oblong-ovate to ovate-lanceolate, chartaceous or subcoriaceous 

 when dry, usually olivaceous, 3.5 to 5 cm long, 1.3 to 1.6 cm 

 wide, the base acute, the apex slenderly and sharply acuminate; 

 lateral nerves 3 or 4 on each side of the midrib, ascending, very 

 slender, often obscure; petioles about 2 mm long. Flowers 

 solitary, axillary, their pedicels rather densely hirsute, about 6 

 mm long. Calyx cleft to the base into 5, narrowly lanceolate, 

 acuminate or blunt lobes which are somewhat hirsute, about 7 

 mm long, 1.2 mm wide, 3-nerved. Corolla red, somewhat curved 

 and ventricose, 3.5 cm long, hirsute outside, the mouth somewhat 

 oblique, the lower 3 lobes broadly ovate, rounded, about 6 mm 

 in diameter, the upper two about 4 mm in diameter. Disk 

 glabrous, truncate, about 2 mm long. Ovary glabrous; style 

 hirsute. Anthers 2 mm long, connate, included, the filaments as 

 long as the corolla-tube.

Manifestly closely allied to Trichosporum rizalense, which it closely 

 resembles, differing in the indicated floral and vegetative characters. 



TRICHOSPORUM RIZALENSE sp. nov. § Haplotrichium. 



Species T. philippinense simillima et affinis, differt floribus 

 majoribus, circiter 3 cm longis, extus parce hirsutis, nervis 

 lateralibus vix obsoletis, tenuibus, adscendentibus. 



A scandent, slender, epiphyte, glabrous except the inflores- 

 cence. Branches and branchlets slender, terete, mostly light 

 gray. Leaves opposite, when fresh fleshy, when dry coriaceous, 

 elliptic-ovate, 3.5 to 4 cm long, 1.5 to 2 cm wide, the base acute, 

 the apex acute or slightly acuminate, rather pale when dry; 

 lateral nerves slender, ascending, about 4 on each side of the 

 midrib, sometimes indistinct; petioles about 3 mm long. 

 Flowers solitary, axillary, their pedicels slender, hirsute, 5 to 

 6 mm long. Calyx cleft to the base into 5, lanceolate, obtuse, 

 3-nerved lobes 5 to 6 mm long, about 1.4 mm wide, sparingly 

 hirsute. Corolla red, somewhat curved, 3 cm long, sparingly 

 hirsute outside, narrowed below, the mouth somewhat oblique, 

 2-lipped, lobes of the upper lip broadly rounded-ovate, about 4 

 mm in diameter, of the lower lip about 5 mm in diameter. Disk 

 glabrous, truncate, 1.5 mm long. Ovary glabrous ; style hirsute. 

 Anthers included, connate in pairs, 2 mm long, the filaments as 

 long as the corolla.

In general appearance greatly resembling Trichosporum philippinense, 

 differing however, among other characters, in its larger hirsute flowers.
