Cirrhopetalum 



Citharexylum 



each a solitary, ribbed leaf ; the flowers are inter- 

 esting by reason of the long column. Plant in 

 pots or baskets in peat and sphagnum, and place 

 in a warm house, where the atmosphere is always 

 moist.

CIRRHOPETALUM. 



Although the large natural order Orchidacerc 

 contains many genera remarkable for peculiar 

 flowers, few are so curious as the Cirrhopetalums. 

 The genus consists of about fifty low-growing, 

 rhizomatous plants, mostly from the East Indies. 

 Usually the flowers are borne in small umbels, and 

 their chief attraction lies in the connate (joined) 

 lateral sepals. The petals are small, but often 

 end in a tuft of silky, hair-like processes, that 

 are moved by every passing air current. Under 

 cultivation the species need a stove temperature, 

 and grow best in shallow Teak baskets or on 

 blocks or rafts, planted in a mixture of peat 

 and live sphagnum. Nothing in the way of 

 ' drying-off " must be practised, though during 

 the winter much less water is needed than 

 in summer. Cirrhopetalums like abundance of 

 light, and if shaded less than has hitherto been 

 the practice they would flower freely. So far the 

 hybridist has left this genus severely alone.

CISSAMPELOS. 



A genus (nnl. Menispermacea;) of twining plants 

 that flourish in the intermediate house or stove. 

 A compost of peat and loam is suitable, and cut- 

 tings of firm wood root in sand under a bell-glass 

 with bottom heat.

CISSUS. 



A genus (ord. Ampelidea;) of climbing plants of 

 little horticultural value, except discolor, which is an 

 old-fashioned plant that has decidedly handsome 

 Icavi's. and is worthy of a. place in the stove. 

 The plants flourish in fibrous peat and loam with 

 sand, and may be propagated from cuttings in 

 sand beneath a bell-glass, in either the stove or 

 greenhouse, according to the species. The entire 

 genus produces green or greenish flowers, and. 

 strictly speaking, should now be referred to Vitis. 

 The name so well known to gardeners is retained 

 in this cnse for horticultural reasons, but it only

Principal Species :

 Vitis discolor.) 



CISTERNS. 



A cistern should be found in every garden, and 

 the rain-water from greenhouses, and buildings 

 generally, conducted into it, a small portable 

 pump being used to pump the water into smaller 

 tanks as these need replenishing. Feed cisterns 

 are fitted to garden boilers, and if not of the self. 

 fdling kind their replenishing should be entrusted 

 to a responsible person, otherwise a cracked boiler 

 may easily result. A piece of perforated zinc fixed 

 over the supply pipe at the bottom of the feed 

 cistern will prevent large substances of any sort 

 entering and blocking the pipe. 



CISTUS. (ROCK ROSE.) 



Description. Very beautiful hardy or half-hardy 

 shrubs (ord. Cistineae), which cover themselves 

 with pretty flowers in summer. The greater 

 number require a warm position in this country, 

 and it is wise to keep a plant or two in a frame for 

 stock in case of the loss of the others in a severe 

 winter. In the south of England and Ireland, 

 however, several are quite hardy. Among the 

 hardiest elsewhere are ladaniferus and laurifolius. 

 There is a great discrepancy in the nomenclature 

 of the Cistuses, and for the convenience of 

 growers the names in current use have been re- 

 tained. 



All flower about June, unless otherwise stated. 



Propagation. By seeds sown in March or April, 

 under glass, the seedlings being pricked out into 

 a frame or pots. Also by cuttings and layers, the 

 former, about 4" long, under a hand-light or bell- 

 glass in May or early autumn, the layers being 

 made when the plants have gone out of flower. 



Soil. A dry, sandy soil, with a little peat or 

 leaf mould, is best. Heavy soil may be lightened 

 with sand and leaf soil. 



Other Cultural Points. The plants ought always 

 to be sheltered from cold, cutting winds, and 

 severe spring frosts must be guarded against as 

 far as possible.
