leaves petiolate, spreading, glabrous; petiole }—-{ in. long; blade 
31-5 in. long, 13-2} in. broad, oblong, with nearly parallel sides, 
very abruptly cuspidate, the point 4-5 lin. long, acute, broadly 
rounded and shortly cordate at the base, with small overlapping 
lobes; midrib very stout, without glands along its upper side ; 
veins numerous, horizontally spreading ; cymes lateral, 5-9-flowered, 
1-11 in. in diam., glabrous in all parts; peduncle 1—} in. long; 
pedicels 2-4 lin. long; sepals 1 lin. long, ovate-lanceolate, acute ; 
corolla rotate, 5-lobed nearly to the base, $ in. in diam., light green ; 
lobes 4—5 lin. long, 13 lin. broad, very spreading, lanceolate, acute, 
somewhat twisted and curved; corona-lobes inserted midway 
between the base of the stamens and the sinuses between the corolla- 
lobes, 4 lin. long, filiform, erect, flexuose ; stamens connivent over 
the style; filaments 3 lin. long, filiform, free, not connected into a 
ring at the base; anthers 1 lin. long, lanceolate, acute, subtruncate 
or slightly emarginate at the base, glabrous; pollen-carriers oblong, 
obtuse, channelled down the middle; apex of the style 5-angled, 
obtusely conical, much shorter than the anthers ; follicles about 
31 in. long, 3 in. thick, widely diverging, fusiform-lanceolate,

Eastern RxEGion: Transkei; near Kentani, 1000 ft., Miss Alice Pegler, 
916! Natal; in a forest near the Umbogintwini River, Umlazi native location, 
Wood, 3634! and without precise locality, Gerrard, 780! 
This plant was raised at Kew from seeds taken from Gerrard’s specimen, and 
flowered in March, 1867. I cannot distinguish Pentopetia by any technical 
characters from Tacazzea. 
VI. CHLOROCODON, Hook. f. 
Calyx 5-partite. Corolla subrotate, 5-lobed nearly to the base; 
lobes overlapping to the left in bud. Corona of 5 lobes arising 
from the base of the staminal filaments, free, very broadly obcordate 
or obreniform, with or without an erect or incurved dorsal process. 
Stamens arising from the base of the corolla ; filaments very short 
and broad; anthers large, triangular, adnate to the dilated part of 
the style, connivent in a cone, connate at the tips. Pollen granular. 
Style shortly conical at the apex, not exceeding the anthers. 
Tall climbers; leaves large, opposite, cordate ; stipules well developed, toothed 
or frill-like ; flowers of moderate size, in paniculate cymes. 
Distris. A genus of two species, both Tropical African, of which only one
