CENTRONIA. 



A .small genus (nnl. Melastomacese) of orna- 

 mental shrubs, propagated by cuttings under a 

 bell-glass, and thriving in a mixture of two parts 

 of peat, line part of leaf mould and sand. 



Principal Species :

CENTROPETALUM. 



A most interesting little genus (ord. Orchidaceaj) 

 of epiphytic Orchids from the mountains of tropi- 

 cal America. Not being so plentiful or showy as 

 some Orchids, they are seldom met with in cultiva- 

 tion. An intermediate temperature and the usual 

 compost of peat and sphagnum suit them. 



Principal Species :

CENTROPOGON. blownish 



Effective stove and greenhouse plants (ord. Cara- 

 panulacete) of much beauty and interest. Flowers 

 like those of the Lobelia. The hybrid lucyanus is 

 the most desirable. Propagated by cuttings of 

 the young shoots (preferably with a heel) rooted in 

 sandy soil under a bell-glass, with a bottom heat 

 of not less than 60; also by division. Sandy 

 fibrous peat and loam. Grow in a cool stove or 

 warm greenhouse until they come into bloom, 

 when the plants may be placed in a house with a 

 temperature of not less than 50. After flowering, 

 replace in their former quarters.

CENTROSEMA. 



The few members of this genus (<ird. Legumin- 

 osa>) are stove climbers with evergreen foliage, and 

 may be propagated from seeds or cuttings and 

 grown in any good, well-drained compost.

CEPHAELIS (yn. CEPHAI.EIS). 



A genus (nrrl. liubiacete) of stove plants, from 

 one species of which, Ipecacuanha, we get the well- 

 known ipecacuanha of commerce. The plants grow 

 well in a mixture of turfy loam, fibrous peat, and 

 sand, and may be increased from cuttings in sand, 

 under a bell-glass in bottom heat.

CEPHALANTHERA. 



Terrestrial Orchids (ord. Orchidacea:), all native* 

 of Great Britain, and consequently quite hardy ; but 

 the genus is also represented in other countries. 

 They are, however, difficult to establish in gardens, 

 unless removed while at rest and planted in a 

 mixture of peat and loam.

CEPHALANTHUS. (BUTTON WOOD.) 



North American and South African hardy or 

 tender, deciduous or evergreen shrubs (ord. Kubi- 

 aceas). The only hardy species readily available 

 is occidentalis, which is about 7' high, and has 

 whitish flowers at the ends of the branches in July 

 and August. It is propagated by layers, and also 

 by cuttings under glass in autumn. It grows in 

 common soil, but likes that which is moist and 

 peaty. 



Principal Species:

CEPHALARIA. 



Hardy annual or perennial herbs (ord. Pipsacese), 

 of rather coarse and ungainly habit ; hence suit- 

 able rather for the wild garden than the herba- 

 ceous border. They may be easily raised from 

 seed, sown either when it is ripe or in spring 

 outdoors. Any ordinary soil will do

CEPHALOTAXUS. 



Pretty, Yew-like evergreen Coniferous shrubs 

 or trees (ord. Conifera;), which may advantageously 

 be used in gardens and pleasure grounds. Several 

 species have been described, but, according to the 

 " Manual of the Conifero," they are not differen- 

 tiated by very definite characters. In this country 

 they seldom exceed 20' in height, and the stature 

 named below is that usually attained. Propagated 

 by seeds, sown in spring, or by cuttings in sandy 

 soil in a cold frame in August or the following 

 month. Almost any well-drained soil. 



Principal Species : 



drupacea, 5', Ivs. grass grn., fruit over 1" long, 

 chestnut br. 



Fortuni, 8', Ivs. dark grn., fruit more than 1" long, 

 dull br. The Index JCen-enxis refers it to drupacea, 



pedunculata, 8', Ivs. larger and darker than 

 those of drupacea, fruit on a short stalk (syn. 

 Taxus harringtoniana). The vars. fasligiata and 

 spha;ralis are grown, the former being very peculiar 

 and interesting (.<//. of fastigiata, Taxus japonica 

 and Podocarpus koraianus). 



CEPHALOTUS. 



A dwarf-growing, pitcher-bearing plant (ord. 

 Saxifrages;) from King George's Sound. It is n 

 most interesting plant, and might well find a place 

 in every greenhouse. It is a herbaceous perennial, 

 aud may be multiplied from offsets. The compost 

 may consist of chopped sphagnum and fibrcms peat, 

 intermixed with potsherds. The pots or pans must 

 be perfectly drained, and careful watering is
