AN ENCYCLOPADIA

Iostephane—continued. 
tuberous root during severe frosts. Propagation may 
be effected by division; or by seeds, sown in spring. 
I. heterophylla (various-leaved). l.-heads nodding ; ray-florets 
lilac, fifteen to twenty, neuter, many-nerved, ad +3 hairy 
beneath, obtusely tridentate at apex ; disk -florets herma; hrodite, 
funnel- -shaped ; receptacle —— conical; peduncles elon: 
ge one- flowered, densely pilose, simple at apex. Autumn. 
radical ones numerous, Grating petiolate, oblong, acute ; 
base acuminate ; margin serrate ; cauline leaves very few, lanceo- 
late ; superior ones linear- lanceolate, acuminate, entire, sessile. 
Stems pubescent, clammy. h. lift. 1829, (S. 'B. F. G. ser. ii., 
52, under name of Echinacea heterophylla.) 
IPECACUANHA. The root of Cephaélis Ipeca- 
cuanha, a Brazilian plant, the cultivation of which has 
been introduced into India. The roots afford the im- 
portant emetic, 
dysentery. 
IPOMERIA. Now included under Gilia. 
IPOMGA (from Ips, Bindweed, and omoios, similar, 
because of the close resemblance of this genus to Convol- 
vulus). Including Batatas, Calonyction, Exogonium, Phar- 
bitis, and Quamoclit. ORD. Convolvulacew. An extensive 
genus (over 400 species have been described) of stove 
or hardy, evergreen or deciduous, twining or creeping herbs, 
rarely shrubs, widely distributed over all warm 
with a few species extending into North America. Flowers |. 
purple, violet, scarlet, pink, blue, or white, rarely yellow, 
often showy ; corolla salver-shaped, campanulate or 
tubular; limb spreading, entire or angular. Leaves 
alternate, entire, lobed, or divided. Some of the stove 
—— of Ipomea are among the prettiest of plants for 
ering trellises or pillars, particularly over paths, where 
beautifully-coloured flowers may be seen to advantage. 
y are of free growth, and like plenty of root room, such 
as may be secured by planting in a border inside the house. 
If this is impracticable, large pots or boxes must be sub- 
stituted. The hardier kinds succeed in the open air during 
summer, if forwarded a little in a warm frame, and after- 
wards planted out in sheltered positions. All the annual 
species, whether stove or half-hardy, may be readily raised 
from seed, which should be sown early in spring, in a warm 
house. A good plan is to place two or three seeds each 
in small pots, and afterwards transfer the plants bodily 
into larger sizes. ‘They should be trained on small 
temporary stakes until established or finally planted out. 
A suitable compost consists of fibry loam, rotten manure, 
and leaf soil, which should be mixed together and used
