late-oblong, 11-22 mm. long, 3.2-7 mm. wide, often 
slightly carinate at the apex on the exterior surface, sub- 
acute to short-acuminate at the apex. Petals filiform- or 
linear-spatulate to linear-oblanceolate, 10.8—20 mm. long, 
1.2-2 mm. wide, obtuse to acute. Labellum much like 
the typical form in general outline, 5-19 mm. long, 
8.5-20 mm. wide, distinctly 8-lobed; mid-lobe usually 
‘rather subquadrate, rarely tending to reniform or quadrate- 
ovate, its apex truncate or retuse or somewhat bilobed, 
often apiculate; disc much as in the typical form with two 
basal calli, but the mid-nerve is apt to be thickened even 
to the apex of the lip. Column adnate to the claw of the 
lip and its clinandrium lacerate or rarely only dentate. 
Var. firmum is set off from the typical form by having 
the mid-lobe of the lip at most little broader than long, 
subquadrate. From var. Storki and var. simulacrum it is 
separable by the truncate, retuse or somewhat bilobed 
apex of the mid-lobe of the lip. The leaves in typical var. 
jfirmum are often narrower than in the typical form of the 
species, but they are not constant in this respect.

10. 
Plant 12-87 cm. tall (including the inflorescence ). 
Stems usually rather stout and congested. Leaves oblong- 
or lanceolate-elliptic to elliptic, 1.5-8.8 em. long, 5-25 
mm. wide, unequally bilobed at the obtuse apex. Leaf- 
sheaths complanate and dilated upward. Inflorescence 
terminal, subumbellate, 2- 6-flowered. Flowers medium- 
sized, greenish, long-pedicelled. Lateral sepals oblong or 
elliptic-lanceolate to oblanceolate or oblong-elliptic, 16— 
22 mm. long, 5-6 mm. wide, slightly asymmetric, acute 
or acuminate, thickened and slightly carinate at the tip.
