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 ; floribus 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 

 ortopetalus Merr. and E. leytensis Merr. but belongs in a different section
