quantity of long capillary fibres. Eventually, when the old 
tuber is thrown off, the new one assumes its proper direction in 
the earth, and takes the place of the old tuber. Stem terete, 
glabrous, herbaceous, simple, two to three feet long, climbing. 
Leaves broad-lanceolate, glabrous, spreading or reflexed, sessile, 
striated with parallel nerves, much and very narrowly attenuated 
into a filiform ¢endril, which it uses for support; lower leaves 
ternately verticillate, upper ones smaller and alternate. Pedun- 
cles rather short, axillary, solitary, bearing a single, drooping, 
orange-coloured flower. Sepals six, lanceolate, erecto-patent (so 
that the perianth is subcampanulate), oblong, shortly but sharply 
acuminate, moderately concave, keeled at the back ; within at 
the base having a small oblong nectariferous cavity, partially 
closed by a little ciliated scale on each side. Stamens six, free, 
erect, hypogynous, as long as the pistil, much shorter than the 
sepals. Fi/ament subulate. Anther oblong, subsagittate, fixed 
by its base to the filament. Connectivum large, separating the 
cells, which are quite marginal, and open laterally by a longi- 
tudinal fissure. Ovary oval, with three furrows and three ob- 
tuse lobes, with a depressed line down each lobe, three-celled, 
cells many-seeded : the seeds attached, in two longitudinal rows, 
to the inner angle of the cell. Style about as long as the ovary, 
divided above into three rather long recurved segments or 
branches, each tipped with an obtuse downy séigma.
