been deeply dug and is well-drained 

 in consequence. They are quite 

 hardy in most places, and are easily 

 increased by offsets from the older 

 bulbs. 



CHLOROSPATHA (rhloros, green ; 

 spathe, spathe ; in reference to the 

 colour of the spathe). Nat. Ord. 

 Aroideae. — A genus with only one 

 species— 



C. Kolbi.— A native of Colombia, 

 having a tuberous root-stock, large 

 green leaves with spotted stalks, and 

 cylindrical greenish spathes (Gartenji. 

 t. 933). 



This species requires to be grown 

 in plenty of heat and moisture in the 

 same way as Alocasias and other 

 tropical Aroids. It is not of much 

 ornamental value, however. 



CISSUS (kissos, Greek name for the 

 Ivy, in reference to the habit). Nat. 

 Ord. Ampelidese. — A genus closely 

 related to Ampelopsis, and containing 

 several ornamental-leaved plants, the 

 best known being the fibrous-rooted 

 C. discolor. A little-known species 

 with tuberous roots is — 



C. adenopodus, a native of Uganda, 

 with climbing stems and tendrils, and 

 leaves consisting of three ovate, 

 pointed and coarsely toothed leaflets 

 of a bright red, like the young shoots. 

 The small flowers are borne in flat 

 panicles. (Keiv Bulletin, 1906, 247.) 

 This species may be grown in a stove 

 house in the same way as C. discolor, 

 in a mixture of turfy loam, with a 

 little peat or leaf -soil, and some coarse 

 sand added. 



OLAYTONIA (after John Clayton, 

 who collected plants in Virginia). 

 Nat. Ord. Portulacese. — A genus con- 

 taining about twenty species of plants, 

 some of which referred to below have 

 tuberous root-stocks. 



C. sibirica. — A Siberian perennial 

 with spindle-shaped root-stocks, ovate 

 leaves, and rosy flowers with lobed 

 petals {Bot. Mag. t. 2243). 



C. virginica (C. graiuliflora). — A 

 dwarf -growing native of N. America, 

 with linear lance-shaped leaves, and 

 white flowers with notched petals 

 {Bot. Mag. t. 941). 



These species flower early in the 

 year, and should be grown in warm 

 sunny spots in the rockery or border. 

 They are quite hardy, and may be 

 increased by division of the root- 

 stocks in early autumn, or from seeds. 



CLIVIA (after a member of the 

 Clive family). Nat. Ord. Amaryllidese. 

 — A small genus of herbaceous plants 

 having imperfect bulbs consisting 

 only of leaf-bases, but having very 

 stout root fibres. The strap-shaped 

 leaves are arranged in two rows 

 (distichously), and are deep green 

 and ornamental in appearance, and 

 leathery in texture. The scentless, 

 more or less erect, funnel-shaped 

 flowers are borne in umbels on top 

 of a stout peduncle. The following 

 are the only kinds known, often under 

 the name of Imantophyllum : — 



C. cyrtanthiflora. — This is con- 

 sidered to be a hybrid between G. 

 nohilis and G. miniata. The droop- 

 ing tubular flowers of a beautiful 

 salmon-red are borne in large clusters 

 during the winter and early spring 

 months {Fl. d. Serr. t. 1877). 



C. Garden!. — This species from the 

 Transvaal and Natal is often called 

 G. Gardneri. It was named after 

 Capt. Garden, Avho introduced it in 

 1855. The bright green leaves are 

 li to 2 ft. long, and the orange-red 

 or yellow flowers with green tips are 

 borne in umbels of twelve to twenty 

 on stalks as long as the leaves, during 

 the winter months from December to 

 February. (Bot. Mag. t. 4895.)
