 claw short, broad, concave ; wing-petals obliquely lanceolate, 

 callous at the base, emarginate-bifid ; lamina concave ; petals of 

 the keel cohering in a ventricose manner, emarginate and un- 

 equally 2-lobed below, falcate at the apex, subcartilaginous-rigid, 

 whitish to pale-sulphur-greenish as is also the whole corolla,

Golungo Alto. — Not uncommon, in primitive forests and groves 

 of palms (" Die," Elaeis guineensis J acq.), along the banks of the river 

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

 oblong or 1-seeded orbicular, hispid, quite obtusely sinuate or crenate- 

 tuberculate on the sutures. Coll. Carp. 409 and 410. 



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

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

 south-west, near Musondo ; fl. Feb. 1857. A lateral branch of the 

 stem at least 30 ft. long with racemes in flower-bud, 1 Feb. 1857. Also 

 part of the same stem in fl. with fully developed leaves. No. 2241. 



According to Welwitsch this species most resembles S. ellipticum 

 Pers., but in that species the flowers are umbellate and the calyx-lobes 

 lanceolate.

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 

 lj 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- 

 versely but rather obliquely rimose, not stinging, 2- or 3- or rarely 1- 

 seeded, a little constricted between the seeds. Native name " Maxima 

 id. muxito." In the primitive forest of Quisuculo, Sobato Bango- 

 Aquitamba, rather rare ; fr. 1 to 3 Sept. 1855. Coll. Carp. 405.
