scarlet or white, large, usually rising laterally from the 
trunk or branches, either singly orin clusters. They grow 
best in a rich loamy soil. Cuttings, not too ripe, taken off 
at a joint, placed in sand under a bell glass, in moist heat, 
= will root readily; but plants raised from seeds brought 
from their natural habitats make finer trees.

“hardy tuberous-rooted perennial, requiring a sandy soil, 
and good drainage, with protection at all seasons from

ORD. Scrophulariacee. A small genus of usually glabrous, 
rarely pilose, slender, creeping or erect, annual, biennial, or 
perennial stove plants, almost unknown in cultivation. 
Flowers axillary, opposite, or alternate from abortion, 
usually pedicellate, the upper ones sometimes racemose, 
pinkish, or blue. Leaves opposite, quite entire, or toothed. 
They thrive in a rich sandy loam. ‘The annual species are 
propagated by seeds, the others by divisions and cuttings.

French naturalist, who wrote some botanical papers in 1754).

stove trees or shrubs. Flowers large, terminal; peduncles 
one or many-flowered. Leaves scattered, exstipulate, 
coriaceous, entire, one-nerved, marked with transverse 
veins, sub-sessile, narrowed to the base. They thrive well 
in a mixture of loam and peat. Cuttings of firm young 
shoots will root if placed in sand under a hand glass, in a 
: moderate heat. :

having spirally-coiled inflorescence; corolla usually regular 
and five-lobed, with an imbricated estivation; throat gene-

_ alternate, rough. Among other genera belonging to this 
order may be named Anchusa, Borago, Cynoglossum, 
Echium, Lithospermum, and Myosotis.

ruption of some eastern name). Borage. ORD. Boraginacee.

the young cuttings in a cold frame. They may also be 
raised from seed, which should be sown from March to 
May, in any good garden soil, and the plants, when large 
enough, thinned out to lft. or more apart. In hot 
weather, Borage is generally in demand for claret cup and 
other drinks. e

BORASSUS (a name applied by Linneus to the 
spathe of the Date Palm). ORD. Palmacee, A very small 
genus of stove trees, containing two noble species, which 
are distinguished by unisexual flowers, produced upon dis- 
tinct plants, the males being borne in dense branching 
catkins, and the females on simple, or, more rarely, slightly 
branched spikes. Fruit very large, brown, three-seeded. 
Leaves fan-shaped, with spiny petioles. Trunks unarmed, 
often 70ft. high. They may,be grown in good fibrous loam, 
leaf mould, and sand, mainly the former. Increased by 
seeds only, which require to be sown in strong bottom 
heat. Rarely seen in cultivation.
