320 XLVI1. § CHSALPINIEZ (OLIVER). [ Burkea. 
Confined to Africa. 
The cartilaginous layer described in ‘“ Genera Plantarum,” l.c. as belonging to the 
testa, I regard as albumen. 
1. B. africana, Hook. Ic. Plant. vi. 593-4. Shrub or small tree 
attaining 80 or 35 ft.; extremities stout, ferruginous-pubescent at first. 
Leaves collected towards the ends of the branches, at length ?—1 or 
sometimes 2 or 3ft. long; rachis smooth, glabrous, or clothed with 
deciduous, ferruginous tomentum; pinne usually in about 3 pairs 
(5-6 in var. angolense); leaflets very variable in size, when fully 
developed from 1 to (exceptionally) 3 or 4 in. in length, broadly ovate 
or elliptic-ovate, varying in some forms to elliptical or: oblong, very 
obtuse, entire or minutely emarginate, on first unfolding thinly sil- 
very with appressed hairs, early glabrous, and at length sometimes 
subglaucous, thinly coriaceous, reticulation not prominent. Spikes 
sparingly tomentose pubescent or glabrous, simple or panicled, $—1 ft. 
long. Flowers “‘ white, fragrant,’ numerous, about }in. in diameter. 
Bracts minute, squamiform. Legume 14—24in. long, narrowed at the 
base into a stipes of }—} in. 
Upper Guinea. Nupe Niger, Barter! 
Lower Guinea. Huilla, Angola, Dr. Welwitsch! Var. andongensis. Pinne in 
5-6 pairs; leaflets elliptic-oblong, 9-13 to each pinna. Golungo Alto, Angola, Dr. 
Welwitsch! 
This may prove a distinct species. The specimens are past flowering. The legumes 
agree with the type. Dr. Welwitsch collected fruiting specimens of another variety in 
Huilla (var. cordata, Welw.), distinguished by its more or less distinctly cordate-based 
subsessile or very shortly petiolulate leaflets. 
33. ERYTHROPHL@O0M, Afzelius; Benth. et Hook. f. 
Gen. Plant. i. 588. 
Flowers small, regular. Calyx campanulate 5-fid, lobes ovate or 
lanceolate. Petals 5, oblanceolate, imbricate, pilose externally, but 
slightly exceeding the calyx. Stamens 10, free, filaments filiform gla- 
brous ; anthers small, broadly elliptical or rotundate, dorsifixed. Ovary 
stipitate, pilose-tomentose, 5—8-ovulate; style short or obtuse, terminal 
stigma at first subsessile, style at length accrescent. Legume oblong, 
follicular (by the dorsal suture) or 2-valved in dehiscence; valves 
thickly coriaceous, smooth or but faintly transversely ridged externally. 
Seeds usually 5-8, transverse, compressed, albuminous; cotyledons 
flat, elliptical, with an emarginate base embracing the lower half of 
the short thick radicle-——Unarmed trees. Leaves bipinnate; leaflets 
alternate petiolulate. Flowers very shortly pedicellate in dense 
spiciform, paniculate racemes, collected at the extremities of the 
branches. Bracts minute or obsolete; bracteoles 0. 
Besides the following, confined to W. Africa, there is a Tropical Australian species. 
1, E. guineense, Don, Gard. Dict. ii. 424. A large tree from 40 
to about 100 ft. in height; extremities at first finely rusty-puberulous, 
early glabrous. Pinne in 2-4 nearly opposite pairs 4 ft. more or less
