HuiLLA. — Corollas purple ; achenes obovoid, glabrous (or some- 

 what setulose), without pappus. In elevated sandy pastures between 

 Empalanca and Nene ; fl. and fr. April and May (rainy season) 1860. 

 Seen nowhere else in the district. No. 3998. 



Our specimens vary much in the shape of the leaves, those of No. 

 3997 being oval, ranging up to 2 in. long by 1 in. broad, the upper ones 

 alternate, the rest opposite and often with short young leafy shoots 

 quasi-fasciculate in their axils ; the achenes are 3- or 4-gonous rounded 

 on the back and with several very delicate or obsolete ribs ; they should 

 be compared with G. leiocarpa O. HofEm, in Engl. Pfl. Ost-Afr., C, 

 p. 402 (1895), and are referred as above with some doubt.
