10. T. cactiforme (N. E. Br. in Hook. Ic. Pl. under t. 1905, by 
error cactiformis) ; plant 2—4 in. high, simple or branching at the 
base into 2-5 cylindric or clavate stems 14-2 in. thick, covered 
with crowded slightly prominent obtusely rounded. pointless 
tubercles, glabrous, whitish-green, flowering at the very obtuse 
apex ; pedicels $ lin. long, glabrous ; sepals ? lin. long, ovate, acute, 
glabrous ; corolla } in. or more in diam., glabrous outside and 
within, not ciliate, papillate-rugulose on the inner surface, pale 
yellow spotted with blood-red; tube distinct, shallowly cup- 
shaped ; lobes spreading, about 1} lin. long and as much or more 
in breadth at the base, very broadly ovate or deltoid-ovate, abruptly 
and shortly acuminate; outer corona-lobes ascending-spreading, 
2 lin. long, divided nearly to the base into 2 linear-falcate widely 
diverging segments which form mandible-like pairs of teeth with 
those of the adjacent lobes behind the inner corona-lobes, yellow, 
dotted with blood-red ; inner corona-lobes } lin. long, linear, obtuse, 
closely incumbent upon the backs of the anthers and not produced 
beyond them, dorsally connected at the base to the outer corona 
and there produced into a short suberect tooth ; follicles diverging, 
slightly incurved, 1}-2 in. long, 3-34 lin. thick, terete-fusiform, 
acute, glabrous. K. Schum. in Engl. und Prantl, Pflanzenfam. iv. ii.

Western REGION : Little Namaqualand ; between Koper Berg and Kookfontein, 
Drége, 6399! near Ookiep, ex Pillans, and without precise locality, Barkly, 37! 
Little Bushmanland (Gezelschaps Bank ?), Paterson ! 
Also in Tropical German South-west Africa. This remarkable plant, so far as 
known to me, has only flowered in Europe once, in 1844, when it was figured in 
the Botanical Magazine from a plant sent by Zeyher from Little Namaqualand, 
all the other figures, except Paterson’s, are copied from that one. 
11. T. simile (N. E. Br.); stem not seen, but according to a 
sketch resembling that of T. cactiforme, oblong or globose-obovoid 
and up to 1# in. high and 14 in. thick, “ quite smooth, only a little 
wrinkled ” (Marloth), flowering at the top; pedicels 1} lin. long, 
‘glabrous; sepals 4-3 lin. long and quite as broad, broadly ovate, 
acute, glabrous; corolla 4} lin. in diam., quite glabrous and not 
ciliate on the lobes, smooth outside, minutely papillate-rugulose on 
the inner face of the lobes, “deep purple-brown” (Marloth) ; tube 
1} lin. long, 23 lin. in diam. outside, cup-shaped ; lobes spreading, 
1} lin. long and as much in breadth, triangular in outline, acute ; 
outer corona shortly cupular at the base, acutely 15-toothed, with 
the teeth arranged in 5 groups of 3 behind the inner corona-lobes 
and the lateral teeth longer than and arching over the middle tooth,
