Bo-ey pees, 6 One ce a e286 ee 
Petiole with or without sessile glands. Leaflets 8-11 
pairs, lower 4 in., upper much smaller, strongly-nerved, 
faleate. Stipules narrow, obliquely ovate-lanceolate 26. C. falcinella. 
1. C. Sieberiana, DC. Prod. ii. 489. A small tree, glabrous or the 
extremities and rachis of the leaves and inflorescence puberulous. 
Leatlets in 6—14 pairs, varying with fewer and probably more, ovate- 
elliptical oblong or occasionally ovate-rotundate, obtuse entire or emar- 
ginate or broadly pointed and acute, base rounded or broadly cuneate, 
venulose-reticulate and shining above, paler and sometimes thinly 
puberulous beneath, at least on the midrib, 14-8} in. long, 1-2 in. 
broad ; petiolule 2 lines; common petiole without glands, finely pubes- 
cent or nearly glabrous, 5-12 in. long in our specimens. -Racemes 
from 4 or 5-18 in. long. Bracts usually present during flowering, 
linear or linear-lanceolate, from }—2 in. long; bracteoles subulate, much 
shorter. Pedicels patent or the lower deflexed, 1} in. to nearly 2 in. 
long. Sepals obtuse, 3-4 lines long. Petals broadly elliptical or 
ovate-elliptical, obtuse, unguiculate, 3-1 in. long. Filaments of three 
longer stamens exceeding the petals, filiform or slightly thicker above 
than at the base; the other stamens shorter than the petals. Ovary 
puberulous or pubescent. Legume elongate, subterete, with scarcely 
prominent sutures.—Guill. et Perr. Fl. Seneg. i. 259. Cathartocarpus 
conspicuus, Don, Gen. Syst. ii. 4538 fide Fl. Nigrit. 324. 
Upper Guinea. Senegambia, Sieber! Heudelot! Cayor, and on the Gambia 
(Guill. et Perr.). Sierra Leone, Don! Bagroo river (leaflets broadly pointed), 
Mann! (? A form with caducous bracts, Niger, Barter /) : ; 
Dr. Schweinfurth and Ascherson cite this species as occurring in Kordofan in their 
enumeration of Nile land plants. : 
Very nearly allied to this species is C. Fistula, very common in gardens in all tropical 
countries, and occasionally sent home by collectors from settlements in Tropical 
Africa, So far as our material enables us to judge, it differs chiefly from C. Siebervana 
in its minute bracts, which are caducous long before expansion of the flowers, so that 
the inflorescence is usnally described as ebracteate. ‘The leaflets of C. Fistula are 
usnally larger, varying to 4-6 in. in length; and the cylindrical smooth indehiscent 
legumes sometimes reach 3 ft. in length. The plant from the Niger cited above ay; 
be a small-leaved form of C. Fistula. The Bagroo form resembles, as to leaves, 
nodosa, Ham., the thickly dilated filaments of the 3 longer stamens and the shorter 
lateral racemes distinguish this species however. Cassia psilocarpa, Welw. Apout. 
Phyto-geogr. No. 40, may be C. Sieberiana. 
2. C. Arereh, Delile, Voy. & Méroé,29. Shrub or small tree, gla- 
brous in all its parts or the sepals and upper extremity of the pedicels 
faintly puberulous. Leaflets usually in 7-9 pairs, ovate to ovate-lan- 
ceolate, obtusely acuminate or more rarely broadly and obtusely pointed, 
base more or less cuneately narrowed into a petiolule or rounded, 
reticulate-venose, with prominent midrib beneath, 2-24 in. long, 10-16 
lines broad; petiolules 2-8 lines long ; common petiole without glands, 
3-1] ft. long. Racemes terminal, short or subcorymbose, the long 
slender spreading pedicels of 24-3 in. rather crowded from the axils
