while growing. Propagated by division of the plant. They 

 are closely related to the Arums, a familiar instance of which 

 occurs in the " lords and ladies " of our hedge-banks. There 

 are numerous species in cultivation. 



CALAMINTHA. Calamint. [Labiatae.] Pretty her- 

 baceous perennials. Common soil. Propagated by division, 



CALAMPELIS. [Bignoniaceae.] Handsome free-growing 

 half-hardy climbers, well adapted to cover a considerable space 

 out of doors in summer, or to intermix with other more close- 

 growing species on a trellis. The blossoms are tubular, 

 orange-coloured, in loose panicles, and are very showy. 

 Ptequires protection in winter. Light loamy soil. Propagated 

 freely by seeds. It is sometimes called Eccremocarpiis. 



CALANDRINIA. [Portulaceae.] Pretty herbaceous 

 plants. C. discolor and C. grandifiora are best grown as 

 biennials. C. speciosa and C. procumhens are very pretty 

 treated as annuals, and flower best in diy, hot situations, with 

 their branches trailing over stones. The latter should be 

 sown either in pots during March, to be planted out in May, 

 or in the open border some time in April. The former, if 

 sown about August, and kept over winter in the greenhouse, 

 flower vigorously in the following summer. All like a light 

 soil of sandy loam, peat, and leaf-mould. Seeds are the best 

 means of propagation. They flower best in hot, dry, sunny 

 situations ; in fact, their blooms only expand to the sun, but 

 when expanded their rich purple colour is veiy attractive. 



CALANTHE. [Orchidaceae.] Herbaceous perennials, with 

 very beautiful blossom. Soil, peat and loam, mixed with 

 sand and charcoal lumps, well drained, with plenty of water 

 whilst growing. Increased by division. There are numerous 

 very handsome stove species. 



CALATHEA. [Marantaceae.] C. zehrina is one of the 

 handsomest stove plants in existence in respect to its foliage, 

 which is large, velvety, and beautifully variegated with dark 

 green and a paler tint. It is a perennial, growing freely in a 

 light loamy soil, and increasing by division. The flowers of 

 this species are of a purple colour, and are produced from 

 April to July ; but the leaves are the most conspicuous part. 



CALCEOLARIA. Slipperwokt. [Scrophulariaceae.] 

 Shrubs and herbs, mostly requiring greenhouse protection,
