or ovate-lanceolate, acuminate, glabrous ; corolla 5-6 lin. in diam., 
rotate, without a distinct tube, glabrous and smooth outside, finely 
to very minutely puberulous all over the inner surface, entirely dark 
purple-brown, or with the part round the corona yellow or orange 
nearly up to the sinuses (Marloth); united part flattish or saucer- 
shaped ; lobes spreading or ascending-spreading, with recurved tips, 
13-2 lin. long, 14-2 lin. broad at the base, deltoid-ovate, acuminate, 
outer corona arising near the base of the staminal column and attain- 
ing to about the same level, forming 5 very short entire or notched 
pouches alternating with the anthers and rising into 5 erect sub- 
quadrate or subquadrate-ovate lobes behind the inner corona-lobes, 
obtusely 3-toothed at the top, with the middle tooth inflexed upon 
and adnate to the base of the inner corona-lobes, which are }—} lin. 
long, linear-oblong, obtuse, incumbent upon the backs of the 
anthers and about half as long as them. Schlechter in Journ. Bot.

I originally described this plant from some transverse slices of the stem with 
flowers attached, which, dried and threaded on a string, were imported into 
America from Bechuanaland as a remedy for piles, and were presented to the Kew 
Herbarium by Mr. E. M. Holmes, of the Pharmaceutical Society, in 1889. Of the 
plavt from the Asbestos Mountains, fresh flowers preserved in formalin were sent 
to Kew by Dr. Marloth, who informs me that the outer corona is of an orange 
colour, and the corona of the type appears to have been of a similar colour, and 
like that of Dr. Marloth’s specimen is glabrous, whilst the Prieska specimen (also 
received in formalin) has the outer corona minutely puberulous on the back, 
and according to a coloured drawing of it is purplish. 
9. T. Marlothii (N. E. Br.); plant 3-4 in. high, with 3-4 
cylindric or cylindric-ovoid branches 14-1} in. thick, narrowed 
below, obtuse, covered with crowded obtuse tubercles 2-3 lin. in 
diam., tipped with a minute point seated in a small depression, 
glabrous, pale greyish ; flowers 2-5 together between the tubercles, — 
subsessile or with pedicels up to } lin. long, developing successively ; 
sepals 4 lin long, }~2 lin. broad, broadly ovate, acute, glabrous ; 
corolla flat-topped and very shortly pointed in bud, when expanded 
about 4 lin. in diam., lobed to half-way down, without a distinct 
tube, the united part flattish or saucer-shaped, glabrous and smooth 
outside and within, not ciliate ; lobes spreading, 1} lin. long and 
broad, nearly like an equilateral triangle in outline, acute, dark 
purple-brown (Marloth); outer corona divided into 10 filiform- 
subulate teeth } lin. long, arranged in pairs behind the inner 
corona-lobes, very spreading, curving towards each other ; inner 
corona-lobes } lin. long, linear, obtuse, closely incumbent on the 
backs of the anthers and produced beyond them, with the tips 
probably connivent-erect. _ es
