quill, creeps on the substance to which it attaches itself for a 
few inches, is branched, and bears Yather numerous, alternate, 
very thick and fleshy, elliptical, sessile eaves, convex at the 
back, nearly plane on the upper surface, but marked with three 
rather deep longitudinal furrows. In a young state there are 
sheathing, short, membranaceous stipules at the base of the 
leaves, which are deciduous. From the base of the leaves again 
arise the slender, filiform flower-stalks, with one or two mem- 
branaceous dracts near the base, scarcely exceeding the leaf in 
length, terminated by a raceme of white flowers three to four 
inches long. Ovary small, tapering into a pedicel. Sepals and 
petals long, linear, acuminate ; the two inferior sepals gibbous 
at the base. Zip small, quite concealed by the perianth, close- 
pressed to the column, three-lobed, middle lobe the largest, 
acute, reflexed, yellow, with red spots; the disk bearing three 
elevated plates or crests, which are crisped ; side-lobes white, 
with a few red spots within.
