272 xlvii. § c^isalpinie^: (oliver). [Cassia. 



5. C. Mannii, Olio. A glabrous tree attaining 60 ft. ; branches 

 terete, smooth. Leaves 9-15 in. long ; leaflets approximated in 1-9 

 pairs or scattered, elliptical or ovate-oblong, finely or sometimes broadly 

 acute, more or less rounded at the base, glabrous, reticulate above, 

 midrib prominent beneath, 1 |— 3 in. long, 1—1 J in. broad ; petiolules 

 2 lines. Racemes short, terminal and lateral, 2^—6 in. long, ebracteate. 

 Pedicels spreading, angular or sulcate, 1J— 2 in. long more or less. 

 Sepals membranous, elliptical or ovate-elliptical obtuse, veiny, 4—5 lines 

 long. Petals about f in. long, lamina ovate or ovate-elliptical obtuse, 

 strongly veined, with a narrow distinct claw. Longer stamens ex- 

 ceeding the petals, filaments filiform not dilated. Ovary glabrous. 

 Legume not seen. 



Upper Guinea. Princes Island, Mann! 



Dr. Welwitsch collected in the province of Cazengo, Angola, a Cassia very nearly 

 allied to C. Mannii, but differing in having obtuse and emarginate leaflets. It may 

 prove a distinct species, but the specimens hardly enable me to decide. 



6. C. Petersiana. C. Bolle in Peters 7 Mossamb. Bot. 13. Shrub ; 

 extremities rachis of the leaves and peduncles thinly pubescent pube- 

 rulous or glabrate. Leaves 5-10 in. long ; leaflets usually 6-9-jugate, 

 broadly lanceolate ovate or oblong-lanceolate, acute or acuminate, 

 rounded at the base, glabrous and reticulate above, paler with sparse 

 adpressed short hairs or glabrescent beneath, 1J— 2 J in. long, J— 1 in. 

 broad, shortly petiolulate ; common petiole thinly pubescent or nearly 

 glabrous, with a linear or subcorneal gland between the leaflets, which 

 would seem to be occasionally either deciduous or obsolete. Stipules 

 half-cordiform or -reniform, sessile, J-f in. long, deciduous or partially 

 persisting. Flowers in simple or branched corymbs or short racemes, 

 terminal and from the upper axils, forming irregular leafy or much 

 bracteate panicles at the ends of the branches. Bracts pubescent, the 

 lower broadly rotundate, subcordate, apiculate, the upper ovate, cytnbi- 

 form, with thickened gland-like curved bracteoles; the principal branches 

 of the inflorescence subtended by rudimentary or obsolete leaves, the 

 broad stipules of which are often fully developed. Pedicels J-1J in., 

 pubescent or puberulous. Sepals very unequal, the two outer much 

 smaller, thinly pubescent, three inner subpetaloid. Petals clawed, the 

 posterior smaller ; anterior exceeding the stamens. Three anterior 

 anthers much larger, linear, curved, 3-4 lines long ; four intermediate 

 dehiscing by terminal pores, three posterior abortive, cordate or ovate. 

 Ovary silky-pubescent. Legume not seen. 



Nile Land. Abyssinia (a robust pubescent form, the longer clawed elliptic-obovate 

 petals exceeding 1 in.), Schimper! 



Mozaxnb. Distr. Quirimba and Mozambique, Dr. Peters! Near Senna, Dr. 

 Kirk ! Lower Shire Valley, Dr. Metier ! 



C. Delagoensis, Harv. (Fl. Capensis, ii. 272), found at Natal and Delagoa Bay, is a 

 near ally of this species, differing, apparently, in its much smaller, narrower, and more 

 numerous leaflets, with obscure venation. 



We have a single specimen in flower only from Zambesi (Dr. Kirk), apparently very 

 nearly allied to C. Petersiana, having the same stipules, but the bracts are caducous 

 long before expansion of the flowers, and the leaflets thinly pubescent above are dis-
