scabrous, with the papille in the throat of the tube not hair-tipped ; outer corona 
entirely blackish-crimson or blackish, with a narrow disk and 5 pairs of obtuse 
teeth scarcely } lin. long; inner corona-lobes 1-1} lin. long, rising nearly to the 
level of the mouth of the tube (in all other forms not nearly attaining to that 
level) ; otherwise as in var. y.

This seems to be a very variable species, since besides the varieties I have 
described, there are others connecting them with one another and the type by 
gradations which it is scarcely possible to indicate clearly by words. It seems to 
merge into H. brevirostris, N. E. Br., through some of its varieties. I am 
informed by Mr, Pillans that all but one of these and probably other forms grow 
together in the same locality, and I believe there can be no reasonable doubt that 
they are hybrid forms resulting from cross-fertilization by insect agency, by 
which alone these plants are fertilized, see Stapelia vuriegata, Linn. 
17. H. humilis (Haw. Syn. Pl. Succ. 30); plant 2-2) in. high, 
compact ; stems erect, 7-10 lin. thick, acutely 4—5-angled, glabrous, 
green, glaucous?; angles with acute spreading deltoid teeth 1-14 
lin. long; flowers solitary according to Masson, but in Bain’s 
specimen 4-5 or more are successively produced on a very short 
peduncle near the base of the young stems; pedicels }—} in. long, 
glabrous; sepals 2}-3 lin. long, lanceolate-subulate, glabrous ; 
corolla in bud much flattened, pentagonal, very shortly abruptly 
and acutely pointed at the centre, with 5 small acute teeth at the 
angles and 5 very prominent ribs radiating from the point, glabrous, 
when expanded 1-1} in. in diam., with a very shallow saucer- 
shaped tube and a very abruptly spreading limb, lobed to more 
than half-way and raised into a broad convex ring around the 
mouth of the tube, glabrous; lobes deltoid in Masson’s figure, 
deltoid-ovate and minutely papillate in Bain’s specimen, very acute, 
pale yellow, dotted with blood-red ; ring smooth, blackish-purple, 
marked with undulated whitish spots; outer corona small, with 
very short transverse bifid lobes or subequally 10-toothed ; inner 
corona-lobes about $ lin. long, ovate, acuminate, incumbent on the 
backs of the anthers and not produced beyond them. Schultes, Syst.

The details of the flowers, except as to colour, are described from Bain’s 
specimen, which agrees so well with Masson’s figure in general characters that I 
believe it to be this species, the colour of its flowers, however, is unknown to me, 
as the specimen was received preserved in alcohol.
