270 xlvii. § c^salpinieje (oliver). [Cassia. 



Petiole with gland usually sessile at base. Sepals 4-6 

 lines. Pedicels often supra-axillary, £-4 i n - Leaflets 

 30-50 pairs, 4 in- long 25. C. Kirkii. 



Petiole with or without sessile glands. Leaflets 8-11 

 pairs, lower ^ in., upper umch smaller, strongly-nerved, 

 falcate. 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. 

 Leaflets 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, 1^—3 J 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 J— § 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, f-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. SSeneg. i. 259. Cathartocarpus 

 conspicum, Don, Gen. Syst. ii. 453 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. Sieberiana 

 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 

 usually 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 may 

 be a small-leaved form of C. Fistula. The Bagroo form resembles, as - to leaves, C. 

 nodosa, Ham., the thickly dilated filaments of the 3 longer stamens and the shorter 

 lateral racemes distinguish this species however. Cassia psilocarpa, Welw. Apont. 

 Phjto-geogr. No. 40, may be C. Sieberiana. 



2. C. Arereh, Delile, Voy. a Meroe, 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, 2-2 J in. long, 10-16 

 lines broad ; petiolules 2-3 lines long j common petiole' without glands, 

 f-1 ft. long. Racemes terminal, short or subcorymbose, the long- 

 slender spreading pedicels of 2J-3 in. rather crowded from the axils
