diameter. Sepals thick, coriaceous, 2.5 to 3 mm long, 1.3 mm 

 wide, almost triangular, densely gray-tomentose. Petals broadly 

 oblong, densely tomentose without and within, about 10 mm long 

 and 6 mm wide, with indications of 7 or 8 principal longitudinal 

 veins ; the petals become irregularly distorted in drying and are 

 hard to straighten out. Stamens 15, arranged in groups, 1.5 mm 

 long, 0.4 mm in diameter, filaments thick and broad at the base, 

 tapering to about 0.3 mm in diameter below the attachment of 

 the anthers; total length of filament about 0.8 mm; anthers 

 ellipsoid, the inner pair smaller than the outer, 0.2-0.3 mm long, 

 connective blunt-conical, projecting beyond the anthers for about 

 0.1 to 0.15 mm. Ovary rather hemispheric, about 1.7 mm high 

 and 2 mm in diameter, densely grayish tomentose, with indica- 

 tion of division into 3 lobes. Style tapering, cylindric, about 2 

 mm long, densely grayish tomentose, about 0.4 mm in diameter 

 at the base and 0.2 mm at apex. Stigma apparently capitate and 

 glandular. Ovary 2-celled. Fruit gray-tomentose, ovoid 4 to 5 

 mm tall, sometimes with the persistent style, often somewhat 

 resinous. The two long wings oblanceolate or oblong, 3.5 to 4.5 

 cm long, 9 to 10 mm wide, with five principal distinct longitudinal 

 nerves and numerous less distinct reticulate cross veins. Wings 

 pubescent throughout. Short wings lanceolate, about 1 cm long 

 and 1 mm wide, with pubescence so dense as to obscure the longi- 

 tudinal nerves. 



Luzon, Sorsogon Province, Irosin, 16840 Elmer, August, 1916, (type). 

 Field note: "Medium-sized tree in woodlands along streams at 1,000 feet 

 facing the Pacific. Trunk terete, somewhat crooked, 2 feet thick, 40 feet 

 high, mainly branched toward the top; wood whitish on the outside, 

 moderately hard; bark thick, smoothish and chalky white blotched, 

 ochroleucous otherwise; main branches divaricate, not long but repeatedly 

 branched; leaves chartaceous, con duplicate, descending, slightly paler 

 green beneath, points recurved, fruit wings pale yellowish green, turning 

 dull purple, the nut ovoid, green or yellowish green." 



This is most nearly related to Vatica lowii King, from which it differs by 

 the smaller size of the fruit, the fewer veins to the leaf, and the much 

 larger size of the flowers. 



Several other species of this genus seem to be represented in our collec- 

 tions by sterile material. Their identification will have to wait until more 

 complete material is collected.
