M. africana, Miill. Arg., is a species the characters of which have always been 

 obscure. It was based in the first instance upon specimens collected in Angola by 

 Welwitscli, and issued as n. 401 and 401b. The plant referred to 401b is, however, 

 Spirostachyfi africana, Sond., and not a Maprounea at all; under 401 has been 

 issued a mixture of flowering specimens of Sjnrostachys africana, Sond., with 

 fruiting specimens of the particular Maprounea distinguished by Pax & Hoffmann 

 ■a.s M. africana, var. henguelensis. It is owing' to this circumstance that Miiller has 

 described the spikes of M. africana as lateral, sessile and, when young, cylindric. 

 Those statements, accurate as regards the Spirostachys from which Miiller's descrip- 

 tion was taken, are not applicable to the flowering spikes of M. africana, which 

 are always terminal on specialised branchlets and when young are shorter as com- 

 pared with their diameter than they are at later stages. We have failed to find a 

 good character whereby to distinguish var. obtusa. Pax, from typical M, africana, 

 :and we maintain var. orientalis. Pax & K. Hoffui., on the authority of its authors 

 with a feeling that the communication of fuller material may render its recognition 

 unnecessary. On the other hand, it is not impossible that var. leueosperma. Pax & 

 K. Hoffm., may ultimately prove, as M. gracilis has proved, to deserve separate 

 recognition; while var. cinnamomea, Pax & K. Hoffin., may also, when more fully 

 linown, call for separate treatment.
