250 ORCHIDS. 
sheathing leaves, 14}ft. to 2ft. long. The flower-scape is 
from 5ft. to 6ft. high, and erect. The flowers are 6in. 
in diameter, the sepals and petals being broadly oblong, 
wavy at the margin, and of a rich yellow ground-colour, 
blotched and spotted with reddish purple; the lip, which 
is three-lobed and comparatively small, is yellow, streaked 
with brownish red. A native of Java, Singapore, Cochin 
China, &c.; introduced in 1837. This gigantic Orchid 
cannot be successfully grown unless placed in a very hot 
stove, in full sunshine, and with the atmosphere kept 
constantly saturated. It was first flowered in the once 
famous nurseries of Messrs. Loddiges, of Hackney, and 
again by the late Mr. Day, of Tottenham; but in both 
cases the flower-spike was small, and it was developed 
very shortly after the plant had arrived in this country. 
Mr. Day, who had seen it growing in all its native luxuriance 
at Singapore, recommended the treatment here advised, 
which is being tried for some plants of this Orchid now 
in the Kew collection. The roots of this species some- 
times grow erect, and develop short, spine-like rootlets, 
which, when dry, are as hard as thorns. All the Grammato- 
phyllums appear to have the habit of developing these 
upright or heliotropic roots.
