24 KEPORT ON TWO BOTANICAL COLLECTIONS FROM 



Cassia insignis, N. E. Brown, sp. n. Eoliola bijuga, arapla, oblique oblonga vel 



elliptico-oblonga, breviter obtuse acuminata, venosa, glandula magna inter inferiora. 



Stipulae foliaeeae, falcato-lanceolatae. Bacernilaxesubcorymbosi. Pedicellielongati. 



Stamina perfecta 7 ; staminodia 3. Antherae perfects suba3quales, 3 inferiores 



breviter rostratse. 

 Leaves large, bijugate; petiole below the basal pair of leaflets, f-1 in. long, minutely 

 puberulous, becoming nearly glabrous ; leaflets obliquely oblong or elliptic-oblong, 

 shortly and obtusely acuminate, obliquely rounded at the base, glabrous to the eye, but 

 with a minute scattered pubescence as seen under a lens, with the veins and veinlets 

 very conspicuous on both sides ; the basal pair 1^-3| in. long, f-lf in. broad ; the terminal 

 pair 1-9 lin. distant, 2f-4j in. long, 1-2 in. broad; gland lh lin. long, 1 lin. thick, erect, 

 ovoid, obtuse, placed between the basal pair of leaflets. Stipules leafy, §-£ in. long, 

 2-4 lin. broad, falcate-lanceolate, obtuse or acute, tapering at the base into a curved 

 petiole. Bacemes loosely subcorymbose at the ends of the branches, solitary or in pairs 

 from the axils of the uppermost reduced leaves, H-3 in. long, 7-14-flowered, softly and 

 minutely pubescent. Pedicels 1-Tf in. long, pubescent. Sepals about 5^ lin. long, \ in. 

 broad, obovate, obtuse, puberulous, minutely ciliate towards the apex. Petals 8-11 lin. 

 long, 4-8 lin. broad, elliptic or elliptic-obovate, very distinctly clawed, minutely 

 puberulous on both sides. Stamens with 7 subequal perfect and 3 reduced abortive 

 anthers, 3 of the perfect anthers shortly beaked. Ovary linear, curved, densely pubescent 

 with yellowish adpressed hairs. Legume not seen. 



On the upper slopes of Mount Boraima, McDonnell 8f Quelch, 23. 



Allied to C. latifolia, G. F. W. Mey., but may be at once distinguished by its 

 narrow-based, petiolate stipules, and much longer pedicels. 



Cassia Apoucouita, Aubl. PI. Guian. i. p. 379, t. 140. 



Mazaruni Paver, 300 ft., McConnell 8f Quelch, 716. 



This appears to be the true plant of Aublet, which is easily distinguished from the 

 Brazilian plants described by Bentham as C. Apoucouita, by its narrowly winged petiole 

 and differently shaped leaflets. The C. Apoucouita of Bentham appears to me to 

 include 2 or 3 perfectly distinct species.
