of the ingredients in the manufacture of snuff. Abundant 

 in sandy soil in many parts of the colony, where it flowers 

 from September to November. 



SUTHERLANDIA. R. Bii. 

 {Le^uminoscB.) 



XVII. 6. DIADELPHIA DECANDRIA. LIN. SYST. 



25. Sutherlandia frutescens. R. Br. Shrubby. Stej7i 

 erect, twiggy. Leaves stalked, alternate, impari-pin- 

 nate, many-yoked ; pinnules on short petioles, oblong, 

 obtuse, emarginate, silky. Floicers racemose, pedun- 

 cled, axillary, scarlet. Lecjume ovate, scarious, inflated. 



A fine showy shrub, which, on account of its beautiful 

 scarlet flowers, is a horticultural ornament, and cultivated 

 as such in our gardens. It grows wild in hilly parts all 

 over the colony. According to Thunberg (Travels, vol. I., 

 pag. 160), the roots and leaves of this plant, when dried 

 and pulverised, are of use in diseases of the eye. 



ACACIA. Neck. 



(^Leguminosce.) 



XVI. — 9. MONADELPHIA POLYANDRIA. LIN. SYST. 



26. Acacia horrida. Willd. A large tree. Stem 

 and branches glabrous, but armed with large white 

 spinous stipules. Leaves bipinnate ; pinnm 2-3 yoked ; 

 pinnules many-yoked, oblong, blunt. Leafstalks glan- 

 dulous at base and on the apex. Flowers stalked, 

 axillary, globose, polygamous, yellow, scented. 



The demulcent derived from the Doornboom is well 

 known as an article of commerce. It exudes spontane- 

 ously from the bark of the trunk and branches, and hardens 

 in the sun, without losing its transparency. Although the 

 Cape gum is inferior in appearance, and in intrinsic value, 

 to that of Northern Africa, it may yet be improved by care 

 and attention. The bark of this useful tree is highly 

 astringent, hence its effect, in the form of decoction, in 

 inveterate fluor albus, in diarrhoea, dysentery, and as a 

 substitute for the Peruvian bark in fevers. The Acacia 

 giraffcB. Willd. (Kameeldoorn), growing beyond the limfts 

 of the Cape Colony, is said to yield a superior gum, and 

 is eaten by the natives.
