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,

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.
