11 R. FILIFOLIA (Thunb. 1 c.) leaves linear-lanceolate, alter- 

 nate ; flowers axillary, i? . G. Native of the Cape of Good Hope. 

 Rafnia, no. 228. Burch. cat. is perhaps referable to this species, 

 of which the branches are roundish, and the leaves linear, also 

 having axillary floriferous branchlets, bearing 2-3 leaves, and 

 1 flower each ; legume pedicellate, inflexed, pendulous. 



Thread-leaved Rafnia. Shrub 1 to 3 feet. 



12 R. RETROFLE'XA (Thunb. 1. c.) leaves obovate ; branches 

 reflexed and rctroflexed. T? . G. Native of the Cape of Good 

 Hope. Stem much branched. Branches flexuous. Leaves op- 

 posite, sessile, obtuse. Flowers axillary, on very short pedicels. 

 There is a specimen in the Linnaean Herbarium from Thunberg, 

 which answers to the above name and character, but the leaves 

 are rather more linear-lanceolate than obovate, and their colour 

 is somewhat glaucous, and the flowers mostly terminal. 



Jletrt>/lexei/-branched Rafnia. Shrub 1 to 3 feet. 



13 R. ERE'CTA (Thunb. 1. c.) leaves oblong ; flowers lateral; 

 stem erect. Tj . G. Native of the Cape of Good Hope. Stem 

 branched, terete. Leaves ovate. Flowers axillary, pedicellate. 



Erect Rafnia. Shrub 2 to 3 feet. 



14 R. DiFFtfsA (Thunb. 1. c.) leaves ovate; stems decum- 

 bent. Tj . G. Native of the Cape of Good Hope, Root fusi- 

 form. Branches diffuse. Leaves alternate. Flowers axillary. 

 Legume pedicellate, crowned by a recurved style. 



Diffuse Rafnia. Shrub procumbent. 



Cult. The species are all worth cultivating, as they are 

 rather elegant when in flower ; their culture and propagation is 

 the same as that recommended for the species of Borbonia. See 

 p. 131.

LIN. SYST. Monadelphia, Decandria. Calyx semi-5-cleft, 

 with the lobes nearly equal, broadest at the base, and rather 

 acute at the apex, but not spinose. Corolla smooth, with an 

 obtuse keel, and a roundish vexillum. Stamens monadelphous, 

 with the sheath cleft in front. Legume compressed, sessile, 

 many-seeded. Smooth Cape subshrubs, with simple, sessile, 

 stem-clasping leaves, which are cordate at the base, the cauline 

 ones alternate, and the floral ones opposite. The flowers dis- 

 posed in fascicles in the upper axils of the leaves, and some- 

 what corymbose, on short pedicels, all yellow, and without any 

 bracteas.

 very obtuse, floral ones coloured. Pj . G. Native of the Cape

 prod. f. cap. 122. Crotalaria amplexicaulis, Lam. diet. 2. p. 194. 

 This species differs from the preceding in the leaves being one 

 half smaller, more rigid, distinctly reticulated, and mucronate at 

 the apex. 



Perfoliate-leaved Vascoa. Fl. July, Aug. Clt. 1812. Shrub 

 2 to 8 feet. 



Cult. For culture and propagation see Borbonia. The plants 

 are rather elegant when in flower.
