Character of the Genus, Epidendrum. External folioles of 
the perigone spreading, nearly equal, the internal equal or narrower, 
very seldom broader. The labellum, by means of its claw, either en¬ 
tirely, or partly cohering to the margins of the column, the limb entire 
or divided, the disc generally callous, ribbed or tuberculated, the limb 
is also occasionally prolonged into a spur adhering to the ovary. 
Column elongated, clinandrium, margined, often fimbriated. Anther 
fleshy, two- four- celled. Pollen-masses four with a similar number 
of doubled tails. 
Description of the Species, Epidendrum umbellatum. 
Epiphyte a span or half a foot long. Stems numerous, round, simple, 
the lower part covered with the persistent petioles of former leaves. 
Leaves alternate, distichous, vaginating, leathery, without conspicu¬ 
ous veins, oblong, from an inch to an inch and a half in length, emar- 
ginate, and generally not uniform, of a light green colour. Inflor¬ 
escence umbelled, the peduncle short, opening from the bosom of 
the upper leaf, and bearing about five flowers. Flowers of a green¬ 
ish white colour and waxen aspect; external folioles linear-oblong, 
obtuse spreading as well as the internal ones, which are linear, nar¬ 
rower, revolute at the margins. Labellum entire, rounded, spread 
out, transverse, having two callosities at the base; attached to the
