 smooth. Leaves (only the uppermost ones of flowering-branches seen) 

 opposite, petiolate, ovate-spathulate, about an inch long, pinnatifid or 

 3— 7-toothed. Flowers axillary, solitary in the axils of the reduced 

 leaves or bracts. Pedicels |— £■ in. long. Bracteoles 2, nearly close 

 under the calyx, ovate or spathulate, 2-3 lin. long. Calyx inflated, 

 about \ in. across and f in. deep ; lobes erect, triangular, acute, 1|— 2 lin. 

 long. Corolla obliquely funnel-shaped, \\ in: long and across ; tube 

 inflated above the middle ; lobes rounded, spreading, the two upper-

Nile Land, British East Africa : Taita; by the Voi River, Ilildehrandt, 

 2493. 



Tn the Kew Herbarium there are two fragmentary specimens which probably 

 belong to this species. One is from Kilimanjaro {Johnston), and the other from 

 Kikumbuliu, in British East Africa (Scott-Elliot, 6364). Johnston's specimen has 

 been named B. natalensis, McKen (Oliv. in Trans. Linn. Soc. ser. 2, Bot. ii. 343), 

 but its flowers are less than half the size of those of that species. 



48. THUNBERGIANTHUS, Engl, in Engl. Jahrb. xxiii. 509, t. 11, 

 D — F. ( Thunbe? , giopsi?^. 



Calyx campanulate 5-toothed, upper and lateral teeth nearly equal, 

 apiculate,'the two lower connate into one with two points. Corolla-tube 

 obliquely funnel-shaped, bulging behind and rough inside ; limb nearly 

 equally 5-lobed ; lobes semicircular. Stamens 4, didynamous, anticous 

 pair longer than the posticous ; filaments smooth ; anthers attached by 

 their tips; cells unequal, the sterile much smaller than the fertile. 

 Ovary seated in a shallow disk, ovoid, 2-celled ; placentas thick, bearing 

 numerous ovules ; style slender, curved downwards, thickened towards 

 the top. Capsule ovoid, 2-celled, exceeding the calyx. Seeds (linear, 

 cuneiform, testa hyaline?). 

 Species 1, endemic.

 climbing herb with zigzag somewhat flattened stems; internodes 1^-2|- in. 

 long. Leaves opposite, petiolate ; lower ones larger, cordate-ovate, 

 2 1-3 in. long and 2-2i- in. broad, unequally and coarsely 4-toothed on 

 each side, long-acuminate, acute ; upper ones ovatedanceolate, entire ; 

 petiole J— 1 in. long, clothed with very small prickles. Flowers axillary, 

 solitary, pedicellate; pedicels 1-1^- in. long. Calyx about J in. long. 

 Corolla about 1J in. long and broad; lobes about J in. long, lower 

 slightly reflexed. Stameps included. Style slightly longer than the 

 corolla-tube. Capsule exceeding the calyx. 



Lower Guinea. Island of St. Thomas : Angolare*, Quintets, 75. 



There is a very imperfect specimen in the Kew Herbarium from Wimi, Uganda 

 (Scott-Elliot, 7919), which apparently belongs to Thunbergianthns, though the calyx 

 is nearly equally 5-lobed, and the lobes about as long as the tube.
