-30 IX. CAPPARiDACEyE. [Mceruci 



The foUowiiig perhaps belongs hei^e, at least if M. senegalensis 

 Br. is correctly united with 31. angolensis D.C. ; it is the Mcerua 

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

 Hook. f. :— 



Benguella. — A shrub of a man's height : stems erect, much and 

 patently branched ; leaves glaucous, rather fleshy ; fruit cylindrical, 

 multiform, torulose ; outer covering of the seeds brilliantly scarlet. 

 Not uncommon in sandy thickets between the city of Benguella and 

 the river Catumbella ; in very advanced fruit June 1859. No. 977.

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

 In rough, sparingly bushy, mountainous situations, at the banks of 

 "the river Maiombo, near Cazimba ; fl. and fr. Oct. 1859. No. 975.

 SAMEDEs. — A divaricately branched, rigid, fragile shrub, 3 to 5 ft. high; 

 flowers white-greenish. In dry, rough, mountainous situations near 

 Cazimba, along the road leading to Pomangala ; fl. Oct. 1859. No. 976. 



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. Carp. 208. A bush of 10 to 12 ft., in Serra de 

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

 A shrub, 5 to 8 ft. high, with many stems and densely branched ; on 

 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 

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

 No. 6023. 



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, 

 leafy ; leaves crowded in little clusters on slight elevations on the 

 branches, narrowly linear-spathulate, shortly petiolate, apiculate or
