Leaves alternate, pointing every way, distant, ovato-
laneeolate, acuminate, nearly plane, longitudinally
veined, a little sheathing at the base, the
lower ones wider, acute rather than acuminate,
beneath frequently purple.
Bracteas resembling the leaves, the lower ones twice

ones gradually smaller, narrower, all of them lanceolate,
acuminate, somewhat keeled, patent,
' green.
Flowers disposed in a lax spike, the lower ones more

part of the column, the apex obtuse and recurved,
within rugose, yellow-orange, near the base having
three longitudinal elevated lines that are
transversely rugose.
Column a little shorter than the labellum, erect, straight,
somewhat cylindrical, white.
An th er terminal, fixed by its base, articulated, erect,
