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 scan dent 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 ferruginous-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, slender, 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-corniculate, the apical appendage 
somewhat spreading. Filaments about 2 mm long. Female 
flowers not seen.
