912 ASCLEPIADES (Brown). [ Huernia. 
truncate at the apex, black, with a velvet-like surface; inner 
corona-lobes 1-14 lin. long, connivent-erect with diverging tips, 
much exceeding the anthers, linear-subulate, thickened and knob- 
like at the minutely scabrous apex, with a transverse ridge at 
the base, dull purplish-red, brownish at the tips. Schlechter in

I have not seen an authentic specimen of this species and describe entirely from 
a living plant sent to Kew by Mr. Burtt Davy, which quite accords with 
Schlechter’s description except as to the few characters inserted in brackets, and 
comes from the same general locality. In a note, however, Dr. Schlechter states 
that the corolla-tube of this species is longer than that of any other known to him 
and somewhat resembles that of a Decabelone (Tavaresia), although he describes 
the entire corolla as being only ‘‘about 1°5 cm, long,” i.e. about 2 in.

1-3 in. thick, excluding the teeth, sharply 4-5-angled, glabrous, 
light green, sometimes tinted with purple, scarcely glaucous ; flowers 
1-3 together at the lower part of the young stems, opening succes: 
sively ; pedicels }-} in. long, } lin. thick, glabrous ; sepals about 
1 in. long, subulate from an ovate base, glabrous ; corolla campanu- 
late, prominently 20-nerved on the glabrous smooth outside, inside 
(except at the base) covered with short stiff conical processes, 
decreasing in size towards the tips of the lobes, creamy yellow, 
spotted with purple, the spots becoming very crowded and darker 
purple at the middle part of the tube (Pillans), basal part smooth 
and whitish, with transverse dark purple (or blood-red?) lines, the 
processes tipped with dark purple; tube 3-7 in. long, } in. in 
diam. at the mouth; lobes about 5 lin. long and broad, erectly 
spreading in a continuous line with the tube, deltoid, very acute, 
the alternating teeth at the sinuses very prominent ; outer corona 
5-lobed, blackish-purple ; lobes about ? lin. long, ovate, obtuse at 
the shortly bifid apex ; inner corona-lobes 1} lin. long, subterete, 
erect, connivent at the middle, with recurving slightly clavate obtuse 
tips, apparently blackish-purple or dark purple-brown.
