BAUHINIA (in honour of John and Caspar Bauhin, two famous botanists of the sixteenth century). Mountain Ebony. ORD. Leguminosæ. Very showy stove evergreen shrubs. Flowers racemose; petals five, spreading, oblong, rather unequal, upper one usually distant from the rest. Leaves two-lobed, constantly composed of two jointed leaflets at the top of the petiole, sometimes nearly free, but usually joined together, more or less, and with an awn in the recess. They succeed well in a mixture of sand, loam, and peat, requiring good drainage and moderately firm potting. Propagated by cuttings, which should be taken when the wood is neither very ripe nor very young; the leaves must be dressed off, and the cuttings planted in sand, under a glass, in moist heat. Although glorious objects in the tropics, few of the species flower under our comparatively sunless skies; those which hitherto have succeeded well in Britain are marked with an asterisk.

India, 1790. Shrubby climber. (B. F. S. 182.)
B. tomentosa (tomentose). fl., petals pale yellow, with a red spot at the claw, obovate, obtuse; peduncles one to three-flowered. l. ovate or roundish at the base; under surface villous, as well as the petioles, branches, stipules, peduncles, bracts, and calyces; leaflets connected beyond the middle, oval, obtuse, three to four-nerved. h. 6ft. to 12ft.

BEAN BEETLE (Bruchus granarius). This insect, by depositing its eggs in the seeds of Beans and Peas, causes a great amount of injury. It is about an eighth of an inch long, black, with brown hairs and white spots; tip of the tail prolonged, downy; front pair of legs reddish. The most effectual means of prevention is to destroy, when sowing, all seeds infested by it; and this may be detected by the skin of the seed being unusually transparent above the tunnel for exit. Imported seeds of Broad Beans are often much infested. "Dipping the Beans or Peas in boiling water for one minute is stated to kill the grub inside; but, as dipping for four minutes generally destroys the germinating power, the experiment is much too hazardous for general use", (Ormerod).
