Cystacanthus 



CYRTANDRA. 



A largi' genus (tir/l. Gesneracese) of stove shrubs 

 :md trees. They are of little value hortieultnrally. 

 aii<l few species have, so far, been introduced. 

 They like a mixture of rough peat in bulk, with a 

 littk 1 sphagnum. san<l. and charcoal ; also plenty 

 of water when growing, and brisk heat; no water 

 in winter. They may lie reproduced by half- 

 ripened cuttings, in heat, in spring. 



Principal Species : 



bicolor, wh., pur. Pritchardii, wh. . small, 



pendllla, wh., s]iotted jiur. 



CYRTANTHERA (nee JACOBIXIA). 



Other Species and Varieties :

 CYRTANTHUS. 



Handsome Smith African bulbous plants (tirtl. 

 Amai'vllidese), with pretty flowers, and of much 

 value for flowering in the greenhouse, or for con- 

 servatory decoration Propagation is by offsets. 

 A rich, open loam suits. A greenhouse temperature 

 in summer suits the greater number, but the 

 majority ought to be kept in the stove in winter. 

 After the leaves become yellow, keep them dry 

 until spring, when the plants start into growth. 

 Some, e.g. c.arneus, are evergreen, and must be 

 carefully watered in winter.

CYRTOPERA. 



Greenhouse terrestrial Orchids (ord. Orchidaceas), 

 closely allied to Cyrtopodiuru, and sometimes 

 placed under that genus. Propagation, by division 

 before growth starts. Soil, good loam two-thirds, 

 old Mushroom bed manure one-third, with sand. 

 Tlie plants love plenty of heat and moisture in the 

 growing season, and less water and a lower tem- 

 pi-rat nre in the resting period, which coincides 

 with our winter.

 must he kept close, but watched, or they damp off.
