florescence terminal, shortly peduncled, the peduncle and axis 

 4 to 7 cm long, the former glabrous or nearly so, the bracts 

 subtending the branches deciduous; primary branches 8 to 15, 

 racemosely arranged, 18 to 24 cm long, slightly pubescent, 

 spreading-ascending ; umbels numerous, racemosely arranged on 

 the primary branches, 8- to 12-flowered, their peduncles up to 



1 cm in length; the pedicels in flower, 2 to 3 mm long, in fruit 

 somewhat longer. Flowers 5-merous, white. Calyx obconic, 

 truncate, about 2.5 mm in diameter. Petals 5, ovate, acute, 2 

 mm long, somewhat 3-nerved. Filaments 3,5 to 4 mm long. 

 Fruits ellipsoid to oblong-ellipsoid, about 5 mm long, 5-angled 

 or sulcate, 5-celled. 



Luzon, Ilocos Norte Province, Burgos, Bur. Sci. 32912 (type) , 

 32901. Ramos, July, 1918, on rocks in dry thickets at low alti- 

 tudes. Bur. Sci. 33207 Ramos from Mount Nagapatan, Ilocos 

 Norte Province, Luzon, perhaps represents a form of the same 

 species but the leaflets are smaller, while the petioles vary from 



2 to 6 cm in length; this number was collected at an altitude 

 of about 800 meters, growing on tree trunks. 



This species is most closely allied to Schefflera brevipes Merr. 

 and is one of the very few Philippine species with short petioles. 

 It is distinguished from S. brevipes by its smaller and much 

 fewer-nerved leaflets; its much shorter inflorescence-axis, and 

 rather long-pedicelled, never subsessile, umbels.

Frutex scandens, glaber, ramulis tenuibus; foliis 6-foliolatis, 

 foliolis oblongis ad oblongo-obovatis, integris, subcoriaceis, usque 

 ad 9 cm longis, apice tenuiter acuminatis, basi acutis, nervis 

 utrinque 6 ad 8, subpatulis, perspicuis; inflorescentiis termina- 

 libus, ramis primariis circiter 4, usque ad 25 cm longis; umbel- 

 lulis circiter 5-floris, racemose dispositis; floribus 5-meris. 



An entirely glabrous vine, the ultimate branches 4 mm in 

 diameter or less. Leaves palmately 6-foliolate; leaflets subco- 

 riaceous, oblong to oblong-obovate, entire, pale when dry, shining, 

 6 to 9 cm long, 2 to 3.5 cm wide, the apex slenderly acuminate, 

 base acute; lateral nerves 6 to 8 on each side of the midrib, 

 spreading or only slightly ascending, prominent on the lower 

 surface as are the reticulations; petiolules 1 to 2.5 cm long; 

 petioles 6 to 7 cm long. Inflorescence terminal, the rachis 2 

 cm long or less, bearing usually 4 primary branches up to 25 

 cm long. Flowers 5-merous, about 5 in each umbel, their pedi- 

 cels about 3 mm long, the umbels widely scattered and racemosely
