30 ix. capparidacejs. [Mcerua 



The following perhaps belongs here, at least if M. senegalensis 

 Br. is correctly united with M. angolensis D.O. ; it is the Mcerua 

 ■of Welwitsch referred to by Oliver, I.e., p. 87, under M. Currori 

 Hook. f. :—

Var. buxifolia (Welw.) M. rigida Br., var. buxifolia Oliv., I.e. 

 Mossamedes. — A slender shrub, 3 to 4 ft. high, with whitish flowers.

The following four numbers, the first two specimens with not 

 quite glabrous fruits, appear to belong to this species : — 



Mossamedes. — A bush, 15 ft. high or smaller, with glaucous rather 

 fleshy leaves ; on the sandy heath of Cacimba, near the river Maiombo, 

 fr. June 1860. Coll. Caep. 208. A bush of 10 to 12 ft., in Serra de 

 Cacimba, near Maiombo, rather scarce ; fr. Oct. 1859. Coll. Carp. 945.

 the red-sandy banks at the mouth of the river Bero, without flowers 

 or fruit July 1859. No. 979. A shrub, 3 to 4 ft. high, much 

 branched in various directions, somewhat spinous, with the habit of a 

 Lycium and rather fleshy glaucous foliage ; same locality and date.

The following is very doubtfully placed here : — 

 Benguella. — A glabrous rather glaucous not spinous shrub, as tall 

 as a man ; branches virgate, with the habit of Rosmarinus, terete,
