OSIER. Any of the Willows that are grown for the 
sake of their long, flexible shoots, which are largely used 
for basket-making, &c.—and almost any of them may be 
turned to this account—are called Osiers. Some of the 
species, however, are much superior to others, and pro- 
bably the one most extensively grown for the purpose 
above indicated is Salix viminalis. Though this is a 
moisture-loving plant, it will not succeed in ground 
charged with stagnant water; and if it is desired to grow 
it, with a view to profit, the ground should be drained 
to a depth of 18in. or 2ft. Open drains, about 1ft. in 
width, will do, but these must always be kept clear. 
Trench the land 1ft. or so in depth, and insert the 
cuttings, in rows, 18in. apart, allowing a 
Space of 12in. in the rows. February is, 
probably, the best time for planting. An 
acre of land will take about 28,000 cut- 
tings. Cut the shoots—not later than 
February—as close to the ground as 
practicable, and keep down weeds by 
hoeing, &c. If these are allowed head- 
way, the Osier crop will be materially 
affected. 
O. stellata (starred). f. corymbose; calyx tube elongated; 
~ OSKAMPIA. A synonym of Non- 
nea (which see). 
(from osme, perfume, 
and anthos, a flower; in allusion to the 
ce of the flowers). ORD. Oleacee. 
A small genus (about seven species) of 
hardy, or nearly hardy, glabrous shrubs 
or trees, natives of North America, 
Eastern Asia, and the Pacific Islands. 
Flowers small, disposed in short, rarely 
branched, axillary fascicles or racemes ; 
lobes of corolla four, imbricated. Drupe 
ovoid or globose. Leaves opposite, ever- 
green, entire or dentate. For culture, 
see Olea (under which the species are 
Sometimes classified). 
O. americanus (American). fl. in threes, 
almost sessile; thyrse rather compound, 
axillary, narrow. June. Fr. purple, globose, - 
containing an edible nut. 1. elliptic-lanceo- 
late, about 4in. lo rather coriaceous, 
shining. Branches rather tetragonal. h. 6ft.

somewhat resembling a Holly. Japan. A very handsome, 
evergreen shrub, revving considerably in the size and toot 
of the leaves. (G. C. n. s., vi. 689.) 0. ilicifoliusis a form wi 
smaller leaves, and of more dense, com habit; of this, 
there are several variegated forms in ¢ tivation, which may 
be propagated by cuttings, but are more rapidly increased by 
ting on stems of Privet. O. myrtifolius is a fixed sport, of 
ense habit, and with rigid, spineless leaves,
