4 mm long; pedicels about 5 mni long; bracts membranaceous, 
oblong-ovate, rather deciduous, up to 9 mm in length. 
Luzon, Apayao Subprovince, Mount Sulu, Bur. Sci. 28355 Fénix, May 
23, 1917, on trees along streams in damp forests, altitude about 800 meters, 
known to the Ibanags as lalannug. 
Among all the Philippine species with very large, opposite, sessile or 
nearly sessile leaves this is the most strongly characterized one. It is readily 
recognized by its narrow, rather dense, raceme-like inflorescences which are 
borne in threes at the tips of the branchlets, a type of inflorescence other- 
wise not known among the numerous Philippine representatives of the 
genus.

An epiphytic glabrous shrub, the branches and branchlets 
terete, or the latter inconspicuously 4-angled and 4 to 5 mm in 
diameter, the nodes more or less setose. Leaves opposite, thickly 
coriaceous, brownish-olivaceous, of about the same color on both 
surfaces, and somewhat shining when dry, elliptic to broadly 
elliptic-ovate, 12 to 17 cm long, 7 to 12 cm wide, base broadly 
acute to rounded, conspicuously 7- or 9-plinerved, the inner 
pair of nerves anastomosing with the midrib near the apex, the 
transverse reticulations lax, obsolete on the lower surface, ob- 
secure on the upper surface, the apex very shortly and abruptly 
rostrate-acuminate, the acumen blunt, 2 to 3 mm long and as 
wide as long; petioles stout, 1 cm long or less. Panicles terminal, 
peduncled, pyramidal, 20 to 30 cm long, the peduncle and rachis 
stout, when dry and more or less flattened nearly 1 cm wide, 
narrowly 4-winged, the wings 1 to 2 mm wide, membranaceous, 
the branches and branchlets stout and similarly winged; 
branches verticillate, the lower ones up to 10 cm in length, the 
- secondary and tertiary branchlets also verticillate. Flowers 
numerous, 4-merous, pink, their pedicels about 5 mm long, the 
bracts inconspicuous, linear-lanceolate, 2 to 3 mm long. ‘Calyx 
cup-shaped, truncate, about 4mm long. Petals 4, about 8 mm 
long. Stamens 8, equal, the filaments and anthers each about
