514 FLOWERS OF GARDEN AND GREENHOUSE 
C. ToMENTOSA (hairy). Like C. dayana, but pseudo-bulbs and 
leaves smaller, and flowers coloured pale orange-red, with light streaks 
on the lip; summer. Stove. Borneo, 1854. 
With the exception of the species indicated as suitable 
for block-culture, Calogynes should be grown in pots or 
pans. After attending very particularly to the drainage of these, fill 
up in a conical mound above the rim with a mixture of fibrous peat and 
living sphagnum in equal portions, to which a little silver sand has been 
added. Upon this cone the Celogynes should be planted and pressed 
in firmly, then placed in a dry temperature ranging from 75° to 85° in 
summer, and from 65° to 70° in winter. During the flowering and 
resting periods, however, they will be much better off in a cool house. 
During growth these do not require so much moisture as most Orchids, 
and during the rest they need only sufficient to prevent shrivelling. 
Water should at all times be given to Calogynes with a fine-rosed can, 
and care taken that it does not lodge in the axils, ete.

INDIAN CROCUSES 
Natural Order ORCHIDEZ. Genus Coelogyne 
Sub-genus Pleione 
PLEIONE (Greek, pleion, a year, in allusion to the annual duration of 
the pseudo-bulbs). For garden purposes it is better to keep these 
separate from Calogynes, although botanists have united them. Pleiones 
are alpine plants growing on moss-covered tree-trunks or rocks at an 
elevation of from 3000 to 10,000 feet on the Himalaya. They have 
annual fleshy pseudo-bulbs, more or less flask-shaped and mottled. 
The leaves, which are lance-shaped, plaited, and from 6 to 9 inches long, 
fall off before the flowers develop. The flowers spring singly or in pairs 
from the base of the pseudo-bulb; they are large, with long spreading 
petals and sepals, and an oblong many-keeled fringed lip. 
PLEIONE HUMILIS (dwarf). With bottle-green ribbed 
pseudo-bulbs, and flowers 3 inches across, white, with 
lines and blotches of amethyst purple on the lip; January. Intro- 
duced from Nepaul, 1866. 
P. LAGENARIA (bottle-shaped). With depressed irregular pseudo- 
bulbs, dull green mottled with brown, and flowers 3 inches across, rosy 
lilac, the lip striped and blotched with PaEwie margin white ; Noveroet- 
Introduced from Khasia, 1856.
