concave beneath and sometimes almost pointless, sometimes with a 
short recurving point, sometimes with a slender linear upcurved 
point 2-3 lin. long, with a small tooth on each side near the middle, 
and sometimes the keels are absent and the lobes are small, spread- 
ing, scarcely projecting beyond the anther-wings, ovate or oblong- 
ovate, recurved at the shortly pointed apex, fleshy, with a cut-like 
groove along the upper face and apparently somewhat rib-striate ; 
staminal column 24 lin. long; anther-appendages ovate, acute, 
loosely inflexed over and concealing the style-apex, which sometimes 
(always?) has a central cavity; follicles not seen. P. concolor,

The variability of the corona-lobes of this plant would seem to indicate that it 
may be a hybrid between P. reflectens and one or more other allied species. It is 
closely related to P. validus, but is not so tall, and has much smaller flowers and 
narrower leaves. ‘ 
7. P. validus (N. E. Br. in Dyer, Fl. Trop. Afr. iv. i. 377); 
stem 24-34 ft. high, stout, simple, finely scabrous, leafy to the base ; 
leaves numerous, spreading ; petiole 1} in. long ; blade 25-4} in. 
long, 1-24 in. broad, oblong, very obtuse or subtruncately rounded 
at the apex, apiculate, rounded in and cuneately tapering into the 
petiole at the base, scabrous on both sides and on the margins ; 
umbels lateral at the nodes, sessile or the lower pedunculate, usually 
4-flowered ; peduncles 0-3 in. long ; pedicels 1-1} in. long, finely 
scabrous ; sepals about 7 lin. long, 3} lin. broad, ovate, acuminate, 
finely scabrous; corolla-lobes sometimes reflexed and obliquely 
revolute or twisted, sometimes apparently spreading at the basal 
part then shortly upcurved, with the apical half closely and 
obliquely revolute, forming a somewhat bolster-like rim toa shallow cup, 
when unrolled 9-11 lin. long and 5-6 lin. broad, ovate or lanceolate, 
acute or obtusely pointed, subglabrous or inconspicuously scaberulous 
on the back, rugulose with a very minute velvet-like surface on the 
inner face, but glabrous to the eye, apparently greenish-white, 
sometimes tinted, with purple; corona-lobes consisting of 2 con- 
tiguous erect wing-like (probably fleshy) keels on the upper face of 
a lanceolate acute lobe 24 lin. long, 1} lin. broad, spreading from 
the base of the staminal column and recurved at the apex ; keels 
about } in. long, 14-2 lin. high, with the outer margins curving 
from the apex of the straight vertical puberulous margins next the 
anthers outwards and downwards to the recurved point, probably 
white ; staminal column }~} in. long; anther-appendages ovate, 
subobtuse, half-inflexed over the margin of the flat pentagonal 
style-apex. Gomphocarpus validus, Schlechter in Engl. Jahrb. xviii.
