Hippophae. | LXV, ELDAGNACEZ, 389 
I, HIPPOPHAE. HIPPOPHAE. 
Shrubs or small trees, distinguished as a genus by their dicecious flowers ; 
the males in axillary clusters, with a perianth of 2 small segments and 4: 
stamens; the females solitary, with a tubular perianth, minutely 2-lobed, 
which becomes succulent, forming a berry round the true fruit. The 
reduced perianth and clustered flowers show considerable affinity with 
Myrica. 
1, H. rhamnoides, Linn. (fig. 880). Common Hippophae, Sallow- 
Thorn, Sea Buckthorn.—A willow-like shrub, covered with a scaly scurf, 
very close and silvery on the under side of the leaves, thin or none on the 
upper side, dense and more or less rusty on the young shoots and flowers; 
the axillary shoots often ending in a stout prickle. Leaves alternate, linear, 
and entire. Male flowers very small, in little clusters resembling catkins. 
Females crowded, although solitary in each axil; the perianth about 2 lines 
long, contracted at the top, with the style shortly protruding, forming when 
in fruit a small yellowish or brown berry. 
In stony or sandy places, especially in beds of rivers and torrents, in 
central and eastern Europe and central and Russian Asia, also occasionally 
near the seacoasts of the Baltic and the North Sea. In Britain, very local 
and only near the seacoasts of some of the eastern and southern counties of 
England. Fl. spring. 
LXVI. SANTALACEA. THE SANDALWOOD FAMILY. 
A family limited in Britain to a single species, but compris- 
ing several exotic genera, chiefly tropical or southern, differing 
from Thymeleacee in the perianth combined with the ovary at 
its base, in its valvate, not imbricate, lobes, and in minute but 
important particulars in the structure of the ovary. 
I, THESIUM. THESIUM. 
Low herbs or undershrubs, with alternate entire leaves, no stipules, and 
small flowers. Perianth adhering to the ovary at the base; the limb divided 
into 4: or 5 lobes or segments, valvate in the bud. Stamens 4 or 5, oppo- 
site the lobes of the perianth. Ovary inferior, 1-celled, with 2 ovules sus- 
pended from a central placenta. Style short, with a capitate stigma. | 
Fruit a small green nut, crowned by the lobes of the perianth. Seed 
solitary, with a small, straight embryo in the top of the albumen. 
A considerable genus, widely spread over Europe and temperate Asia, 
but chiefly abundant in southern Africa. Some of the European species 
have been ascertained to be partially parasitical on the roots of other plants, 
to which they attach themselves by means of expanded suckers, like Rhi- 
nanthus and some others of the Scrophularia family. 
1, T.linophyllum, Linn. (fig. 881). Mlaxv-leaved Thesium. Bastard 
Toadflax.—aA glabrous, green perennial, forming a short, woody rootstock, 
with several annual, procumbent or ascending, stiff stems, usually simple, 
6 or 8 inches long, but sometimes near a foot, Leaves narrow-linear, or, 
when very luxuriant, rather broader, and above an inch long. Flowers
