198 ALABASTEA BOENEENSIA. 



The alliance of this species is manifestly with Elaeocarpus 

 qlaber, Blume, of Java, of which a complete description has 

 apparently never been published. My conception of the species 

 is based largely on the figure given by Koorders, (Atlas Baum- 

 art. Java, fig. 427), which was in part drawn from Blume's 

 type material. The Bornean form differs in its larger, more 

 numerously nerved, more prominently acuminate leaves, longer 

 petioles, apparently slightly larger flowers, differently shaped 

 petals, and but very slightly pubescent ovary.

A tree, the growing tip of the branchlets and the inflores- 

 cence more or less pubescent, otherwise glabrous. Branches 

 terete, grayish-brown, the branchlets smooth, reddish-brown, 

 glabrous except the very tip. Leaves alternate, large, oblong 

 to oblong-ovate, subcoriaeeous, olivaceous and shining when 

 dry, of the same color on both surfaces, up to 27 cm. long 

 and 13 cm. wide, base broadly rounded, narrowed in the upper- 

 most part to the obtuse apex, the margins prominently crenate, 

 the sinuses apiculate-glandular ; lateral nerves about 16 on 

 each side of the midrib, prominent, anastomosing, the reticu- 

 lations lax; petioles o to 8 cm. long. Eacemes solitary, from 

 the axils of fallen leaves, 30 to 40 cm. long, sparingly pubes- 

 cent. Flowers numerous, cream-colored, 5-merous, about 1.5 

 cm. in diameter, perfect, their pedicels slightly pubescent 5 

 to 8 mm. long. Buds ovoid, slightly pubescent. Sepals in 

 ■ahthesis oblong-lanceolate, acuminate, I mm. long, 2.5 to 3 

 mm. wide, glabrous, prominently keeled within, their margins 

 puberulent. Petals obovate-cuneate, about (5 mm. long, 6 to 

 "i mm. wide above, minutely and obscurely pubescent in the 

 lower 2 mm. inside and on the margins in the lower 4- mm. 

 otherwise glabrous, the upper two-thirds cut into about 4') 

 very slender fimbriae, these arranged in about 9 phalank, \s. 

 Stamens about 40 ; filaments curved, about 2 mm. Ion"'; anthers 

 oblong, scabrid, 2.5 mm. long, the valves equal, obtuse, with 

 no terminal tuft of hairs. Disk-glands prominent, densely 

 pubescent, more or less reniform, about 2.5 mm. wide. Ovary
