stout, with a rather large free acute bract close to that 

 subtending the terminal pedicel. Flower solitary, white, 

 relatively very large. Segments of perianth white, usually 

 without markings but sometimes with a faint pink stripe on 

 the outside ; nearly equal in length, glabrous except at the 

 extreme base, not contracted into caudae, gradually diminish- 

 ing into finely acuminate non-clavate points, the latter rarely 

 glandular. Dorsal sepal erect, lanceolate^ incurved, concave, 

 about 2*5 cm. long, the base rather wide. Lateral sepals 

 wider, free, spreading, lanceolate, somewhat contracted at 

 the base. Petals spreading, lanceolate, narrower than the 

 lateral sepals. Labellum on a short claw, white with narrow 

 pink margins, a few pink splashes on the lateral lobes, 

 obscurely 3-lobed, ovate, blunt at the apex, about 15 mm. 

 long and 11 mm. wide; the lower half erect against the 

 column with entire margins; thereafter recurved with serru- 

 late or crenulate margins; the lamina flattened transversely, 

 the calli pink narrowly linear in 4-6 rows ending near the 

 middle. The column nearly as long as the labellum, incurved, 

 speckled with pink, widely winged in its upper half. Anther 

 shortly mucronate, valvate, 2-celled. Stigma circular, with 

 short triangular rostellum in its upper border between the 

 bases of the anther cells. Pollinia in 2 pairs, of the usual 

 type. Ovary exceedingly glandular-hairy.

The new species differs from C. Pater soni in its dwarfed 

 habit, in the absence of tentacles to the perianth segments, 

 and in the absence of definite glandular tips to those seg- 

 ments. Its sepals are about equal in length to the petals, 

 whereas they are considerably longer than the latter in C. 

 Patersoni. The tip of the labellum is blunt and the margins 

 practically entire in C . pumila, whereas the tip is acute and 

 the margins acutely toothed in the other species.

n. var. Flowers pale greenish-yellow; or yellow with chocolate 

 markings down the middle of the perianth segments, also down 

 the middle and on the sides of the labellum. Lateral sepals 

 connate.
