CYNOGLOSSUM. Hound's Tongue. [Boraginaceae.] A large 

 genus of hardy annuals, biennials, and perennials, generally 

 coarse-growing, and not desirable. C. canescens, diffiisum, 

 hirsutum, and lanceolatum, are annuals ; C. amplexicaule, an- 

 chusoides, Australe, grandiflorum, longiflorum, Magellense, to- 

 mentosum, and Virginicum, are perennials; and there are 

 about twenty biennial species. 



CYPRESS. See CUPRESSUS. 



CYPRESS VINE. See QUAMOCLIT. 



CYPRIPEDIUM. Lady's- Slipper. [Orchidaceae.] Beautiful 

 herbaceous perennials, comprising about a dozen hardy and 

 some two dozen stove species. The latter are easily culti- 

 vated in a moist heated atmosphere, such as the Orchicl- 

 eous family generally require, and may be potted in rough 

 turfy peat. They must not be over-watered at the root, nor 

 should cold water be poured about their roots or hearts at 

 any time. They increase by division. The hardy ones are 

 more difficult to cultivate, and can only be well managed in 

 a cold, shady situation, in a bed of peat earth. They may be 

 kept in pots of peat soil, and set into a frame. Whether 

 grown in pots, or planted out, they do not at all like to be 

 disturbed, and should therefore be replanted or repotted as 

 seldom as possible. It is a remarkable as well as beautiful 

 family, and is worth any trouble to secure its successful cul- 

 tivation.
