white. Tendrils stout, 40 cm long and upward. Leaves pedate- 
palmately compound, each with 13 leaflets, the three central 
leaflets palmate, their petioles 2.5 to 3 cm long, the other 5 
leaflets on each side serially attached to a branch of the petiole 
which is 5 to 6 cm long, subscorpoid in arrangement; leaflets 
narrowly oblong to oblong-lanceolate, chartaceous, the central 
ones 18 to 20 cm long, about 3 cm wide, the outer lateral ones 
shorter, the outermost one very inequilateral, all distantly 
sinuate-toothed above the middle, subacute and somewhat in- 
equilateral at the base, or the outermost ones rounded, sharply 
acuminate at the apex, the upper surface glabrous and shining, 
the lower densely rufous-tomentose, the lateral veins distinct, 
7 to 9 on each side of the midrib; petiolules tomentose, those 
of the interior leaflets 2.5 to 3 cm long, of the outer ones pro- 
gressively shorter, the outermost leaflets subsessile. Inflores- 
cence tomentose, peduncled, the flower-bearing part 15 to 20 
cm long, the spikes 20 to 30, slender, spreading, 4 to 5 cm long. 
Flowers 5-merous, sessile, glabrous, scattered, each subtended 
by a small bracteole, the calyx shallow, 1.5 mm in diameter, 
obscurely toothed. Petals 5, oblong-elliptic, acute, 2.5 mm long. 
Anthers about 0.8 mm long. Ovary ovoid, sulcate, glabrous. 
Fruit very fleshy, pink, glabrous, ellipsoid, rounded, 2 cm long, 
with a single seed, the seed narrowly ovate in outline, acuminate, 
base rounded or slightly cordate, about 1 cm long, 3-angled, two

A most characteristic species, distinguishable by its leaf-characters from 
all forms previously described. The numerous leaflets, thirteen, are 
pedate-palmate in arrangement, the inner three with their proper petio- 
lules, the outer five on each side attached to a common branch of the 
petiole proper.
