48 GLENNYS HANDBOOK 



CALOSTEMMA. [Amaryllidacese.] Pretty greenhouse 

 bulbs. Soil, sandy loam, with decayed manure and leaf- 

 mould, made free by about one-eighth of gritty sand. The 

 plants may be rested in a cold pit free from frost during 

 winter, and in spring excited in a warm pit or greenhouse. 

 Propagated by offsets. The best are C. album, white, and C. 

 purjmrewn, purple. 



Cx^LOTHAMXUS. [Myrtaceee.] Beautiful evergreen 

 greenhouse shrubs, allied to Callistemon, and requiring the 

 same kind of management. 



CALTHA. Marsh Marigold. [Pianunculacese.] Hardy 

 perennial water plants, of easy culture, propagated by dividing 

 the roots. They are suited for planting on the margin of a 

 piece of water, where their bright-coloured blossoms are very 

 sho^vy. The most ornamental is the double-flowered variety 

 of our wild species [C. ;palustris flore-pleno). Though growing 

 best in the immediate vicinity of water, and most appropriate 

 for rough sceueiy, they do very well in other situations if the 

 soil is damp : and the variety above named is sufficiently 

 showy to make it worth introducing among hardy perennials 

 in a mixed border. 



CALYCANTHUS. Allspice. [Calycanthaceae.] Hardy 

 deciduous w^all shrubs, remarkable for the fragrant spice-like 

 odour of their brow^nish blossoms. Moist, light, loamy garden 

 soil. Increased by layers. The best are C. fioridus, C. 

 fragrans, and C. lutea. 



CALYSTEGIA. Bearbind. [Convolvulace^.] Convol- 

 vulus-like twining or trailing perennial plants, hardy, or 

 mostly so. Their culture is extremely simple : a fragment 

 of the perennial root merely requires to be placed in the 

 ground, and it will soon establish itself, and if not checked, 

 spread and become a troublesome weed. Sandy loam is most 

 congenial to them. C. soldaneUa should be occasionally 

 watered with salt water, and C. jiuhescens (double) is worth 

 a place. 



CALYTHPiIX. [Chamaelauciaceae.] Elegant greenhouse 

 evergreen shrubs. Soil, peat with one- third sandy loam. 

 Propagated by cuttings in sand, under a bell-glass. C. glabra 

 and C. virgata flower white. 



CAMASSIA. [Liliacese.j A strikingly handsome hardy
