GENERA AND SPECIES gl 
house. C. falcata, red, C. macroplectron, pale rose ; spotted ; 
and C. sheciosa, scarlet, are the best species. 
Colax.—A small genus of cool-house Orchids allied 
to Lycaste, and requiring similar treatment. C. jugosus has 
been crossed with Zygopetalums with good results. 
Coryanthes.—These are similar in habit to Stanhopea. 
The plants should be grown in baskets suspended in the 
intermediate house. The structure of the large, fleshy 
flowers is most remarkable, and some interesting particulars 
relating to their fertilisation by insect aid have been re- 
corded in the Gardeners’ Chronicle (July 17, 1897, p. 31). 
Cycnoches.— Of similar habit and requirements to 
Catasetum. The plants are best grown in baskets and sus- 
pended. They should be rested cool and dry with the 
deciduous Dendrobiums. C. chlorochilon (Swan Orchid), C. 
Egertonianum, C. Loddigesti, C. maculatum, C, pennnanuns, 
and C. pentadactylon are fine species. 
Cymbidium.—These are showy, large-growing Orchids 
for the intermediate house or warm conservatory. Pot 
the plants in equal proportions of fibrous loam, peat, and 
Sphagnum-moss. C. giganteum, C. Lowianum, C. grandi- 
florum, and C. Tracyanum are the most commonly grown. 
C. eburneum, C. Mastersii, C. insigne, and C. erythrostylum 
are fine, white species, the latter two with rose markings on 
the lip. There are numerous hybrids. C. Lowio-eburneum, 
a cross from C. Lowianum, and C. eburneum is illustrated in 
Plate VI. 
Cynorchis.—Terrestrial Orchids from Tropical Africa 
and Madagascar, requiring to be grown in the warm house 
in moist and shady conditions. The flowers are generally 
of rose colour.
