 Delamboa ; fl. Feb., fr. June 1856. No. 2240. Pods 2-4-seeded,

PuNGO Andongo. — By the loftier trees along the base of the 

 gigantic rocks of the fortified district of Pungo Andongo, on the

GoLUNGO Alto. — A shrub climbing to a great height, then pendu- 

 lous with very long twisted twigs ; stem and leaves not stinging ; 

 peduncle 4 to 6 ft. long, hanging down from a lofty tree ; ripe pods 

 racemose, 5 to 7 in. long, 1 to 1^ in. diam., cylindrical, acuminate at 

 both ends, somewhat ventricose in the middle, with numerous obliquely 

 transverse lamellate scores outside, brownish-grey, not stinging, 

 furrowed along the back, lined inside with a whitish shining quasi- 

 medullary membrane ; seeds 2 or usually 3, oblong-cylindrical, 1 to 

 l\ in. long, reddish-brown, very hard like stone, impressed along one 

 side with a deep narrow trench along the whole length. Rather rare, 

 in the primitive forests of Mata de Quisucula, near Bango Aquitamba ; 

 fr. Oct. 1855. No. 2242. In the absence of the flowers, the final 

 determination of this plant must remain uncertain. Flagelliform 

 branches attaining 30 to 40 ft., pendulous ; leaflets quite glabrous, 

 smooth-glossy, herbaceous ; pods 4 to 6 in. long, sub-cylindrical, 

 attenuate-subulate at the apex, gradually attenuate at the base, trans-
