Type specimen: Mount Mariveles, Province of Bataan, Luzon (3872 

 Merrill), August, 1904. A small tree rather common on exposed forested 

 ridges at an altitude of about 1,000 m. Related to Acer niveum Blume and 

 A. oblongum Wall., differing from both species in the cuneate base of the 

 leaves, from Acer niveum also in its exserted stamens, and from A. oblon- 

 gum in its racemose inflorescence. 



No species of this family has previously been reported from the Philip- 

 pines, although Acer niveum Blume is generally distributed in the Malayan 

 region, and two species of the genus are known from Hongkong.

Zizyphus inermis, sp. nov. 



A medium-sized tree with spineless branches, broadly lanceolate, oblong 

 lanceolate to lanceolate, membranous, glabrous, equilateral, evenly 3-nerved 

 leaves, and axillary short peduncled cymes but slightly longer than the 

 petioles. Branches slender, glabrous, dark brown, lenticcllate, the branch- 

 lets fulvous pubescent. Leaves 8 to 13 cm. long, 2.5 to 5 cm. wide, the base 

 acute, regular, the apex acuminate, entirely glabrous except for the slightly 

 pubescent nerves on the lower surface, strongly 3-nerved from the base, the 

 nerves continuing to the apex, unbranched, and with a pair of faint submar- 

 ginal nerves formed by the anastomosing of the transverse nerves, and not 

 more prominent than the latter, the lateral nerves numerous, spreading, 

 freely anastomosing, those outside the longitudinal nerves not more prom- 

 minent than those between the midrib and the longitudinal nerves ; petioles 

 slightly pubescent, about 1 cm. long. Cymes densely fulvous pubescent, 5 to 

 15 flowered, 1 to 1.5 cm. long, the peduncle and pedicels about 2 mm. lonjr. 

 Flowers yellowish, 5 mm. across. Sepals spreading, ovate, acute, 2.5 mm. 

 long, more or less fulvous pubescent outside. Petals oblong, 1.8 mm. long, 

 less than 1 mm. wide, cucullate. Stamens 5, the filaments 1.5 mm. long. 

 Disc glabrous, rugose. Ovary surrounded and inclosed by the disc but free,

A subscandent shrub or suberect suffrutescent plant, with very largo, 

 simple, serrate leaves 40 to 80 cm. long, and axillary congested inflorescence 

 not exceeding 7 cm. in length. Stems 1 to 2 cm. or more in diameter, 

 brown, strongly sulcate when dry, more or less hirsute. Leaves alternate, 

 membranous, glabrous or nearly so, glandular beneath, oblong-obovate, 40 

 to 80 cm. long, 20 to 40 cm. wide, the margins twice serrate, the larger 

 somewhat repand teeth at the ends of tlie lateral nerves, the whole margin 

 irregularly moderately serrate, apex short abruptly acuminate, gradually
