98 NEW AFRICAN ASCLKPIADS, 



Hab. Ambaca. "In dumetis sylvestribus arenosis inter Halo 

 et Zamba," Oct. 1856, Welwitsch, no. 4234. 



According to a rough sketch by Welwitsch, the upper surface ol 

 the tuber has the form of a plate, from the centre of which spring 

 tlie long whip-like shoots ; one of the two preserved is 2i ft. long ; 

 they are dull reddish in colour, and slightly puberulous. The pairs 

 of rather small leaves are separated by long internodes ; they vary 

 in shape from oblong to spathulate ; the largest is 1^ in. long, 

 including the short petiole, by | in. broad ; their dense pubescence 

 gives them a sage-green colour. The calyx-segments are 1 line 

 long ; the corolla-tube 1 line, the lobes a little over 2 lines by 

 1 broad ; the corona- segments situated at the top of the corolla-tube 

 are 2 lines ; the linear filaments are scarcely ^ line long, the anthers 

 1 line ; the pollen-carrier (| line long) has a slender stalk termi- 

 nating in a triangular upper part, the whole shaped like a mattock. 



Is most nearly allied to the South African R. FlanaganL Schltr. 

 and the Tropical African R. vohibilis Schltr., but is easily dis- 

 tinguished by its leaf-characters and shape of the corona-segments, 

 the filiform median tooth of the latter occurring in the two allied 

 species being absent in ours.

Hab. " Sparse in dumetis subsiccis arenosis prope Huilla," 

 Nov. 1859, Welwitsch, no. 4177. 



The description is based on a sketch of a plant and on a small 

 flower -bearing branch, both in the British Museum. The very narrow 

 leaves are 1:^^ in. long, shorter in the floriferous part of the shoot. 

 The pedicels are 2 lines long, the calyx-segments 1 line, the corolla- 

 lobes just over 1 line long and ^ line broad. The corona-segments 

 are ^ line long, including the membranous triangular median tooth 

 which they bear just below the obtuse apex. 



Is very near .S'. masaicum N. E. Br., from Kilimanjaro, but dis- 

 tinguished by the more membranous texture of its flowers, the 

 differently shaped corona-segments and pollinia, the latter being 

 pyriform in the East African species. 



Schizoglossum angolense, sp. nov. Herba parva e tubere 

 subconico et pro ratione niagno nascens ; caule basi lignoso mox 

 herbaceo et ramoso ; ramis patentibus ; foliis linearibus apice 

 pungentibus ; floribus viridescentibus umbellatis, umbellis ramos 

 terminantibus vel axillaribus ; calycis segmentis rotatis anguste 

 lanceolatis acutis ; corolh^ lobis patentibus ovatis vel oblongo- 

 lanceolatis ; coronfe squamis ovatis lobo obtuso super basin ro- 

 tundam utrinque instructis, et facie interne bicarinatis ; filamentls 

 brevissimis, antheras appendice breviter ovata, stigma planum
