slightly ciliate margins, the outer three broadly ovate, obtuse, G to 7 unn. 

 long, rather strongly imbricate in biul, the inner three slightly imbricate, 

 similar to the outer ones but somewhat smaller. Stamens 2.5 mm. long, 

 glabrous, the anther cells not entirely obscured by the truncate connectives. 

 Ovaries 3, oblong, glabrous, 2 mm. long, the ovules about 8, parietal in two 

 rows. 



Type specimen: Laguimanoc, Province of Tayabas, Luzon (4021 Merrill), 

 March 12, 1905. A small tree rather common in the open hill forests, the 

 first species of the genus to be found in the Philippines. 



Unona clusiflora, sp. nov. % Dasyviaschalon. 



A shrub or small tree, with oblong-elliptical, acute or short acuminate 

 glabrous, glaucous leaves, and axillary 3-petaled flowers 3 to 6 cm. long. 

 Branches dark reddish brown, glabrous. Leaves 11 to 15 cm. long, 3.5 to 

 5 cm. wide, submembranous, pale when dry, the base acute; nerves about 

 12 on each side of the midrib, not prominent; petioles glabrous, channeled 

 above, nearly 1 cm. long. Flowers solitary, yellowish gieen. Sepals sub- 

 reniform, rounded, 2 mm. long, 4 mm. wide, sparingly cinereous pubescent. 

 Petals 3, ovate-lanceolate, 5 to 6 em. long, about 2 cm. wide, concave at 

 the base, but not at all narrowed below, tapering to the blunt apex, rather 

 densely cinereous pubescent outside, glabrous inside, their margins cohering 

 throughout. Stamens many, glabrous, 3 to 4 mm. long, the connectives 

 subglobose. concealing the linear anther cells. Ovaries indefinite, densely 

 fulvous-hirsute, linear-oblong. 1.5 mm. long, 2 to 3 ovuled; styles glabrous, 

 rather slender, about 1 mm. long. 



Type specimen: Lamao River, Province of Bataan, Luzon ( 2521 Merrill), 

 June, 1903. A small tree growing in the open forests at an altitude of 

 about 100 m. above the sea. Related to Unona dasymaschala Blume, but 

 entirely glabrous, except the flowers, also differing from that species in its 

 smaller flowers, longer styles, fewer ovules, and other characters. 



MONEMIACE^. 



Kibara depauperata, sp. nov. 



A subscandent shrub 2 to 3 m. high, with glabrous, elliptical ovate, acute, 

 broadly obscurely acuminate or subobtuse leaves, 5 to 8 cm. long, cymose, 

 axillary, pubescent inflorescence 2 to 3 cm. long, and oblong ellipsoid, gla- 

 brous, fruits 1.8 cm. long. Branches light gray, glabrous, the branchlets 

 yellowish green, glabrous, or the very young branchlets pubescent. Leaves 

 subcoriaceous, opposite, 5 to 8 cm. long, 2 to 4.5 cm. wide, the base acute, 

 the margins entire; nerves 5 to 6 on each side of the midrib, irregular, 

 anastomosing, the reticulations lax; petioles about 5 mm. long, glabrous, 

 or pubescent when young. Cymes usually solitary, with few branches, 

 few flowered, the peduncles, branches, pedicels, and receptacles uniformly 

 but not densely cinereous strigose pubescent, the peduncles and branches 

 1 cm. long, the pedicels G to 10 mm. long. Receptacles coriaceous, ovoid 

 or obovoid, 4 mm. long, becoming nearly glabrous. Tepals G. small, less 

 than 1 mm. long, acute, or somewhat obtuse. Carpels 14, pubescent, 1 

 to 1.5 mm. long. Fruits 1.8 cm. long, 1 cm. thick, glabrous, 6 to 8 sessile
