ousG bulbous perennials. Offsets. 

 Sandy peat. 



CYPHIA. Five species. Green- 

 house annuals. Seeds. Common soil. 

 C. phyteuma is a tuberous-rooted, and 

 C. cardamincs a stove herbaceous pe- 

 rennial. Young shoots. Peat, loam 

 and sand. 



CYPRESS. Citpressus. 



CYNARA. (See Cardoon and Arti- 

 choke.) Eight species. Chiefly hardy 

 herbaceous perennials. Seeds. Good 

 rich soil. 



CYNIPS. Gall-fly. The species of 

 this genus chiefly confine their attacks 

 to the oak and other timber trees. The 

 species chiefly noticeable by the garden- 

 er is the C. roscE, which causes the hairy 

 galls occasionally observed upon rose 

 trees. 



CYPRIPEDIUM. Lady's slipper. 

 Twelve species, and variety. Chiefly 

 hardy terrestrial orchids. Division. 

 Sandy peat. 



An anonymous writer gives the fol- 

 lowing correct directions for their culti- 

 vation : — 



" The sorts in general cultivation 

 are, Cypripedium venustum (purple and 

 green) ; piii'puratum (purple); insigne 

 (green and purple) ; humile (purple and 

 white) ; guttatum (yellow) ; ventricosum 

 (dark purple); and our own pretty na- 

 tive species, Calceolus (yellow). 



«' or these the three first are from 

 warm latitudes, and consequently re- 

 quire the temperature of a stove ; the 

 remaining sorts come principally from 

 North America, and are either hardy, 

 or require but a moderate protection 

 during the winter and spring. 



"The stove kinds are found to suc- 

 ceed tolerably well by being potted in 

 Boil composed of rotten wood, moss, 

 and a little silver sand; while the 

 hardier kinds thrive best when planted 

 in a shady situation in sandy peat. 



" The American varieties require a 

 protection of straw, or some other ma- 

 terial, to preserve them from the effects 

 of severe frosts, and to throw off the 

 rain in wet seasons. 



" At Messrs. Rollison's, of Tooting, 

 they succeed remarkably well in a peat 

 border adjoining the back wall of a 

 heath house, being covered during the 

 winter and spring months with sphag- 

 num to the depth of two or three inches. 

 Another successful method of treating 

 them, is to pot them in good sized pots, 



in a mixture of sandy peat and rotten 

 saw-dust, keeping them in a cool 

 green-house or frame. 



" They are difficult of increase. They 

 may sometimes be propagated by divi- 

 sion of the roots ; this, however, occurs 

 but rarely. Occasionally, in favourable 

 situations, they will perfectseeds ; espe- 

 cially, if care is taken, when the flowers 

 are in a proper state, to apply the pollen 

 to the stigma with a camel hair pencil. 



" As they are plants which thrive 

 only in shady situations, where the 

 ravs of the sun do not penetrate with 

 sufficient power to cause a spedy eva- 

 poration, but little moisture will be ne- 

 cessary even during the summer, parti- 

 cularly if the soil be protected with a 

 covering of moss; and during their pe- 

 riod of rest in the autumnal and winter 

 months, water may be entirely dispensed 

 with." — Gard. Chron.
