FLACOURTIACEAE 
HYDNOCARPUS Gaertner 
HYDNOCARPUS CAULI FLORA sp. nov. § Euhydnocarpus, Oliganthera. 
Arbor parva inflorescentiis exceptis glabra ; foliis late oblongis, 
chartaceis vel tenuiter coriaceis, usque ad 30 cm longis, nitidis, 
acuminatis, basi late cordato-rotundatis, nervis utrinque circiter 
15, valde prominentibus, petiolo vix 1 cm longo; inflorescentiis 
fulvo-villosis, usque ad 15 cm longis, anguste paniculatis vel 
racemosis, caulinis. 
A small tree, glabrous except the inflorescence. Branches 
slender, terete. Leaves alternate, broadly oblong, chartaceous 
or thinly coriaceous, of the same color and shining on both sur- 
faces when dry, 23 to 30 cm long, 9 to 12 cm wide, the base 
broad, rounded, somewhat cordate, the apex shortly acuminate; 
lateral nerves about 15 on each side of the midrib, very 
prominent, somewhat curved, anastomosing near the margin, 
the primary reticulations rathers lax, the ultimate ones 
slender, rather dense ; petioles stout, 5 to 8 mm long. 
Inflorescence of very narrow raceme-like panicles or of simple 
racemes fascicled on the trunk, 5 to 15 cm long, densely fulvous- 
villous. Male flowers: Pedicels stout, villous, 3 mm long, the 
subtending bracteole densely villous, narrowly oblong, 2 mm 
long. Sepals 5, free, concave, villous, rounded, about 5 mm long. 
Petals 5, free, imbricate, thinner than the sepals, elliptic, 
rounded, 3 mm long, somewhat appressed-pilose on the back, 
the basal scale cleft, the lobes reflexed, about 1 mm long. Fila- 
ments villous-bearded, 1.5 mm long. Anthers ovoid, 1 to 1.2 
mm long. Rudimentary ovary villous, small. Female flowers 
and fruits not seen. 
Mindanao, District of Cotabato, Lebak, For. Bur. 11799 Wkitford, March, 
1912, in dipterocarp forests at low altitudes. 
A very characteristic species, its inflorescence looking more like that of 
Ryparosa than of Hydnocarpus. The structure of its flowers, however, 
place it in Hydnocarpus. It is strongly characterized by its broadly oblong 
leaves which are prominently nerved and broadly rounded-cordate at the 
base, and especially by its cauline inflorescence.
