fascicled along the branches, 3 to 10 in a fascicle, 3 to 4 mm in 

 diameter, their pedicels pubescent, 1 to 1.5 mm long. Calyx 

 dark-brown when dry, externally slightly pubescent, the lobes 

 broadly triangular, acute, 1.5 mm wide at the base, 1.2 mm long. 

 Petals membranaceous, obovate, retuse, 1 mm long. Disk about 

 2 mm in diameter; styles 2, very short. Fruits unknown, the 

 very young ones when 1 cm long or less very slightly pubescent, 

 apparently soon entirely glabrous.

This species is manifestly allied to Ventilago dichotoma (Blanco) Merr., 

 from which it is readily distinguished by its much larger leaves.

A scandent shrub, glabrous except the stipules and the inflores- 

 cences, the branches subterete, brown when dry. Leaves pedately 

 5-foliolate, their petioles up to 10 cm long; stipules inequilateral, 

 oblong-ovate, acute to somewhat acuminate, up to 1 cm long, 

 externally densely f erruginous-puberulent ; leaflets ovate to 

 oblong-ovate, subcoriaceous, slightly shining when dry, suboli- 

 vaceous, 6 to 9 cm long, 4 to 6 cm wide, base usually rounded, 

 often inequilateral, apex rather prominently acuminate, margins 

 rather coarsely serrate-dentate; lateral nerves about 6 on each 

 side of the midrib, slencl.r, distinct; petiolules usually about 1 

 cm long. Inflorescences in the upper axils, peduncled, umbellate- 

 corymbose, cinereous-puberulent, many flowered. Flowers 

 greenish, umbellately arranged on the ultimate branchlets, their 

 pedicels cinereous-puberulent, 5 to 6 mm long. Sepals 4, lan- 

 ceolate, pubescent, acuminate, about 1 mm long. Petals oblong- 

 lanceolate, externally rather densely cinereous-puberulent, 4 mm 

 long, prominently acuminate-cor'niculate, the apical appendage 

 somewhat spreading. Filaments about 2 mm long. Female 

 flowers not seen.
