 of stove Palms, with large fan-shaped leaves. Trunks 

 ringed or channelled, unarmed, generally very straight, 

 terminated by a crown of leaves, with prickly petioles. 

 They are of somewhat slow growth, and are best cultivated 

 in a compost of two parts loam, one of peat, and one of 

 sand. Thorough drainage and a liberal supply of water 

 are essentials to success. See also Chanuerops, Livis- 

 tona, and Sabal.

 by the natives for thatching, making baskets, Ac.

 plaited, forming a complete circle about 12ft. hi diameter ; petioles 

 about oft. long ; edges armed with small brown teeth-like spines. 

 h. 100ft South India and Ceylon, 1742. The famous Talipot 

 Palm, whose magnificent leaves are used in making fans, 

 umbrellas, and many other things. 

 Other species are : elata, macropoda, sylvestris, and Taliera. 



COR.YSANTHES (from korys, a helmet, and anthos, 

 a flower; flowers helmet-shaped). SYN. Calcearia. OBD. 

 Orchidece. A genus of small, but very pretty, greenhouse 

 terrestrial Orchids, allied to Pterostylis, and requiring a 

 compost of light sandy loam. There are about fifteen 

 species, distributed throughout Australia, New Zealand, 

 and the islands of the Malayan Archipelago, but they are 

 rarely seen in cultivation. 



C. limbata (edged). fl. purple, white. Autumn. I. ovate, cor- 

 date, bright green, with reticulated white veins, h. 2in. to Sin. 

 Java, 1863. (B. M. 5357.)

COSCINIUM (from koskinon, a little sieve ; alluding 

 to the seed being pierced). SYN. Pereira. OBD. Meni- 

 spermacece. A stove climbing shrub. It requires plenty of 

 room to grow in, or it will not flower well. A compost of 

 light loam and peat suits it well. Cuttings of young 

 growth, taken during summer, will root under a hand 

 glass. 



C. fencstratnra (window-wood). False Calumba. fl. greenish ; 

 peduncles umbellulate, several from the same bud. November, 

 t. alternate, cordate, entire, five to seven-nerved, smooth and

COSMANTHUS (from kosmos, beautiful, and anthos, 

 a flower). A small genus of annual herbs, belonging to the 

 natural order Hydrophyllacece, but now usually included 

 under Fhacelia (which see). 



COSMELIA (from kc.smeo, to adorn ; in allusion to the 

 beauty of the flowers). OBD. Epacridece. An erect much- 

 branched greenhouse evergreen shrub. It requires peat, 

 with a large proportion of silver sand ; in fact, the same 

 treatment as Epacris (which see). Cuttings may be ob- 

 tained during the summer months. 



Cosmelia continued.

 elongated tube, and a five to six-lobed spreading limb. 

 They are of easy culture in a compost of loam, leaf mould,

 wood, placed in sand, under a hand glass, in bottom heat. 



C. obtusifolla latifolia (broad obtuse-leaved).* fl. white, very 

 fragrant, disposed in terminal cymes ; peduncles stout, Jin. to 



jin. long ; tube Sin. long, somewhat dilated for iin. at the throat.

COSMOS (from kosmos, beautiful ; in reference to the 

 flowers). OED. Composite. Annuals or perennials. Flower- 

 heads solitary; receptacle furnished with linear acute, 

 coloured bracteoles, equalling or excelling the florets. 

 Leaves pinnate. All are readily increased from seed, which 

 may be sown in gentle heat, in early spring. When large 

 enough, the seedlings should be pricked off, and finally 

 planted out in May, similar to other annuals. The perennials 

 require to be protected during winter, and may be pro- 

 pagated like Dahlias, in spring. 



FIG. 534. FLOWERING BRANCH OF COSMOS BIPINNATUS. 



C. blpinnatUS (bipinnate). fl.-heads rose or purple, with a yellow
