Dorsal sepal oblong-elliptic to oblanceolate, 16-23 mm. 
long, 4-6 mm. wide, obtuse to acute, somewhat thickened 
and carinate at the tip, tending to be revolute on the 
margin. Lamina of the lip subquadrate-ovate or sub- 
quadrate-reniform in general outline, 7-11 mm. long, 
13.5-16 mm. broad, distinctly 8-lobed ; mid-lobe quadrate 
to subquadrate-ovate, apex usually triangular acute and 
apiculate or rarely truncate and slightly retuse (transition 
to var. firmum). Column as in other forms, with the cli- 
nandrium usually lacerate or rarely only denticulate. 
Var. Storku grades into both var. firmum and the 
typical form of the species and in a lesser degree into var. 
simulacrum, From the species proper and from var, fir- 
mum it is separable by the triangular-acute apex of the 
mid-lobe of the labellum. From var. simulacrum the shape 
and larger size of the lip separate it clearly.

Plant including the inflorescence 18-26 cm. tall. 
Stem rather more slender than its nearest ally var. Storhv, 
somewhat flexuous. Leaves oblong, narrowed toward the 
ends, 1-4 cm. long, 2-10 mm. wide, about 4 cm. apart, 
obtusely and unequally bilobed at the tip. Flowers small- 
er than commonly the case in the other forms, borne in 
umbel-like clusters. Pedicel with the ovary slender, up 
to 8 cm. long. Lateral sepals obliquely elliptic-oblanceo- 
late, 9-10 mm. long, 8 mm. wide, apex thickened and 
‘arinate on the exterior surface and short-acuminate.
