Masson’s figure of this plant is very badly coloured, as he represents the ground- 
colour of the corolla-lobes as purple-brown marked with irregular yellow lines and 
describes them as ‘‘ purple, with transverse yellow rugosities ;”’ this is really the 
case, but at the same time the effect produced is that the ground colour is yellow, 
spotted and lined with purple-brown. 
[S. mixta and var. pentagona, Riist in Monatsschr. Kakt. vi. 39, seem to be 
hybrid forms of var. bufonia, with a large annulus, but smaller flowers than in 
typical var. mixta ; the lobes are coloured as in the lighter forms of var. bufonia 
and the annulus is of a pale sulphur colour thinly dotted with purple: brown on the 
rim and densely in the cup, very distinctly pentagonal in var. pentagona ; outer 
‘ corona-lobes entire to bifid, with short parallel or diverging teeth, pale yellow, 
dotted with purple-brown on the apical part and down the centre, with (or 
in var. pentagona without) a basal spot ; outer horn of the inner corona-lobes. 
ascending. ] 
Var. g, horizontalis (N. E. Br.) ; corolla dull greenish-yellow on the lobes, with 
numerous closely placed transverse lines (but no spots) on the basal half, numerous. 
dots or very small spots and often a central line on the apical part and a series of small 
contiguous spots around the margin, all dark purple-brown ; annulus pentagonal 
with a rather broad flattish-convex rim, finely granulate-rugose, paler than the 
lobes, with numerous small round purple-brown spots and some slender lines 
between the rugosities ; disk flat or very slightly saucer-shaped under the annulus ; 
lobes not ciliate ; outer corona-lobes linear oblong, bifid to 4 of their length, with 
parallel or more rarely diverging teeth; outer horn of the inner corona-lobes 
straight, horizontally spreading, as long as or slightly longer than the inner horn, 
both clavate at the apex ; otherwise as in the type. S. horizontalis, N. E. Br. in 
Hook. Ic. Pl. t. 1907. 
Sourn Arrica: cultivated in Cape Town Botanic Garden, origin unknown, 
Barkly, 4! and cultivated specimens ! 
When alive this is readily distinguished from all other forms of S. variegata 
known to me by the very distinct coloration, flat-looking annulus and the rather 
finely rugose surface. Its native locality is unknown, but the Bruintjes Hoogte 
plant distributed by MacOwan and Bolus as S. horizontalis may be correctly named ; 
I have not seen living specimens of it. This variety was never common in 
English gardens and seems to have disappeared from cultivation here and in South 
Africa, I have not seen it for over 20 years. 
Var. h, rugosa (N. E. Br.); corolla greenish-yellow with numerous small 
scattered spots and transverse irregular lines of dark purple-brown on the lobes. 
and paler yellow dotted with dark purple-brown on the annulus ; disk flat on the 
back ; annulus with a rather broad flattish rim, pentagonal, with 5 slight grooves 
radiating from the centre to a slight notch at each angle; outer corona-lobes 
linear-oblong, subequally and acutely 3-toothed at the apex ; otherwise as in the 
type. S. rugosa, J. Donn, Hort. Cantab, ed. 3, 43; Jacq. Stap. t. 41; Willd.
