Stapelia. | ASCLEPIADEA (Brown). _ 1013 
spotted with darker ; outer corona-lobes sublinear, bifid or 3-toothed 
at the apex, with straight teeth, the middle one minute ; otherwise 
as in S. variegata. | 
(91. S. rectiflora (Riist in Monatsschr. Kakt. vi. 37); corolla 
about 2 in, in diam., with a shallow cup-like disk and spreading 
lobes, sulphur-yellow, with rounded and not very numerous purple- 
brown spots having a tendency to be confluent in longitudinal 
rows, and slender purple-brown lines between the rugosities ; 
annulus circular, paler, dotted with purple-brown ; outer corona- 
lobes linear-oblong, bifid to about } of the way down, with parallel 
teeth, pale yellow, dotted with purple-brown at the apex only, no 
basal spot ; outer horn of the inner corona-lobes spreading. | 
Var. viridula, Riist, lc. 37, only differs in having the corolla more densely 
spotted and the spots on the disk at the base of the lobes confluent in a continuous 
ring around the annulus. 
(92. S. salmiana (Riist in Monatsschr. Kakt. vi. 39); corolla 
3-31 in. in diam. ; lobes ovate, shortly acuminate, shortly ciliate, 
light yellow, with numerous irregular purple-brown spots, those at 
the base and on the disk around the annulus confluent ; annulus 
circular, of a ‘paler yellow than the lobes, densely covered with 
moderately large purple-brown spots ; outer corona-lobes linear- 
oblong, 3-toothed at the apex, with the middle tooth minute, pale 
yellow, dotted on the teeth with purple-brown, with or without 
2 small spots near the base ; inner corona-lobes only dotted on the 
apical half of their horns ; outer horn spreading. 
This is very similar to S. variegata, var. trisulea, differing chiefly by its ciliate 
corolla-lobes. } 
(93. S. sanguinea (Riist in Monatsschr. Kakt. vi. 38, not of 
Pasq.) ; corolla 2} in. in diam.; lobes minutely or very shortly 
ciliate, blackish-brown or violet-brown, with a few yellowish dots or 
small spots on their basal part and a few pale yellow lines meander- 
ing in various directions on the apical half and usually separating 
one large and two small spots from the rest of the brown colour ; 
annulus circular, yellowish with small round purple-brown spots ; 
outer corona-lobes bifid, pale yellow, with a central stripe and 
some dots on the teeth of purple-brown; inner corona-lobes with 
the outer horn suberect. | 
(94. 8. Sisyphus (Dammann ex Riist in Monatsschr. Kakt. 
vi. 38) is very similar to S. variegata, var, atrata, and is probably a 
hybrid derived from it or of similar origin ; corolla-lobes ovate, 
acuminate, very dark purple-brown or violet-brown with a crescent- 
like marking and a few dots of yellow at their tips, not ciliate ; 
annulus circular, of a much lighter purple-brown with yellow dots _
