Descr. A lofty glabrous climber. Stems stout, succulent, 
as thick as a goosequill, twining, and sparingly branched. 
Leaves small and distant for the size of the plant, shortly 
stoutly petioled, one and a half to two and a half inches long, 
ovate-cordate, obtuse, thick and succulent, nerveless, deep 
green like the stems. Peduncles axillary, short, curved, stout, 
terete, bright green, three- to four-flowered. Bracteoles small, 
subulate. Pedicels short. Calyx-lobes subulate, quarter of an 
inch long, green. Corolla two and a half inches long, curved 
at the base, two inches broad across the top; tube slightly 
inflated and green at the base, expanding into a funnel- 
shaped, five-angled, transparent limb, with opaque green 
reticulated veins; this presents five short distant lobes on 
its margin, which bears the five curious horizontal appendages 
that together form the umbraculiform cap to the flower: this 
cap is bright verdigris-green, pitted on the surface and 
formed of five confluent convex lobes with a conical central 
papilla, each lobe is two-lobed at its outer margin, and the 
margins are turned up and bear a series of transparent flat 
erect hairs within the border. Staminal corona yellow, termi- 
nating in five erect strap-shaped connivent processes with 
recurved apices.— J. D. H.
