To those described on p. 478, Vol. I., the following should now be added: D. crinita (hairy). fl. white; racemes very numerous, pendulous, solitary or several in the axils, 2in. to 3 1/2in. long, forming a panicle at the ends of the branches. September. l. long-petiolate; leaflets five, 2in. to 3in. long, petiolulate, elliptic-lanceolate or oblanceolate, obtuse, acute or acuminate, with a long, bristly mucro. Natal, 1884.
