Parasitic ? 
Stems about five or six inches in height, erect, considerably swollen and 
jointed ; joints two or three inches long, cylindrical, of a dark hue, pel- 
lucid and green, in this respect, as Mr H. Shepherd remarks, resembling 
the stems of a Balsam or Tradescantia ; each joint has a large sheathing 
scale, acuminated at the point. These old stems remain after flowering, 
and form linear, oblong, leafy bulbs, often tinged with red. From the 
summit of the stem rise four leaves, placed close together, each about four 
inches in length, ovate, erecto-patent, of a thin membranaceous texture, 
and of a bright yellow-green colour, strongly nerved and plaited, the 
margin waved. 
The jiomer-stalk, about eight inches long, springs from the centre of the 
leaves, it is erect, leafless, remarkably angular, the angles almost winged, 
of a purple colour below, above paler, almost white. 
Flowers forming a loose, elongated spike, with very small, lanceolate, purple 
bracteas. Corolla \ery patent : the three outer petals oblongo-lanceolate, 
their margins re volute, the upper one rather the longest and narrowest, 
purple green : the two inner petals linear, their margins revolute, purple. 
The Lip has its sides curved upward, the extremity reflexed, with two 
tubercles at the base ; of a deep purple colour, greenish at the margin. 
Column whitish, quite exposed, semicylindrical, incurved, the upper part 
slightly winged on each side of the stigma. Anther operculiform, 2-celled, 
and covering four ovate, deep yellow, waxy pollen-masses, which are 
placed in pairs. Germen elongate, whitish, twisted.
