vigorous climber with milky juice ; flowering part of the stem 1-2 lin.

beneath, and all parts of the inflorescence (except the corolla) more or 
less pubescent with short curved hairs, densest on the inflorescence. 
Leaves spreading; petiole 3-5 in. long; blade 14-5 in. long, 1-4} in. 
broad, broadly cordate-ovate, cuspidate-acuminate ; basal sinus varying 
from narrow to broad and open; both sides sprinkled with short hairs or 
glabrous except on the nerves beneath; veins conspicuously reticulate 
beneath. Panicles cymose, lateral, 14-8 in. long, including the 4-3 
in. long peduncle, formed of 2—5 alternate branches $4} in. long, each 
‘with numerous 2-4-flowered fascicles of small flowers racemosely 
scattered along them; pedicels 1-2 lin. long. Sepals }—? lin. long,

glabrous outside, retrorsely and sparsely pubescent with fine silky hairs 
on the basal part within. Coronal-lobes arising from the base of the

‘the column, and dorsally produced into radiating tubercles that are 
grooved behind or beneath and somewhat compressed into a ridge above, 
their apical part free, erect, subulate, acute, applied to the backs of the 
anthers. Style convex at the apex, slightly exceeding the anther- 
appendages, which are incumbent upon it. Staminal-column (including
