BARNADESIA (named after Michael Barnadez, a Spanish botanist). ORD. Compositæ. Pretty greenhouse deciduous shrubs, requiring a dry atmosphere. They should be grown in peat, loam, and sand, in equal proportions. Propagated either by seeds, sown in hotbeds in March, or by cuttings, made of half-ripened wood in April, and placed in sand under a bell glass.

BARNARDIA. Included under Scilla (which see).
BAROMETER. An instrument for measuring the density of the atmosphere, and hence determining the probable changes of weather, or the height of any ascent. To the gardener the Barometer is indispensable as a warning to take due precaution.
BAROSMA (from barys, heavy, and osme, smell; referring to the powerful scent of the leaves). Name often incorrectly spelt Baryosma. SYN. Parapetalifera. ORD. Rutaceæ. Very pretty small, Heath-like, greenhouse evergreen shrubs, from the Cape of Good Hope. Calyx equally five-parted; petals five, oblong; stamens ten. Leaves opposite or scattered, coriaceous, flat, dotted, with their margins sometimes glandularly serrulated, sometimes almost entire or revolute. They thrive in a mixture of sand, peat, and a little turfy loam, with good drainage and firm potting. Cuttings, taken from ripened wood, inserted in a pot of sand, and placed in a shady position in a cool house, with a bell glass over them, will root readily in a few weeks.
B. betulina (Birch-leaved). fl. white, axillary, solitary. February to September. l. opposite, obovate, serrulate, sessile, spreading. h. 1ft. to 3ft. 1790. (B. M. Pl. 45.)
B. dioica (diœcious).* fl. purplish; peduncles axillary, usually in threes, shorter than the leaves. April. l. scattered; upper ones ternate, lanceolate, tapering to both ends, full of glandular dots, spreading. h. 1ft. to 2ft. 1816. (B. R. 502.)
B. latifolia (broad-leaved). fl. white, usually solitary, lateral. July. l. opposite, ovate-oblong, sessile, serrulated, smoothish, without glandular dots; branches villous. h. 1ft. 1789.
B. pulchella (pretty).* fl. pale red or purple; peduncles axillary, usually solitary, exceeding the leaves. February. l. crowded, ovate, quite smooth, with thickened, crenate-glandular margins. h. 1ft. to 3ft. 1787.
