MERRILL. 
Luzon, Province of Bataan, Mount Mariveles, For. Bar. 6254 Curran, Feb- 
ruary, 1907, with nearly mature fruit, in forests at an altitude of about 550 m 
(type) : Province of Benguet, Mount Ugo, Bar. Sci. 570S Ramos, December, 1908, 
staminate flowers: Province of Abra, Tue, For. Bur. 14582 Darling, February, 
1909, sterile, altitude 1,000 m. Known to the Igorots in Abra as Baleag. 
A species manifestly allied to the Asiatic Acer laemgatum Wall., but with 
different leaves which are usually broad and rounded at the base, and with 4- 
merous staminate flowers. It is quite different from the only other species of the 
genus known from the Philippines, A. philippinum Merr., that species having the 
leaves very glaucous beneath, and the staminate inflorescence racemose. The 
latter species is a shrub or small tree, while the present one is a large tree. 
A third species is possibly represented by sterile material, For. Bur. 10948 
Curran, Mount Data, District of Lepanto, Luzon, the young leaves being densely 
tomentose beneath. 
SABI AGILE. 
MELIOSMA Blume. 
Meliosma monophylla sp. nov. 
Arbor parva; foliis simplicibus, alternis, oblanceolatis, integris, bran- 
neis, nitidis, nsqne ad 35 cm longis, 7 cm latis, apice acuminatis, basi 
sensim decurrento-acuminatis ; nervis utrinque cireiter 20, prominentibns, 
ascendentibus, anastomosantibus ; panicnlis terminalibns axillaribusque, 
dense ferrngineo-pnbescentibus, 15 ad 20 cm longis ; lloribus numerosis, 
minutis, ad apices ramnlorum congestis. 
A small tree, more or less ferruginous-pubescent. Branches terete, 
lenticellate, somewhat ferrugineous-pubeseent. Leaves simple, oblanceo- 
late, 20 to 35 m long, 5 to 7 cm wide, subcoriaceous, brownish when dry, 
shining, entire or with few irregular and obscure teeth above, the apex 
acuminate, the base long and slenderly decurrent-acuminate, glabrous 
on the upper surface, except on the somewhat pubescent midrib, beneath 
with scattered hairs especially on the midrib and lateral nerves; nerves 
about 20, prominent, ascending, anastomosing, the reticulations distinct ; 
petioles pubescent, 2 to 2.5 cm long. Panicles terminal and in the upper 
axils, 15 to 20 cm long, densely ferruginous-pubescent, the lower branches 
spreading. Flowers small, crowded on the ultimate branchlets, sessile, 
the bracts more or less pubescent. Outer three petals orbicular, 1.5 to 
1.8 mm long, the inner two linear, cleft, about 1 mm long. Stamens 2, 
about 1 mm long. Ovary compressed, glabrous, 2-celled, the style short, 
simple. 
Luzon, Province of Rizal, Tanay, Merrill 2339, May, 1903; Antipolo, For. Bur. 
431 Ahern’s collector, February, 1904; Montalban, For. Bur. 3406 Ahern’s col- 
lector, November, 1905, distributed as Semecarpus perrottetii March, which they 
remotely resemble. T., Malaligas. 
The first simple leaved form to be found in the Philippines, manifestly allied 
to Meliosma lancifolia Hook, f., of the Malay Peninsula, but apparently sufficiently 
distinct.
