210 ORCHIDS. 
sepals oblong, white, with a rosy tinge; petals broader, 
white, tipped with amethyst; lip large, spreading in front, 
funnelled behind, and coloured rich maroon, with an orange 
blotch on each side, and a zone of white in front, the tip 
being rich amethyst. It blossoms in May and June, the 
flowers lasting about a fortnight. This popular Orchid 
is easily procured, being imported in large quantities 
annually. It thrives best when grown on. blocks or in 
shallow baskets, or a piece of soft fern stem may be used 
as a block. Whilst growing, it requires plenty of water, 
with a high stove temperature, and from April to September 
it should be syringed overhead at least once a day. In 
October it should be removed to a cooler house, and kept 
on the dry side, but not parched, till it pushes its flower- 
buds. Native of Assam, Bhotan, &c.; introduced in 1856.

D. Farmeri.—A compact, evergreen, upright-growing plant, 
with pseudo-bulbs from rift. to i3ft. high, narrow at the 
base, thickened above, four-angled, and bearing several 
shining dark green leaves 6in. long towards the top. The 
flowers are produced in May, upon long, pendulous racemes, 
in the same manner as those of D. densiflorum, but not so 
closely set together—they are 2in. across; the sepals and 
petals are pale straw-colour, delicately tinged with pink, 
the disk of the lip being golden yellow, and the upper 
surface downy. It is a very beautiful and delicate species, 
and lasts some ten or twelve days in full perfection; the 
flowers are produced at the same time as the leaves, a 
desirable quality which is somewhat uncommon in the 
genus. It is a native of Moulmein and Khasia, and was 
introduced in 1847. It requires the same treatment as 
- D. densiflorum.
