BULLACE, or MUSCADINE. See Vitis vulpina.
BULLATE. Blistered or puckered.
BULRUSH, or CLUB-RUSH. See Typha.
BUNCHOSIA (from bunchos, the Arabic name for Coffee; in allusion to the similarity between the seeds of this genus and those of Coffee). ORD. Malpighiaceæ. Ornamental greenhouse evergreen shrubs, nearly allied to Malpighia, but having the racemes of flowers axillary. Fruit fleshy, indehiscent, externally smooth, and containing two or three seeds. They thrive best in a compost of loam, peat, leaf soil, and sand, in about equal proportions. Cuttings of ripened shoots will root in sand under a bell glass, in moist bottom heat, taking several weeks to do so. Good drainage is essential, both in striking cuttings and in the cultivation of the plants.
FIG. 302. BURBIDGEA NITIDA.
B. argentea (silvery).* fl. yellow; racemes opposite, simple, pubescent. July. l. lanceolate, silvery beneath. Branches puberulous. h. 10ft. Caraccas, 1810.
B. glandulifera (gland-bearing). fl. yellow; racemes simple, axillary. March to May. l. elliptical-ovate, on short petioles, wavy, pubescent on both surfaces, furnished with four glands beneath at the base. h. 10ft. Caraccas, 1806.
B. nitida (shining). fl. yellow; racemes elongated, almost the length of the leaves. July. fr. large, red; it is much eaten by turkeys and other large fowl. l. 4in. long, oblong, acuminated, smooth, glandless. h. 4ft. Jamaica, 1800.
B. odorata (fragrant).* fl. yellow, sweet-scented; racemes opposite. May. l. ovate, emarginate, downy on both surfaces. h. 7ft. Carthagena, 1806.
BUPHTHALMUM (from bous, an ox, and ophthalmos, the eye; the disk of the flower being ox-eye-like). Oxeye. ORD. Compositæ. Very showy and ornamental hardy perennial plants, thriving freely in common garden soil. They are propagated by divisions, made in autumn or spring.
B. grandiflorum (large-flowered).* fl.-heads yellow, large; involucre naked. June to October. l. alternate-lanceolate, somewhat toothleted, smooth. h. 1½ft. Austria, 1722. Hardy herbaceous perennial.
B. salicifolium (Willow-leaved).* fl.-heads yellow, solitary, rather large, terminal; involucre naked. June. l. alternate, oblong-lanceolate, sub-serrated, three-nerved, villous. h. 1½ft. Austria, 1759. Hardy herbaceous perennial.
B. speciosissimum (showiest).* fl.-heads yellow. July. h. 2ft. South Europe, 1826. Hardy herbaceous perennial. SYN. Telekia speciosissima.
BUPLEURUM (derivation not satisfactorily explained). Hare's-Ear. ORD. Umbelliferæ. A somewhat extensive genus of quite glabrous shrubs or herbaceous plants. Flowers yellowish; umbels compound. Leaves mostly quite entire. But few of this genus are worth growing, and all are of the easiest culture in common garden soil. Seeds of the annuals may be sown out of doors in March or April; divisions of the herbaceous perennials made in autumn or spring; and cutting or divisions of the greenhouse species, in March or April.
