A species manifestly allied to Trichosporum philippinense O. Ktze., 
with which the three specimens above cited have previously been confused, 
and which they greatly resemble, especially in vegetative characters. The 
flowers, however, are very different, relatively much shorter and broader, 
while the peduncles bear but a single flower, both the peduncles and 
pedicels being longer in the present species than in T. philippinense O. Ktze. 
TRICHOSPORUM IRIGAENSE sp. nov. 
Frutex epiphyticus, glaber, ramulis teretibus; foliis oppositis, 
petiolatis, coriaceis, oblongo-lanceolatis vel ovato-lanceolatis, 
nitidis, usque ad 9 cm longis, basi acutis, apice longe tenuiterque 
acuminatis, nervis lateralibus numerosis, densis, tenuibus, ad- 
scendentibus; floribus axillaribus, solitariis, pedicellatis, circiter 
8 em longis; sepalis oblongis, acutis, circiter 1 cm longis, 3 ad 
4 mm latis; corolla glabra, leviter inflata, plus minusve curvata. 
An epiphytic plant, sparingly branched, quite glabrous, the 
branches terete, apparently somewhat fleshy, when dry 2 to 3 
mm in diameter. Leaves opposite, coriaceous, oblong-lanceolate 
to ovate-lanceolate, 6 to 9 cm long, 2 to 3 cm wide, base acute 
or somewhat rounded, apex long and slenderly acuminate, 
straight or slightly falcate, the upper surface olivaceous, shining, 
the lower paler; lateral nerves 10 or more on each side of the 
midrib, slender, densely arranged, sharply ascending, about 
equally evident on both surfaces; petioles 10 to 12 mm long. 
Flowers axillary, solitary, apparently red, quite glabrous, about 
8 cm long, their pedicels about as long as the petioles. Calyx 
lobes nearly free, oblong, acute or obtuse, about 1 cm long, 
38 to 4 mm wide, narrowed at both ends. Corolla somewhat 
inflated, slightly curved, when flattened out about 7 mm in 
diameter, enlarged upward. 
Luzon, Province of Camarines, Mount Iriga, on trees at the summit, 
altitude about 1,200 m, Bur. Sct. 22211 Ramos, December 3, 19138. 
The alliance of this species seems to be with TRICHOSPORUM FOX- 
WORTHYI (Krinzl.) Aeschynanthus foxworthyi (Kranzl.), but is suf- 
ficiently distinct. The slender ascending nerves are characteristic.
