Hab. Malange, in thickets at N'Bango ; Gossweiler, 1215. 
Near D. sessiliflora, Marv., and D. membranacea, S. Moore, but 
easily distinguished by the quite different involueral leaves. 
The description of D. Poggei, O. Hoffm. (Engl. Jahrb. xv. (1893) 
546) suits it in some respects, but the leaves of this are different, 
as also the inflorescence. Moreover, the heads are described as 
4 cm. long and no less than 3:5 em. broad, 7. e. nearly hemi- 
spherical, and the involucral leaves are evidently unlike. 
Mr. Gossweiler notes that the florets are purplish red.

The only specimens of this species known to me are in the 
British Muscum, and were collected by Francis Masson. Of 
these specimens an elaborate description is among the Solander 
MSS., under an unpublished name which, for obvious reasons, 
is not reproduced here. The specimens agree in every respect
