long, with as many basal bracteoles; sepals lanceolate, acuminate, spreading, 14 line 
long; tube of corolla narrowly cylindrical at the base and at the summit, where it is 
spirally twisted, subventricose in the middle, subsericeo-puberulous within, 18 lines long; 
segments obovate-oblong, inequilateral, crispate on the margin, 6 lines long, 4 lines 
broad, expanded, with dextrorse convolution; stamens seated on a pilose ring at the 
lower constriction of the tube 6 lines above the base; filaments very short; anthers 
linear, sagittate, acuminate, with two obtuse parallel basal prongs; disk of 5 linear 
emarginate lobes, half as long as the 2 glabrous ovate ovaries ; follicles 2, patently diva- 
ricate, in the immature state 3 in. long, and then obsoletely torulose, afterwards perhaps 
longer and straighter; seeds many, comose.

A distinct climbing species, distinguished by its solitary axillary flower; its twining 
branchlets are slender, with axils 3 in. apart; leaves opposite, ovate-oblong, narrowed 
towards the base, and there obtuse, with a recurving channelled acute acumen, green 
above, with about 16 pairs of subimmersed divergent nerves arcuately conjoined, yel- 
lowish opake beneath, with prominulent slender nerves and reticulated veins, 3$ in 
long, 14 in. broad, on recurving petioles 6 lines long; inflorescence axillary, 1-flowered, 
on a very slender erect peduncle 12 in. long, pluribracteolate at the base, continuous 
with the pedicel, which is $ in. long; sepals acutely lanceolate, erect, 13 line long; 
corolla of a greenish-yellow colour; tube 20 lines long, narrowly cylindrical above 
and at the base, ventricose in the middle; segments obovate-oblong, inequilateral, 
5-8 lines long, 4 lines broad ; follicles 2, terete, horizontally divaricate, 3 in. long, nearly 
2 lines thick.

This specimen agrees with the drawing of Velloz. It is a scandent species, very near 
E. umbellata, has slender, flexuose, subhispidulous branches, with thickened axils 5 in. 
apart, having 3 obtuse glands on each face across the nodes, half-concealed by the hairs; 
the opposite leaves are deflected, oblong-lanceolate, narrowed at the base and there sub- 
obtuse, sharply acute at the summit, chartaceous, with very revolute margins, scabridly 
hirsute above, with divergent arching nerves, beneath ferruginously opake, pubescent 
and patently hirsute along the midrib and nerves, 6—7 in. long, 11-2 in. broad, on re- 
flexed petioles 5-6 lines long ; raceme lateral, on a suddenly deflected puberulous peduncle 
lin. long, divided above into 2 branches bearing many approximate or subumbellate 
flowers, on bracteolate pubescent pedicels 9 lines long; sepals acuminate, subpilose 
outside, margins membranaceous, 2 lines long; tube of corolla 16 lines long, narrowly 
cylindrical at its base for half its length, widening above, and there spirally twisting as 
in E. umbellata, sparsely pilose; segments rhomboidally dolabriform, 8 lines long, with 
suberenulate margins; stamens seated on the constriction of the tube; anthers acumi- 
nate, shortly bifurcate at the base; disk of 5 fleshy lobes, 2 lines long, equal to 2 ovate 
ovaries.
