16,6 Merrill: Philippine Euphorbiaceae, III 5g7 



about 3 mm long. Ovary ovoid, glabrous; styles 3, entire, 0.5 

 mm long. Capsules subglobose, about 1 cm long. Seeds about 

 6 mm in diameter. 



Panay, Antique Province, Culasi, Bur. Sci. S2U2U McGregor 

 (type) , June 3, 1918, in forests, altitude about 300 meters. The 

 same species is represented by Bur. Sci. 26228 McGregor from 

 the vicinity of Paete, Laguna Province, Luzon, June, 1915. 



This species is not closely allied to any other known Philip- 

 pine form and differs from the other species of this section 

 in its axillary inflorescences. It is easily recognized by its lax 

 inflorescences and its distinctly 3-nerved leaves, the basal nerves 

 usually extending to near the middle of the leaf. 



TRIGONOSTEMON LAXIFLORUS sp. nov. 



Frutex, partibus junioribus et subtus foliis plus minusve pu- 

 bescentibus; foliis oblongis ad oblongo-lanceolatis, circiter 25 

 cm longis, perspicue acuminatis, basi acutis, nervis utrinque 

 circiter 18; inflorescentiis $ tenuibus, laxis, axillaribus, usque 

 ad 30 cm longis; floribus paucis, longissime pedicellatis ; brac- 

 teis foliaceis, lanceolatis, 1 ad 1.5 cm longis; sepalis oblongis 

 ad oblongo-ovatis, acuminatis, ut videtur accrescentibus, 7 ad 

 11 mm longis; ovario ovoideo, pubescente; stylis 3, brevibus, 

 partitis. 



A shrub, more or less pubescent. Branches terete, glabrous, 

 about 4 mm in diameter, the younger parts somewhat pubescent. 

 Leaves oblong to oblong-lanceolate, about 25 cm long and 7 cm 

 wide, narrowed below to the acute base and above to the 

 conspicuously acuminate apex, the margins obscurely and dis- 

 tantly undulate-crenate, the upper surface glabrous, dark-oliva- 

 ceous when dry, the lower surface paler, rather softly pubescent 

 on the midrib, nerves, and reticulations, and with similar but 

 more scattered hairs on the epidermis; lateral nerves about 18 

 on each side of the midrib, prominent ; petioles 3 to 4.5 cm long, 

 pubescent when young, soon beconing glabrous. Pistillate in- 

 florescences slender, lax, rather few-flowered, long-peduncled, 

 pubescent, up to 30 cm long, the branches few, rather short, each 

 bearing from 1 to 3 very long-peduncled flowers, the branches 

 subtended by lanceolate, 1 to 1.5 cm long, leaflike bracts. Ped- 

 icels 2 to 5 cm long, thickened upward, usually with a small 

 linear-oblong bracteole. Sepals 5, oblong to oblong-ovate, acu- 

 minate, sparingly pubescent, apparently somewhat accrescent 

 and persistent, 7 to 11 mm long, 2.5 to 5 mm wide. Disk 

 glabrous, with 5, rounded, orbicular-ovate lobes. Ovary ovoid, 

 rather densely cinereous-pubescent; styles 3, about 1.5 mm long.
