M. Baillon (Adansonia, vi. 208-10) refers with doubt to this genus the following 
species of which fruits are unknown. Ihave 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.? Duparquetiana, Baill. Tree. Leaves bijugate, each pinna with a single pair 
of ovate acute feaflets, about 3 in. Jong by 1-1} in. broad. Flowers sessile in slender 
geminate spikes twice as long as the leaves. Calyx Sdentate. 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 Hlephantorrhiza (E. 
Petersiana) from the Zambesi. As no fruit has been seen of the plant, it must remain 
a doubtful member of this genus, which only differs from ntada 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 Hlephantorrhiza 
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 aval 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.

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