312 MR. HENRY RIDLEY ON ORCHIDEZ AND 
In long grass it often attains a considerable size. Mr. Hallett 
saw a plant over 6 feet tall in Lingga. These large forms 
usually have broad plicate leaves somewhat resembling those 
of Curculigo recurvata, whence the natives of Sungei Ujong call 
it “Poko Lumbah Tikus,” Lumbah being the native name for 
Curculigo. “ Tikus” (mouse) means that it is not so large as 
that plant. On damp rocks by streams it is often much smaller, 
with much narrower grassy leaves, but there are many inter- 
mediate forms. 
A more distinct form is the variety alba, which has the 
flowers and bracts pure white; I have met with it at Pulau 
Sembilai, in the Dindings, also at Tjiboddas, in Java. This 
variety is very local, and, as far as I have seen, does not occur 
with the purple form. 
The typical plant is not “lilac,” as mentioned in the ‘ Flora of 
British India,’ but of a purplish crimson: flowers and bracts 
being all of the same colour, except the yellow spot on the lip. 
As described by H. O. Forbes (‘ Naturalist’s Wanderings,’ 
p. 89), the flowers are constantly self-fertilized, although they 
are brilliantly coloured, and are, when the blossoms first open, 
quite fertilizable by insects.

This is common on the open “stone-fields” (Padang Batu of 
the Malays), on the granite hills at from 2,0CO feet upwards, 
growing usually in spots where water trickles. 
S. Wrayi, Hook. f., is merely a full-sized form of a strong 
plant. It invariably grows with the small form, and is the 
variety most sought by the orchid dealers. The flowers are 
often even bigger than in the figure in the ‘Icones Plantarum, 
and are of a richer orange than the small flowered form. The 
scape often attains the height of 4 feet.
