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.

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, conduplicate, 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.
