92 CXLVIII. ORCHIDEZ. (J. D. Hooker.) [ Corymbis. 
Nilghiri in flower only. The ripe fruit of the Andaman species is 1 in. long. The 
Ceylon one has much shorter points to the leaves, but the fruit is as large as in 
Blume’s figure. Blume distinguishes C. assamica by the column being as long as the 
capsule; which they are in typical veratrifolia. 
2. C. longiflora, Hook. f.; leaves elliptic-lanceolate acuminate, 
flowers 11-2 in. long, sepals very slender with very narrow blades, petals 
oblanceolate, blade of lip orbicular cuspidate. 
Perak, Scortechini, King’s Collector. Matacca, Maingay (Kew Distrib. 
1661). 
Stem 8-10 ft. high, as thick as the little finger; leaves much broader than in 
C. veratrifolia, and flowers twice as large, white. Column long. Fruit not seen. 
3. C. rhytidocarpa, Hook. f.; leaves lanceolate acuminate, flowers 
1 in. long, sepals narrowly oblanceolate, petals oblanceolate crenate, blade 
of lip triangular-ovate acuminate, ribs of fruit strong wrinkled. 
PERAK, Scortechini, King’s Collector, Wray. 
Stem 4 ft. high and leaves as in C. veratrifolia, from which the broader petals, 
form of the lip, and deeply ridged fruit 1-1} in. long with wrinkled ribs 
distinguish it. Column long. 
4. C. brevistylis, Hook. f.; leaves 5-6 in. elliptic acuminate sub- 
petioled, column 4 in. long. 
PERAK ; on limestone rocks, King’s Collector. 
Stem 1-2 ft., slender. Leaves 7-nerved, 2-3 in. broad. Panicles few-fld. Young 
fruit 1 in. long.—A very distinct species, probably the same as an undescribed Javan 
one,

Terrestrial, glabrous, leafy herbs. Stem often branched, roots rigid. 
Leaves sessile, membranous, subplicate; petiole sheathing. Flowers small, 
in axillary and terminal sessile or peduncled spikes; bracts coriaceous, 
often imbricate, strongly nerved. Sepals connivent, lateral more or less

superior, sessile at the base of the column, cymbiform or produced into an 
obtuse spur, undivided, acute or with a reflexed tip, disk with short or long 
intramarginal ridges on lamellw; column short or long; rostellum long, 
erect, at length 2-tid; stigma anticous; anther erect, acute or acuminate, 
cells contiguous; pollinia 2, clavate, 2-cleft, caudicle long or short, gland
