732 ASCLEPIADEE (Brown). [ Pachycarpus. 
corolla-lobes apparently spreading so as to form a broad cup, about 
6 lin. long, 34-4 lin. broad, ovate, acute, glabrous on both sides, 
apparently whitish or sulphur-yellow, varying according to Schlechter 
to golden-yellow, purple-tinted on the back at the tips ; corona-lobes 
4-41 lin. long, entirely dark purple-brown, with the basal half very 
spreading, oblong, 14-1} lin. broad, bearing a pair of erect deltoid 
keels, contiguous and very fleshy at their base, thinner and rather 
widely gaping above, rising to about half-way up the anthers ; upper 
half of the lobes abruptly inflexed over the basal keels and staminal 
column, with their tips meeting at the centre, slightly constricted just 
above the bend, then dilated into an ovate obtuse blade 14-1} lin. 
broad ; staminal column about 2 lin. long; anther-appendages 
broadly ovate, acute, inflexed over the margin of the somewhat 
crater-like style-apex. Gomphocarpus insignis, Schlechter in Engl.

This is doubtfully distinct from P. transvaalensis, and seems only to differ in its 
more pubescent leaves and the much smaller humps or keels on the base of the 
corona-lobes. I have seen only one gathering of each. 
18. P. decorus (N. E. Br.) ; stem scabrous to nearly glabrous, 
only the upper part seen ; leaves ascending or somewhat spreading, 
very shortly petiolate, 2}-34 in. long, } to nearly 1 in. broad, 
lanceolate, narrowly oblong-lanceolate or linear-oblong, acute or 
subobtuse, cuneate to subtruncate at the base, thinly and rigidly 
scabrous on both sides, scabrous on the margins ; umbels lateral at 
the nodes and terminal, pedunculate, usually 3- (sometimes 4-) 
flowered ; peduncles }—2 in. long, scaberulous on one side ; bracts 
3 in. long, linear or linear-subulate, acute, scabrous-ciliate ; pedicels 
7-1} in. long, scaberulous or scabrous; sepals } in. long, 2-2} lin. 
broad, ovate or lanceolate, acuminate, pubescent ; corolla broadly 
cup-like, lobed nearly to the base, apparently yellow or creamy- 
white ; lobes about 7 lin. long, 4-51 lin. broad, elliptic-ovate or 
oblong-ovate, acute, glabrous on both sides or slightly adpressed 
pubescent at the tips on the back ; corona-lobes apparently entirely 
yellow or white, about 5 lin. long, spreading or ascending-spreading, 
perhaps somewhat incurved at the apex, slightly dilated and 2-2} 
lin, broad at the base, which bears a pair of fleshy contiguous erect 
deltoid very obtuse keels, rising to about 3 of the height of the 
staminal column, faintly constricted just beyond the keels, with the 
terminal part 14-1} lin. broad, varying from oblong-lanceolate to 
subhastate-lanceolate, obtuse ; staminal column 2 lin. long ; anthers 
with a large wedge-shaped blackish-violet spot on the upper part, 
and suborbicular or broadly rounded obtuse appendages inflexed 
over the truncate or slightly depressed style-apex.
