5. B. LAXA Benth. in Hook. Nig. Flor. 394 (1849). 



Hab. Niger : Vogel, 148 ! Fernando Po : Mann, 200 ! Oban : 

 Talbot, 51 ! Kamerun : Stauclt, 549 ! 4090! 4272! Preuss, 1367 !— 

 a broad-leaved form ; Bates, 390 ! a form with small stipules and 

 short, rather dense inflorescences, the latter probably due to im- 

 maturity. Hbb. Mus. Brit, and Kew. 



The mature flowers, as seen in Talbot's plant, are among the 

 largest in the genus, measuring from 2 cm. to 2-5 cm. in length. 



6. B. pedicellata, sp. nov. B. laxa Benth. var. ? pedicellata 

 Hiern in Oliv. Fl. Trop. Afr. iii. 85. 



Inflorescentia longa thyrsoidea laxissima floribus pro genere 

 longissime pedicellatis. 



Hab. St. Thomas Is., West Africa: Mann, 1068 ! Hb. Kew. 



Frutex ramulis sparse pubescentibus foliis angustis oblongis 

 ca. 12 cm. x 3 cm. utrinque angustatis glabris nisi super venas 

 appresse pilosis petiolis ad 1 cm. longis, stipulis glabris lanceolatis 

 1 cm. longis acuminatis vix vaginantibus inflorescentia laxissima 

 cymis lateralibus paucifloris bracteis bracteolisque minutis florum

The difference from B. laxa seems to be more than varietal. 

 Apart from the shape of the leaves and the presence of con- 

 spicuous floral pedicels, the stipules are much smaller and the 

 calyx-limb well-pronounced.
