MERRILL. 
each bearing at its apex 4 to 6 umbellately-disposed branclilets 1 to 3 
cm long, these in turn bearing the 4- to 6-fiowered umbels, the pedicels 
about 1 cm long. Calyx cup-shaped, truncate, 2 mm long. Petals 6, 
free, reflexed, glabrous, narrowly ovate, acute, 1.8 long, 1 to 1.2 mm 
wide. Stamens 6, alternating with the petals; filaments 0.5 mm long; 
anthers 1 mm long. Ovary G-celled; style conical, very short. Fruit 
suborbicular or ovoid, about 5 mm long, apiculate, 6-sulcate, the resulting- 
ridges subacute.

A most characteristic species, at once recognizable by its simple leaves, diffuse 
panicles and 6-merous flowers, the petals free, reflexed. The only other species 
in the genus with simple leaves, known to me, is Schefflera avenis (Seem.) Harms, 
from Singapore. 
Schefflera ovoidea Merrill sp. nov. § Cep halo schemer a. 
Foliolis ca. 8, glabris, oblongis vel oblongo-ellipticis, breviter acum- 
inatis, integris, usque ad 22 cm longis; fructibus in capitula densa 
ovoidea 3 ad 3.5 cm longa congestis, numerosis, loculis 8 vel 9. 
Scandent, glabrous throughout. Leaves 8-foliolate, petioles elongated, 
petiolules 4 to 6 cm long ; leaflets oblong to elliptical-oblong, glabrous, 
coriaceous, entire, somewhat shining, base acute, apex short-acuminate, 
18 to 22 cm long, 8 to 10 cm wide; primary nerves about 10 on each side 
of the midrib, distinct beneath, spreading-ascending, the secondary nerves 
somewhat prominent. Complete inflorescence not seen, the branches, 
in fruit, very stout, 1.5 to 2 cm in diameter, 70 cm long, each bearing 
about 14 ovoid dense heads 3 to 3.5 cm long. Mature heads subsessile, 
the individual fruits indefinite, 8- or 9-celled, the free portions conical, 
truncate, angular, about 2 mm long.

A species resembling Schefflera lilancoi Merr., but differing from that species 
in its elongated branches, larger heads and more numerously-celled fruits, those 
in S. lilancoi being usually, if not always, 5-celled. It is apparently more closely 
allied to S. cephalotes Harms, of the Malay Peninsula, than to blancoi, but 
seems sufficiently distinct from that species. The mature fruits or heads are 
very suggestive of those of some species of Pandanus in the group of P. fascicularis 
Lam.
