e. Leaves oblique, peltate.

10. B. albo-coccinea. Stems short, inclining to creep. Leaves peltate, oblong, of a dark green colour, covered when young with soft brown hairs which soon drop off, leaving them quite smooth on both sides; but still a soft substance clings to their footstalks, and gives them a rust-like appearance. Flowers in loose panicles of from thirty to forty blooms, elevated on footstalks about a foot and a half in height; petals pure white, contrasting well with the sepals, which are bright scarlet, especially on the outside.—East Indies.

It blooms during the spring months. Brazil.

d. Leaves oblique, ovate, peltate.

18. B. peltifolia grows about three feet in height, stems rather 'woody, and these with the leaves are thickly covered with a white

woolly substance, giving the plant a very hoary appearance. Leaves peltate, about ten inches in length, very thick, and easily broken. Flowers white, in large clusters, suspended by footstalks generally more than a foot in length. Syn. B. pauciflora, B. acida, B. peltata.-Brazil.

20. B. homonyma. Stems from two to three feet in height, enlarged at the joints, and forming a large fleshy base, from which the young shoots spring. Leaves oblique, about three inches in length, inclining to divide into four unequal lobes, smooth on both sides, and generally of a dark green colour. Flowers pure white, generally in threes. This resembles B. parvifolia in habit, but may be at once distinguished from that species by its much larger leaves, which are always of a very dark colour. It blooms during summer and autumn. Syn. B sinuata.-Brazil.

21. B. parvifolia. This species in almost every respect resembles the preceding, except that the stems grow somewhat more erect and are less disposed to branch. The leaves are of the same form and colour, and only differ in being about one-third larger. The flowers individually are similar both in size and colour, suspended in little clusters varying in number from three to five blooms. This, with the former, may be kept in flower during the greater part of the year. Syn. B. floribunda, B. semperflorens.- Cape of Good Hope.
