pubescent young branchlets and rachis of the short racemes. 

 Branches slender, terete, gray or reddish-brown. Leaves alter- 

 nate, firmly chartaceous, subolivaceous, shining, oblong, oblong- 

 elliptic or oblong-obovate, 10 cm long, 4 to 7 cm wide, apex 

 rather prominently acuminate, the acumen blunt, base acute 

 to somewhat rounded, not or very obscurely glandular, the mar- 

 gins distantly glandular-crenulate ; lateral nerves 8 to 13 on each 

 side of the midrib, prominent, anastomosing, the reticulations 

 lax, distinct; petioles 2 to 4 mm long; stipules ovate, obtuse, 

 about 4 mm long. Staminate racemes axillary, solitary, very 

 short, few-flowered, the rachis 1 cm long or less, usually but one 

 flower maturing at a time, the bracteoles oblong, about 4 mm 

 long, persistent, the upper inflorescences sometimes reduced to 

 mere fascicles. Pedicels up to 2.5 cm long, thickened upward, 

 slender. Sepals unequal, orbicular-obovate, margins ciliate, 

 about 3 mm in diameter. Petals free, glabrous, obovate, rounded, 

 5 to 6 mm long. Stamens about 12, the exterior nine free, their 

 filaments broad, flat, about 3 mm long, the interior three stamens 

 with their filaments united for nearly their entire length. Rudi- 

 mentary ovary none. 



Sarawak, Baram District, Baram, Hose 2UU, March, 1895. 



Apparently not closely allied to any of the previously described species, 

 well characterized by its short racemes, its short petioles, its long pedicels, 

 and its broad flat filaments. 



OSTODES MACROPHYLLUS (Muell.-Arg.) Benth. in Benth. & Hook. f. 

 Gen. PL 3 (1880) 299; Pax in Engl. Pflanzenreich 47 (1911) 18. 



Tritaxis macrophylla Muell.-Arg. in Flora 47 (1864) 482. 

 Ostodes serrato-crenatus Merr. in Philip. Journ. Sci. 4 (1910) Bot. 283. 

 Sarawak, Samatan, Foxworthy HI, May 19, 1908, known to the Dyaks 

 as tuchung. 



I consider that Doctor Pax is quite correct in reducing my Ostodes 

 serrato-crenatus to O. macrophyllus. The known range of the species is 

 now Malacca, Pahang, Borneo, Sibuyan, and the Provinces of Laguna 

 and Cagayan, Luzon.
