solid, with an erect obtuse (not recurving) margin, crenately 5-lobed, pale 
yellowish, with purple-brown dots and minute irregular lines ; outer corona-lobes 
oblong-linear, bifid, pale yellow with a purple-brown spot at the base and dots 
down the centre and on the teeth ; inner corona-lobes with the outer horn about 
half as long as the inner horn. 
Var. Thi (Dammann ex Riist, l.c. 37), only differs in having larger and much 
fewer spots on the lobes, and a spot at the base of the outer corona-lobes. 
8. radiata (Riist, l.c. 38, not of Sims), is another form similar to S..angulosa, 
var, Zhi, with large spots on the corolla-lobes, and the outer corona-lobes 
narrowed at the apex and less deeply bifid, without a basal spot.] 
(76. 8. Burtinii (Riist in Monatsschr. Kakt. vi. 40) ; stems rather 
stout ; corolla 24 in, in diam. ; lobes ovate, acuminate, not ciliate, 
pale yellow with very numerous crowded small rounded purple- 
brown spots ; annulus somewhat 5-lobed, with the lobes or angles 
alternating with the corolla-lobes, pale sulphur-yellow or whitish- 
yellow, with a few small scattered purple-brown spots; outer 
corona-lobes oblong-linear, bifid at the apex, pale yellow, dotted at 
the apex and down the centre with purple-brown, no basal spot ; 
inner corona-lobes with the outer horns nearly as long as the inner, 
suberect. } 
[77. 8. chlorotica (Riist in Monatsschr. Kakt. vi. 43); stems 
rather stout ; corolla 13 in. in diam.; lobes deltoid-ovate, acute, 
not ciliate, sulphur-yellow, with small light purple spots and dots, 
those on the disk and base of the lobes larger and more crowded 
than the rest ; annulus circular, paler than the lobes, with irregular 
‘reddish or pale purplish lines and dots mostly radiating from the 
centre to the margin; outer corona-lobes oblong, bifid, with 
slightly diverging teeth, pale yellowish, with 2 small streaks of 
minute purple dots down the centre, without a basal spot; inner 
corona-lobes pale yellow, unspotted, with the outer horn much 
shorter and stouter than the inner. | 
[78. 8. decora (Riist in Monatsschr. Kakt. vi. 40, not of Masson) ; 
this is a hybrid, totally different from S. decora, Masson ; corolla 
2} in. in diam. ; lobes deltoid-ovate, acute, not ciliate, light yellow, 
with the disk around the annulus and 5 broad bands radiating to 
the sinuses of a reddish-brown, the whole spotted with dark purple- 
brown, with the spots on the centre of the basal part of the lobes 
irregularly transversely elongated and larger than the others, many 
of which are dot-like; annulus rather small, 3 in. in diam., 
apparently without a recurved margin, 10-crenate, pale yellow, 
dotted with purple-brown ; outer corona-lobes linear-oblong, bifid at 
the apex, pale yellow, dotted on the teeth and down the centre with 
purple-brown, no basal spot ; inner corona-lobes with the outer horn
