inatis, integris, usque ad 22 cm longis; fruciibus in capitula deiisa 
ovoidea 3 ad 3.5 em loiiga congestis, numerosis, loculis 8 vel 9. 
Scandent, glabrous tlirougliout. Leaves 8-foliolatc, petioles elongated, 
petiolules 4 to 6 cm long; leaflets oblong to elliptical-oblong, glabrous, 
coriaceous, entire, Ronie^vhat sliining, base acute, apex sliort-acummate,

of the midrib, distinct beneath, spreading-asccnding, the secondary nerves 
somewhat proniiuent. Complete inflorescence not seen, the branches, 
in fruit, very stout, 1.5 to 2 cm in diameter, 70 cm long, each bcarmg 
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 hlancoi Merr., but dijfering from that species 
in its elongated branches, larger heads and more numerously-celled fruits, those 
in S. hlanvoi being usually, if not always, 5-celled. It is apparently more closely 
allied to S. cephaloics Harms, of the Malay Peninsiila, than to S. hlancoi, but 
seems sufficiently distinct from that species. The mature fruits or heads are 
very suggestive of those of some species of Pan^anus in the group of P. fascicularis 
Lam.
