The specimen in Herb, Bolus, mentioned by Dr. Schlechter under Gompho- 
carpus parviflorus, without quotation of number or locality, I learn from Dr, 
Bolus is his No. 5704, from near Pretoria. Gerrard 1951 has oblong-lanceo- 
late leaves, rounded at the base, but does not otherwise differ from the more 
cordate-leaved typical form, and is connected with it by Burtt Davy’s 2966 with 
lanceolate, rounded-based leaves. 
16. X. tysonianum (N. E. Br.); stems probably several from a 
tuber, branching at the base only, 6-9 in. long, apparently decumbent, 
more or less pubescent, with short spreading jointed hairs; leaves 
5-8 pairs to a stem or branch, 3-14 in. distant, spreading; petiole 
1-2 lin, long; blade 3-2 in. long, 4-8 lin. broad, ovate-lanceolate 
or oblong-lanceolate, acute at the apex, broadly cuneate, rounded or 
slightly subcordate at the base, flat, thinly pubescent on both sides 
with spreading hairs; umbel solitary, terminal, pedunculate, hemi- 
spherical, 16-20-flowered; peduncle 14-4 in. long, pubescent ; 
bracts 11 lin, long, subulate, pubescent, very deciduous ; pedicels 
3 lin. long, pubescent with short spreading hairs ; sepals 14-1} lin. 
long, about + lin. broad, lanceolate, acute, pubescent ; corolla about 
2 lin. in diam., pubescent outside, glabrous within, yellow or 
greenish-yellow; lobes 11-11 lin. long, 1-11 lin. broad, ovate or 
elliptic-ovate, subacute, erect, incurved at the apex over the corona, 
the sides slightly folded back at the lower half; corona-lobes arising 
about 1 lin. above the base of the staminal column and shortly 
overtopping it, 3-1 lin. long, 1-2 (or when dorsally pressed $) lin. 
broad, erect, not contiguous (unless dorsally pressed), thick and 
fleshy, compressed-oblong (or elliptic from dorsal pressure), obtuse, 
slightly incurved upon the anther-tips at the apex, flat on the inner 
face, very convex on the back ; staminal column 1 lin. long; anthers 
very small, erect, quadrate, their appendages reniform, erect, applied 
to the margin of the style-apex, and their wings small and not very 
conspicuous; style-apex cushion-like, not exceeding the anther- 
appendages ; follicle solitary, erect upon a deflexed pedicel, lanceo- 
late, gradually tapering into a beak, smooth, puberulous. Gompho-
