THE DICTIONARY OF GARDENING, 
OSTRYA (the old Greek name used by Theophrastus). 
Hop Hornbeam. Orp. Corylacew. A small genus (two 
species) of hardy deciduous trees, closely allied to Car- 
pinus in foliage, but having the female flowers in terminal, 
_ drooping catkins, each inclosed in an inflated involucre. 
They are inhabitants of North temperate regions, one 
being American. Both the species are best grown from 
imported seeds—for -these do not appear to become 
ripened in this country—or they can be grafted, using 
the common Hornbeam as a stock. Almost any soil will 
suit them. i

Poets Cassia. ORD. Santalacew. A small genus (five 
or six species) of greenhouse evergreen glabrous shrubs, 
natives of South Europe, nearly the whole of Africa, and 
the East Indies. Flowers small, sub-dicecious, peduncled ; 
the males in a few-flowered, lateral raceme; the fertile 
flowers sometimes solitary. Fruit drupaceous, one-seeded, 
crowned by the limb of the perianth. Leaves narrow 
or ovate, alternate, entire, papery or rather thick. The 
undermentioned species, probably the only one intro- 
duced, thrives best in a sandy-loam soil. Propagated by 
cuttings of ripened shoots, inserted under a hand light, 
in spring.

species) of greenhouse or nearly hardy, glabrous shrubs, 
sub-shrubs, or herbs, confined to South Africa. Flower- 
heads yellow or rarely bluish, mediocre or small, peduncu- 
late, corymbosely paniculate or solitary at the tips of the 
branches; involucre campanulate or hemispherical; re- 
ceptacle flat or convex, naked or foveolate. Leaves alter- 
nate or radical, entire, toothed, or dissected, often some- 
what fleshy. Othonnas are of the easiest cultivation; 
they require a thoroughly well-drained, porous soil— 
provided the drainage is perfect, the nature of the 
soil is almost immaterial. They are readily propagated 
by cuttings. The species here described are those best 
known to cultivation.
