958 ASCLEPIADEA (Brown). | Stapelia. 
published plate. No pubescence is represented on the stems in the drawing nor 
is it described, so they are probably glabrous as in the closely allied S. divaricata, 
Masson, from which it differs in its more compact erect habit, flatter and less 
acuminate corolla-lobes and the absence of ciliation. 
26. S. Pillansii (N. E. Br. in Gard. Chron. 1904, xxxv. 242, 
fig. 100); stems rather crowded, 4-5} in. (5-7 in., Pillans) high, 
6-10 lin. (7-1 in., Pillans) square, with concave sides and angles 
not much compressed, velvety pubescent, green; teeth not very 
prominent, with erect adpressed rudimentary leaves 1-14 lin. long ; 
flowers 2-5 together near the base of the stems and 2 or more some- 
times open at the same time ; pedicels }—1} in. long, 14—2$ lin. thick, 
velvety ; sepals about 4 lin. long, lanceolate, acute or acuminate, 
velvety ; corolla in bud long-acuminate from a narrowly pentagonal- 
ovoid base, not twisted, when expanded 4—5} in. in diam. with the 
lobes extended, velvety-puberulous on the back, smooth to slightly 
transversely rugose and glabrous on the inner face, purple-brown, 
without markings, shining, densely ciliate with soft light purple 
simple hairs, which are shorter and fewer and become absent 
towards the tips ; disk flattish, depressed at the centre; lobes 13- 
21 lin. long, 7-9 lin. broad, lanceolate, attenuate into tail-like tips, 
variably spreading or recurved, not revolute at the margins ; outer 
corona variable, blackish, shining, either of 10 free ascending lobes 
2} lin. long, 5 of them alternating with the inner corona-lobes, 
flattish, oblong or oblong-obovate, 1-1} lin. broad at the top, which 
is abruptly acuminate or somewhat 3-toothed or abruptly rounded 
into a short central obtuse point, 5 others at the back of and 
adpressed to or united with the inner corona-lobes, about # lin. 
broad, linear or oblong-linear, obtuse, truncate, notched or bifid at 
the apex ; or the 5 lobes alternating with the inner corona-lobes 
narrower and oblong, and alternating with 5 pairs of filiform teeth ; 
or of 5 very deeply 3-fid lobes with filiform lateral segments ; or 
all the lobes connate at the basal part into a cup, divided above 
into 5 regularly 3-toothed or irregularly several-toothed lobes ; 
inner corona-lobes about 3 lin. long, blackish, shining, with the 
dorsal-wing 1} lin. broad, adnate for 1-2 of its length to the 
inner horn, its free part oblong or rounded, very obtuse, entire 
or obscurely crenulate; inner horn recurving, very stoutly 
triquetrous, acute to subobtuse, slightly longer than the dorsal 
wing ; dried follicles subparallel, 6 in. long, puberulous; seeds 
24 lin. long, 14 lin. broad, ovate, with thick incurved margins on 
one side, convex on the other, smooth, glabrous, light brown. 
N. E. Br. in Gard. Chron. 1908, xliv. 187, fig. 79. 
Var. B, attenuata (N. E. Br.); corolla in bud twisted at the apex, when 
expanded 64-8 in. in diam., with the lobes 23-3} in. long, with very long tapering 
points ; otherwise as in the type.
