prominently glandular beneath, the minute black glands being 

 distinctly visible to the naked eye. Its alliance is apparently 

 with Elaeocarpus ivrcuji, King, of the Malay Peninsula.

 utrinque eoneoloribus, in siccitate brunneis, basi acutis, apice 

 perspicue acuminatis, margin e distincte crenatis vel dcnti- 

 culato-crenatis, nervis utrinque 7 vel 8 prominentibus ; race- 

 mis ex axillis defoliatis, 15 ad IT cm. longis, adpresse pubes- 

 centibus ; floribus 5-meris, circiter 12 mm. diametro; sepalis 

 lanceolatis, acuminatis, extus parcissime pubescentibus : petalix 

 obovato-cuneatis, usque ad f in laciniis numerosis (circiter 

 30) filiformibus divisis, laciniis in phalangibus 5 dichotomis 

 dispositis; antheris obtnsis, valvulis aequalibus ; ovario parcis-

A tree, glabrous except the youngest branchlets and the in- 

 florescences. Branches' terete, smooth, grayish, not or very 

 obscurely lenticellate. Leaves subcoriaceous, oblong-elliptic, 

 13 to 17 cm. long, 5.5 to 7.5 cm. wide, of about the same color 

 on both surfaces, brown and shining when dry, the midrib on 

 very young leaves slightly pubescent, otherwise glabrous, the 

 base acute, apex rather prominently acuminate, margins dis- 

 tinctly crenate, often denticulate-glandular; lateral nerves 7 

 or 8 on each side of the midrib, prominent, anastomosing, the 

 reticulations lax ; petioles 2.5 to 5 cm. long. Eacemes numer- 

 ous, spreading, from the axils of the fallen leaves, 15 to 17 cm. 

 long, appressed-pubescent with somewhat brownish hairs. 

 Flowers numerous, 5-merous, 10 to 12 mm. in diameter, their 

 pedicels about 1 cm. long. Sepals brown when dry, lanceolate, 

 acuminate, about 6 mm. long, 2 mm. wide, externally obscure- 

 ly pubescent, margins puberulent, inside keeled and slightly 

 pubescent at the base. Petals obovate-cuneate, about 6 mm. 

 long and 5 mm. wide, narrowed to the cuneate base, the upper 

 two-thirds cut into about 30, very slender laciniae, these in 

 turn arranged in five dichotomous phalanges, margins of the 

 lower part obscurely pubescent and the base outside with a 

 few hairs, otherwise glabrous. Stamens about 35 ; filaments 

 scabrid, 1.5 mm. long, curved, anthers oblong, scabrid, 2 mm. 

 long, the cells obtuse, equal, not bearded at the tips. Disk 

 glands densely pubescent, contiguous, obscurely bilobed, form- 

 ing a prominent torus 3 mm. in diameter. Ovary ovoid, very 

 sparingly pubescent below, glabrous above, 3-celled; style 

 glabrous, 2 mm. long.
