TRISTANIA MICRANTHA sp. nov. 
Arbor 20 m alta (fide Oro), infiorescentiis distincte cinereo- 
pubescentibus exceptis glabra; foliis oblongo-ellipticis, usque ad 
13 cm longis, obtusis vel latissime obtuse acuminatis, nitidis, 
basi acuminatis, nervis utrinque 20 ad 30, tenuibus, subtus dis- 
tinctis, anastomosantibus, in pagina inferiore minutissime punc- 
ticulatis; infiorescentiis axillaribus terminalibusque, peduncula- 
tis, laxis, usque ad 10 cm longis, partibus junioribus distincte 
cinereo-pubescentibus ; floribus circiter 2 mm longis, 5-meris, 
calycibus extus cinereo-puberulis, petalis suborbicularibus, 1.2 
mm diametro, integris, glabris; staminibus 15, filamentis bre- 
vissimis ; ovario pubescente, 3-loculare. 
A tree about 20 m high (fide Oro), glabrous except the dis- 
tinctly cinereous-pubescent infiorescences. Branches terete, 
pale brownish, the branchlets terete, smooth, reddish-brown. 
Leaves alternate, in general oblong-elliptic, 7.5 to 13 cm long, 
3 to»4.5 cm wide, shining when dry, the upper surface brownish- 
olivaceous, the lower paler and very minutely glandular-puncti- 
culate, apex obtuse to very broadly blunt-acuminate, base acu- 
minate, margins slightly recurved; lateral nerves slender but 
distinct, 20 to 30 on each side of the midrib, anastomosing with 
the distinct marginal nerves about 2 mm from the edge of the 
leaf; petioles about 1 cm long. Cymes axillary and terminal, 
lax, 5 to 10 cm long, peduncled, dichotomously branched, the 
peduncles reddish-brown, nearly glabrous, the younger parts 
rather densely cinereous-pubescent. Flowers, about 2 mm long, 
5-merous, their pedicels pubescent, 1.5 to 2.5 mm long. Calyx 
turbinate, cinerous-pubescent, about 2 mm long, the teeth 5, 
short, rounded. Petals glabrous, suborbicular, rounded, entire, 
1.2 mm in diameter. Stamens 15, in five groups of three each, 
the filaments glabrous, less than 0.5 mm long. Ovary pubescent, 
3-celled. 
Samar, near Catbalogan, For. Bur. 22877 Oro, August 18, 1914, on 
steep slopes, altitude about 400 meters, locally known as tiga busag. 
The alliance of this species is manifestly with Tristania decorticata 
Merr. which it closely resembles in many characters. It differs in its 
larger leaves; much longer inflorescences which in their younger parts are 
rather densely cinereous-pubescent; smaller flowers; and much shorter 
stamens.
