where on Drege's label the letter (b) has been read as (e) and the 

 locality u Gekau and Basche " has accordingly been placed on the 

 label instead of " WonderheuveL" 



The specimen from ^Gekaa-Basche " (No, 4920) at Liibeck 

 agrees with the Berlin specimen from Wonderheuvel. 



The Drege plants distributed under the name S. pentandra, 

 E. Mey., are arranged as follows in the Flora Gapensis : 



S. pentandra, E. Mey. ; " Ad fontes Nieuweveld " (a) ; 

 Wonderheuvel " (b) ; " Garip " (c) ; and, " inter Gekau et 



Basche "(e).

It is of interest to notice that the floral structure of Sebaea 

 primulina, A. W. Hill, from Kuruman, agrees very closely with 

 that of S. pentandra, the chief difference being that the filaments 

 of the anthers are inserted in the corolla-tube (section Belmontia) 

 and not in the sinuses. In a few other cases there are equally 

 striking cases of parallel species in the sections Eusebaea and 

 Belmontia to which attention will be drawn.

This species bears a certain resemblance to specimens of 

 o. pentandra, E. Mey., especially those collected near KimDeriey 

 by Flanagan, in the calyx-wings and in the anthers with their 

 toree glands. The position of the filaments, and the radical leal- 

 rosette, afford characters for separating this species from 

 «• pentandra.

Some confusion has occurred between this species and f"™** 

 Gilg, from which it differs in its relatively long wtemodes^owto- 

 lanceolate leaves and smaller and more compact inflorescences.
