CfsUopsis. 

 C. hyacinthosma {Rchb. /.). — Flowers white; point of the 

 superior sepal, and of the petals, orange, with a deep crimson 

 blotch in the middle ; peduncles arising from the base of the 

 well-sheathed bulb, and carrying a dense raceme of six to eight 

 flowers, which have a most delicious Hyacinth-like scent. Panama, 

 1871. 



C(ELOQYNE. 



Dr. Lindlc}- established this genus in 1S25, the first species 

 described being the well-known C. cristata. It is of the tribe 

 EpidcndrccE, and the name is derived from koilos, hollow, and 

 gyne, a pistil ; in allusion to the female organ. The numerous 

 species are confined to the tropical and sub-tropical parts 

 of Asia. They are all epiphytes, with two-leaved, often 

 very thick, angulate-ribbed, or sub-terete, pseudo-bulbs. 

 As a rule, they have large, coloured, membranous flowers, 

 with converging and slightly-spreading sepals, petals of like 

 nature, but narrower, a great hood-like lip, usually bearing 

 fringes on its veins, and a broad, membranous column. 

 About sixty species have been described, many of which 

 are in cultivation, and are deservedly held in high esteem. 

 Those selected are most suitable for the amateur's col- 

 lection, and with ordinary care will grow and flower freely. 

 With few exceptions, these are what may be termed inter- 

 mediate-house plants ; for, although they like a somewhat 

 higher temperature during the growing season, they remain 

 healthier, and flower more abundantl}', if kept in such a house 

 during the resting and flowering time. 



Culture. — Basket- or pot-culture is suitable for most of these 

 plants. In preparing the pots for Ccelogynes, good drain- 

 age must be provided, as they require and enjoy an 

 abundant supply of water during the growing season, 

 though nothing stagnant or sour must be allowed to 

 remain about the roots. For soil use about equal parts 

 of living sphagnum and fibrous peat, with the addition 

 of a little silver -sand. The plants should be raised 

 upon a moderate-sized cone above the rim of the pot, 

 and the soil firmly pressed about them. The time for 

 re-potting or top-dressing Ccelogynes is just after the 

 flowers are past ; and as most of the kinds bloom during 

 winter, re-potting is best done in the spring. Those species
