Anepiphytic herb with simple or branched stems up 
to 8 dm. long. Stems multiarticulate, indurated but not 
greatly thickened, the segments mostly 1—1.5 cm. long, 
the older ones with the shredded remains of the old leaf- 
sheaths, yellow in color, the younger parts of the stem 
covered with the loose leaf-sheaths: leaves lanceolate, 
acute, mostly with five main nerves, 8-4 cm. long, 7-9 
mm. broad (as far as known), articulated to the striated 
sheaths; inflorescence usually 2-flowered, borne at or 
near the end of the stem: flowers rather small, white, 
about 1.5 cm. long: dorsal sepal lanceolate, acute, 5- 
nerved, joined with the lateral sepals for a short distance 
at the base, about 10 mm. long and 4 mm. broad; lat- 
eral sepals attached to the column-foot, lanceolate, ob- 
tuse or acutish, slightly oblique, 5-nerved, blade about 
10 mm. long and 4 mm. broad, prolonged into a mentum 
which is closed for only about 3 mm., the mentum (and 
column-foot) about 6 mm. long: petals elliptic, acute 
or obtuse, 3-nerved, about 10 mm. long and 4.5 mm.
