THE DICTIONARY OF GARDENING, 
Imantophyllum—continued. 
described below are so well known in gardens under the 
name here given, the genus Imantophyllum is retained. 
The species are exceedingly ornamental plants for green- 
house decoration in spring and summer. They may be 
propagated from seed; but, as the production of seed 
has such a weakening effect on the plants ripening it, 
this method is not generally practised. The usual mode 
is to propagate by divisions or offsets, secured when 
repotting the old plants. Unless very small, they should 
be inserted at first in 5in. pots, so that they can remain 
for a year without further disturbance. The roots are 
large and fleshy, and become so thickly matted together 
in established plants that it is difficult to separate them. 
Imantophyllums succeed best in soil composed chiefly 
of fibry loam, with some leaf mould and charcoal added. 
A little crushed bone or bone dust is sometimes inter- 
Imantophyllum—continwed. 
I. Gardeni (Garden’s).* fl. reddish-orange or yellow; perianth 
2in. to 3in. long, curved downwards; scape as long as the leaves, 
with an umbel of ten to fourteen flowers. Winter. i. narrow, 
lft. to 2ft. long, distichous, arching, deep green. Natal and 
Transvaal, 1862. (B. M, 4895, under name of Clivia Gardenii.) 
I. miniatum (brick-coloured),* fl. fine deep orange, lower part 
deep buff, anthers and style bright yellow; perianth about 2in. 
long, somewhat vase-shaped ; umbel large, ten to twenty-flowered. 
Spring and summer. J. ligulate, acute, distichous, lft. to 2ft. 
long, iroadiy sheathed at the base, deep green. h. lft. to 2ft. 
Natal, 1854. See Fig. 284. (B. M. 4783.) I. m. splendens is a fine

- mixed, with good results, as the plants seldom need re- 
potting when once established. They may be grown 
to flower in pots ranging from 5in. to 10in. in diameter, 
according to the strength of the different plants. 
Syringing and any amount of water may be applied in 
summer, when new growth is being made; and a tem- 
perature of 50deg. to 60deg., with air in spring and 
summer, will be sufficient. In winter, less water should 
be given, and a season of rest allowed, by keeping the 
plants quite cool. Good drainage must be insured 
when potting; and an annual top-dressing of rich soil, 
applied to old plants, in spring, will be preferable to dis- 
turbing their roots.- Imantophyllums keep in flower a 
long time in a cool greenhouse. 
I; Aitoni (Aiton’s). A synonym of Clivia nobilis. 
-L oyrtanthifiorum (Cyrtanthus-flowered). fi. clear rich salmon
