88 PRESENT-DAY GARDENING 
impatient of a close atmosphere, and therefore the proper 
ventilation of the house in which they are grown is an 
important matter. C. Triane, var Hydra, is illustrated in 
Plate IV. 
Chysis.—A small genus of intermediate-house epiphytes, 
comprising C. bractescens, white; C. aurea and C. levis, 
yellow and red ; C. Limminghei, and several hybrids. 
Cirrhopetalum.—A section of Bulbophyllum, of similar 
habit, and requiring similar treatment. The curiously 
formed flowers frequently have the upper segments fringed, 
and the lateral ones approached and continued into slender 
tails. 
Cirrheza.—Allied to Gongora, and requiring similar 
treatment. 
Cochlioda.—A compact-growing genus to be grown 
with the Odontoglossums. C. Noezliana, scarlet, has been 
a fine species in the hands of the hybridiser, and in the 
future may give us “Scarlet Odontoglossums.” C. vulcanica 
has deep rose-coloured flowers. 
Ceelia.—There are several species of Ccelia, and they 
require to be grown in the intermediate house. 
Ceelogyne.—A very large genus of two distinct sections, 
that represented by C. cristata being evergreen ; the Pleione 
or Indian crocus section deciduous, and requiring to be 
treated as terrestrial Orchids, while the larger section are 
epiphytal. The epiphytal sections are warm and _ inter- 
mediate house plants. The Pleiones should be grown in a 
cool house, and rested quite dry after the leaves fade and 
until growth again commences. 
Comparettia.— These are small-growing epiphytes. 
Grow in small baskets or hanging pans in the intermediate
