This plant may prove a variety of B. senegalensis. B. angustifolia, Ilarv. Fl. Cap. i. 19.' 

 Thes. Cap. t. 134, does not belong to the genns. The specimens from Abyssinia and the 

 Niger have smaller flowers and fewer stamens than the rest. 



3. B. salicifolia, Oliv. A shrub, sometimes arborescent. Branches 

 glabrous or the extremities pubemlous. Leaves elongate, linear linear-oval 

 or -lanceolate, acuminate acute or sometimes obtuse, minutely puberulous or 

 scabrid at first, glabrous at length or still rough to the touch on the upper 

 surface, usually 2-5 in. long, 5-9 lines broad. Petiole 3-6 lines. Flowers 

 racemose, racemes axillary, \-\ the length of the leaves or upon short lateral 

 shoots, glabrous or pubescent Pedicels 1 or 2-6 lines ; bracteoles minute, 

 subulate, early deciduous. Sepals reflexed. Stamens 6-14, inserted within 

 the annular disk. Ovary ovoid or obpyriform, narrowed into a very short 

 style, 1-celled with 2 placentas; gynophore \-\\ lines. Fruit not seen, 

 probably 1-seeded.

Mozanxb. Distr. Shire river. Dr. Kirk ! 



In the specimen from Madi the flowers appear to expand- as soon as or before the leaves, 

 and the pedicels are longer, but I do not find any sufficient ground for specific distinction. 

 Dr. Kirk states that the knotty root is boiled and eaten on the Shire. Can this be the 

 doubtful Capparidea with the habit of a Pine, figured and referred to by Schweinfurth (PI. 

 Nilot. 18. tt. 6 and 14) ? 



4. B. xnicrophylla, Oliv. A glabrous shrub or small tree, often with 

 spinose branches. Branches terete. Leaves small, fasciculate or scattered 

 on the young shoots, coriaceous, oblong-obovate or oblanceolate or nearly 

 linear, obtuse, mucronulate, venation indistinct, 3-8 lines long, on petioles 

 of half a line, more or less. Flowers numerous, in lateral fascicles or um- 

 bellate racemes, equalling or but little exceeding the leaves, nearly glabrous 

 or the pedicels pubescent. Stamens about 4-6, inserted at the base of the 

 gynophore. Ovary globose-ovoid with a short thick style; placentas 2. 

 Stigma obtuse. Fruit not seen.

5. B. urens JFelw. mss. Extremities pubescent. Leaves coriaceous, 

 oblong-elliptical, obtuse, often mucronulate, sometimes rather pointed ; base 

 rounded or cuneate, scabrous or rugose-scabrous above, shortly hirsute- 

 pubescent beneath, in the rugose forms with prominent midrib and lateral 

 veins below, at length 2-4| in. long, ^1| in. broad. Flowers in erect, 

 more or less elongate terminal racemes, often several inches in length ; bracts 

 minute, subulate. Pedicels spreading or ascending, |-^ in. Calyx-lobes 

 ovate, hairy externally with a broad annular disk at base. Stamens 14-20.
