ELAEOCARPUS SURiGAENSiS sp. nov. § Dicera. 
Arbor circiter 20 m alta, inflorescentiis exceptis glaber; foliis 
oblongis, coriaceis, usque ad 23 cm longis, longe petiolatis, in 
siccitate brunneo-olivaceis, breviter acuminatis, basi acutis, in- 
terdum distincte inaequilateralibus, margin , minute distanter 
cuspidato-denticulatis, nervis utrinque circiter 10, distinctis; 
racemis axillaribus, usque ad 11 cm longis, laxis, paucifloris, 
griseo-pubescentibus ; fioribus 5- vel 6-meris, circiter 7 mm 
longis, sepalis petalisque extus uniformiter adpresse cinereo- 
pubescentibus ; petalis fimbriatis, staminibus circiter 20, antheris 
2.5 ad 3.5 mm longis, muticis ; ovario dense pubescente, 3-loculare. 
A tree about 20 m high, entirely glabrous except the cinereous- 
pubescent inflorescence. Branches terete, brownish, rugose, the 
ultimate ones somewhat thickened, 5 to 10 mm in diameter, the 
petiolar scars rather prominent. Leaves alternate, oblong, co- 
riaceous, brownish-olivaceous when dry, 17 to 23 cm long, 7.5 
to 10 cm wide, subequally narrowed to the shortly acuminate apex 
and to the acute base, the base sometimes distinctly inequilateral, 
the margins distantly and obscurely cuspidate-denticulate ; lateral 
nerves about 10 on each side of the midrib, prominent, anasto- 
mosing, the reticulations rather close, distinct; petioles 2.5 to 
6 cm in length. Racemes axillary, solitary, rather numerous, 9 
to 11 cm long, rather lax, few-flowered, all parts uniformly 
appressed cinereous-pubescent, the pedicels 1 to 1.5 cm long, the 
subtending bracteoles oblong to lanceolate, 3 to 5 mm long. 
Flowers 5- and 6-merous, yellow, fragrant, perfect, about 7 mm 
long. Sepals lanceolate, narrowed upward, acute, about 7 mm 
long, outside uniformly appressed cinereous-pubescent, inside 
glabrous in the lower one-half, sparingly pubescent above. 
Petals equaling the sepals in length, oblong, slightly narrowed 
below, outside uniformly appressed-pubescent, inside along the 
median portion and margins densely pubescent, slightly so else- 
where, the upper 2 to 3 mm cut into about 15 slender fimbriae. 
Stamens about 20, their filaments 1.5 to 2 mm long; anthers 
narrowly oblong, scabrid, 2.5 to 3.5 mm long, one cell slightly 
exceeding the other, the tip slightly projecting, not awned. 
Ovary ovoid, densely pubescent, 3-celled ; style pubescent near the 
base, glabrous above, about 4 mm long. 
Mindanao, Surigao Province, near Mabini, For. Bur. 26000 Ponce, May 
11, 1916, in level rich soil at the edge of the forest, altitude about 50 meters, 
locally known as yagao-yagao. 
In general appearance this species somewhat resembles Elaeocarpus 
octopetalus Merr. and E. leytensis Merr. but belongs in a different section
