminating in two prominent erect obliquely triangular 
wings, with a low small tooth located between them. 
Epidendrum cyanocolumna is named from the wings 
of the column, which when first examined were sky-blue, 
the central tooth was red-purple. Its nearest ally is J1. 
tripunctatum Lindl. (in Bot. Reg. 27 (1841) Mise. p. 66) 
from which it differs in having smaller flowers, an inflo- 
rescence subequalling or exceeding the leaves and much 
narrower petals. 
The second specimen cited varies from the type in 
having three leaves (the type appears to be consistently 
2-leaved). Furthermore, some of the veins of the lip show 
small crest-like protuberances near their extremity; these 
are apparently lacking in the type.
