M. Baillon (Adansonia, vi. 208-10) refers with doubt to this genus the following 

 species of which fruits are unknown. I have not matched his descriptions with any 

 specimens at Kew. 



E. ? durissima, Baill. A tree 30-40 ft. Leaves bijugate, with about 9 pairs of 

 elliptic-oblong leaflets to each pinna, leaflets | in. long, 4-5 lines broad. Spikes 2-3 

 times shorter than the leaves. Calyx 5-fid, pubescent. Anther-cells divergent above. 

 Ovary densely villous, with a short style. 



Senegambia, Heudelot and Perrottet. 



E.f Duparquetian'a, Baill. Tree. Leaves bijugate, each pinna with a single pair 

 of ovate acute leaflets, about 3 in. long by 1-1 J in. broad. Flowers sessile in slender 

 geminate spikes twice as long as the leaves. Calyx 5-dentate. Petals connate below. 

 Stamens much exserted. Gaboon river, M. Duparquet. 



Specimens in flower, without leaf or pod, are in the Kew Herbarium, from Zomba 

 near Lake Shirwa, Zambesi land, collected by Dr. Meller. They may belong to a new 

 species. The spikes of (yellow) flowers are wholly glabrous, 5-9 lines long, and occa- 

 sionally collected in fascicles of 10-15 or more, sometimes solitary. The flowers are 

 shortly pedicellate, the pedicel separating by articulation a minute interval from the 

 rachis. Calyx-lobes deltoid. Ovary subsessile-glabrous. 



Dr. C. Bolle, in Dr. Peters' Mossamb. Bot. 9, describes a new Elephantorrhiza (E. 

 Petersiana) from the Zambesi. As no fruit lias been seen of the plant, it must remain 

 a doubtful member of this genus, which only differs from Entada in the continuous 

 valves of the legume, which separate each from the replum in one piece and not in 

 1 -seeded articles. I have not seen a specimen. All the specimens of Elephantorrhiza 

 in the Kew Herbarium are from South extra-Tropical Africa. 



4. PIPTADENIA, Benth. ; Benth. et Hook. f. Gen. Plant, i. 589. 



Flowers 5-merous, sessile or shortly pedicellate. Calyx campanulate, 

 free, toothed or lobed. Petals oval or oblong, free to the disk (in 

 Trop. African species), valvate. Stamens 10, free, exserted; filaments 

 consolidated at base with the disk and base of the petals; anthers 

 small, roundish, with a large caducous apical gland ; pollen-granules 

 oo . Ovary subsessile, with several or indefinite ovules. Legume shortly 

 stipitate, flat, coriaceous, 2-valved, valves continuous, entire. Seeds 

 compressed (winged in P. africana). — Trees or shrubs, unarmed (or 

 aculeate. Leaves bipinnate ; leaflets small, numerous ; rachis with or 

 without glands. Flowers small, white or greenish-yellow, hermaphro- 

 dite or polygamous, spicate in the following species ; spikes panicled 

 from the upper axils. 



A considerable genus in Tropical America. The following species appear peculiar 

 to Africa. 



Pinnae alternate 10-13 on each side, leaflets \ iu. or less, 30-60- 



jugate i. p. africana. 



Pinna? 4-6-jugate, leaflets 8-1 3-jugate 2. P.? Mannii. 



1. P. africana, Hook. f. Fl. Nigrit. 330. A tree of 15-30 ft. or 

 more with a widely spreading crown ; branches unarmed, early glabrous. 

 Leaves J ft. long more or less (3-7 in.), rachis puberulous eglandular ; 

 pinnae alternate, usually 10-13 on each side; leaflets opposite, multi-
