only exception being the midrib, which is tomentose ; while a similar 

 one, from the Letaba River, S.E. Africa, Nelson, n. y]% is noted as 

 " fruit similar to damson plum, colour very dark blue-black, agreeable 

 flavour ; fruits abundantly ; Num-Num of the natives, 20 feet high." 

 I am therefore inclined to think C. tomentosa is only an extreme form 

 of C. edulis, Vahl. In any case this tomentose plant occurs from 

 Abyssinia to Matabele Land. A specimen from Djur, collected by 

 Schweinfurth, is marked "baccis rubris ;" tending to show that it is 

 a rather variable plant. " Carissa, near C. tomentosa, A. Rich," of 

 former edition.

purascens, E. Mey. 



Matabele Land. 



This is enumerated as " Chironia, sp." in the former edition of this 

 work. 



Order BORAGINACE^. 



35. Trichodesma physaloides, A. de Cand. 

 Matabele Land. 



Order CONVOLVULACE.E. 



36. Ipomcea, sp. 



Matabele Land. 



A specimen, with slender villose branches, villose, cordate, acute 

 leaves, f inch long, and small flowers of about the same size, is appar- 

 ently very closely allied to a South African species at present unde- 

 scribed, but I am not sure of its absolute identity. This is said to 

 have pale yellow flowers, and to it belong the following specimens : — 

 Wood, n. 413 and n. 1424, from Natal, Nelson, n. 253, from Yster 

 Spruit, Burke, n. 118, from the Magaliesberg, and Zeyher, n. 1217, 

 without precise locality. Omitted in former edition. 



37. Ipomcea, sp. 



Matabele Land. 



A specimen, with glabrous twining stems, and funnel-shaped, ap- 

 parently white flowers, 2§ inches long, with glabrous calyx, I am quite 

 unable to identify, and suspect it may prove new. Leaves were not 

 collected. Omitted in former edition. 



38. Ipomcea, sp. 



Matabele Land. 



A specimen, apparently from a small erect shrub, has the young 

 branches pubescent, leaves narrowly oblong, with very oblique, 

 slightly hairy nerves, flowers apparently solitary in the axils, calyx
