umbellatis, ramis primariis 4 vel 5, 1 ad 1.5 cm longis; floribus 

 in ramulis primariis in triadibus dispositis, lateralibus breviter 

 pedicellatis, 6-meris, teretibus, infra leviter inflatis, circiter 5 

 cm longis, segmentis crassis, linearis, tubo circiter 6 mm longo. 



A parasitic glabrous shrub, the branches stout, apparently- 

 fleshy when fresh, terete, smooth, shining, brownish-olivaceous 

 when dry, about 1 cm in diameter, the branchlets longitudinally 

 striate. Leaves ternate or subternate, oblong to oblong-elliptic, 

 coriaceous, 8 to 10 cm long, 3 to 4 cm wide, shining, smooth, 

 the upper surface somewhat olivaceous, the lower paler, apex 

 obtuse, base cuneate; lateral nerves about 6 on each side of the 

 midrib, slender, obscure, often obsolete or nearly so; petioles 

 2 to 2.5 cm long. Inflorescences terminal and in the uppermost 

 axils, peduncled, umbellate, the peduncles about 3 cm long, the 

 primary branches 4 or 5, 1 to 1.5 cm long, each bearing at its 

 apex a triad consisting of one central sessile flower and two 

 lateral short-pedicelled ones, each subtended by a broadly ovate, 

 obtuse, 2.5 mm long bract, the lateral pedicels 4 to 5 mm long. 

 Flowers greenish-yellow, 6-merous, about 5 mm long. Calyx 

 cylindric, 6 mm long, the limb truncate, produced about 1.5 mm. 

 Corolla inflated in the lower 1 cm, terete, the lobes 6, united 

 for the lower 6 to 7 mm, the free parts abruptly narrowed, 

 linear, thickened, the reflexed part above the insertion of the 

 filament about 10 mm long and 2 mm wide, thickened, promi- 

 nently bicarinate inside by the extended margins, obtuse, slightly 

 widened upward, linear. Filaments 4 to 5 mm long, the anthers 

 continuous, linear, 7 to 8 mm long. 



Luzon, Ilocos Norte Province, Burgos, Bur. Sci. 27323 Ramos, March 10, 

 1917, on trees in forests at low and medium altitudes. 



A remarkable species, well characterized by its rather long-peduncled, 

 lax, umbellate inflorescences, the primary rays few in number, each bearing 

 a single terminal triad of one sessile and two shortly pedicelled, 6-merous 

 flowers, which are about 5 cm in length. It belongs in the group that Van 

 Tieghem characterized as Stemmatophyllum, but is not at all closely allied 

 to the other species belonging here, such as Loranthus haenkeanus Presl, 

 L. curranii Merr., etc.
