of the axis of the scape after flowering, and that the appearance of an acute lip is 
due to the infolding of its margins towards the apex, then the G. purpureum is the 
commonest and widest-distributed Indian species. — Dalzell and Gibson alone identify 
a plant with G. purpureum, Br. and I have examined authentic specimens of 
it, which they did not, for they give Brown's characters for the species, whilst 
those of their specimens are what I have given above. G. purpureum is the 
tallest and largest-leaved Indian species; its flowers vary from white veined with 
red-purple to pale purple with stronger veins. 
2. G. dilatatum, Br. in Hort. Kew, Ed. 2, v. 207; leaves usually 
sessile, sepals linear-oblong subacute 3-5-nerved, petals obovate-oblong 
5-7-nerved, lip broadly cymbiform, tip dilated recurved crenulate or un- 
dulate, disk smooth or with granulate nerves ending in irregular small tu- 
bercles. Lindl. Gen. & Sp. Orchid. 175; Lodd. Bot. Cab.t.1797 ; ? Wight

If I am right in respect of this species, it differs from purpureum in its lower 
stature, broader petals and lip, the disk of which is smooth, granulate or subcaruncled. 
Wight's figure is probably an exaggeration of the flowers. Dalzell and Gibson 
describe it as a Concan plant, but I have seen no specimens so named by them.

linear-oblong, petals almost orbicular 7-9-nerved, lip very broad narrowed 
ypvarda from the 2-crested dilated base, disk nearly naked, tip crenulate.

Griffith further describes his G. attenuatum (which is certainly the same as 
Wallich’s candidum) as having a truncate spike, subequal sepals and petals (which 
they are not in his drawing in Herb. Calcutt.), inodorous white wide flowers, less 
Spreading than usual, tip of lip concave, almost conduplicate, emarginate, crenate, 
isk with a callus, column sprinkled with cellular pubescence below the stigma and 
along the broad nerves of the lip, and a very short column with a bidentate tooth on 
each side of the apex.—It is a very distinct species. A single specimen of G. citrinum
