and sphagnum, and suspended near the glass in the 
hottest and moistest stove. It should be kept growing 
till mid-winter, and then rested for about two months. 
This species is peculiar to the forests of Ceylon, where 
it hangs from the trunks of large trees. It is known to 
the natives as the ‘“‘May Flower,” from its time of blos- 
soming. It is said to .be now very scarce in Ceylon. 
Introduced in 1855.

D. moschatum.—A very robust grower, the pseudo-bulbs 
attaining a length of 5ft. or 6ft. and the thickness of a 
man’s thumb. Leaves all along the pseudo-bulbs, ever- 
green, leathery, 5in. long, r4in. wide. Racemes pendent 
from the top part of the older pseudo-bulbs, the same one 
flowering two and even three years in succession; each 
raceme bears from seven to fifteen flowers; sepals 
oblong, pale buff-yellow; petals much broader but simi- 
larly coloured; lip resembling the pouch of a calceolaria, 
downy inside and out, yellow, with two large, deep 
maroon blotches, margined with orange. Each flower 
measures as much as 3in. to 4in. across, and has a musk- 
like odour. Native of Burmah and Moulmein; introduced 
in 1825. This is one of the largest- and most ornamental- 
flowered kinds, but it has the bad character of remaining 
in bloom only a short time—about a week. It should be 
grown in an intermediate house, giving it plenty of water 
in summer and very little in winter. Owing to its size 
and free-rooting nature, it requires a large, well-drained pot 
or pan, and a mixture of peat, sphagnum, and charcoal. It 
blossoms in May or June. Syns. D. Calceolus, D. cupreum.

Var. Calceolaria has slightly smaller flowers, which are 
deeper in colour than those of the type.
