ALABASTEA BORXEENSIA. 199- 



Britisii Xorth Borneo, Mount Kinabalu, Kiau, Clemens 

 WO-kS, November, 1915. 



This species is well characterized by its large leaves and 

 its greatly elongated racemes. It is undoubtedly allied to 

 Elaeocarpus robust in, Roxb., from which it is distinguished 

 by its larger, more numerously nerved leaves, much longer 

 racemes, and larger flowers. 



Elaeocarpus castaneus, sp. r.ov. § OanUrus. 



Arbor, ramulis junioribiis et subtus foliis ad costam n'ervos- 

 que et petiolis et inrlorescentiis uniformiter cinereo-pubeseens ; 

 foliis in siccitate castaneis, nitidis, oblongis, subcoriaceis, us- 

 que ad 15 cm. longis, nitidis, rerspicue obtuse acuminatis, basi 

 subacutis ad subrotundatis, margine distanter obscure crenu- 

 latis vel subintegris, nervis utrinque T vel 8, promirientibus ; 

 racemis numerosis, ex ramulis defoliatis, usque ad 16 cm. 

 longis, multifloris, 5-meris; sepalis lanceolatis, acuminatis. 5 

 mm. longis. utrinque pubeseentibus; petalis obovato-cuneatis, 

 leviter pubeseentibus, in dimidio superiore laciniatis, laciniis 

 circiter 25: stanunibus 25 ad 30, antheris oblongis obtusis : 

 ovario dense pubeseente, 5-loculare. 



A i]\"e, the branclilets, midrib and nerves on the lower 

 surface of the leaves, .petioles and inflorescences uniformly 

 subappressed. cinereous-pubescent. Brandies terete, glabrous, 

 reddish-brown, somewhat glaucous. Leaves oblong, castaneous 

 when dry, shining, the lower surface slightly paler than the 

 upper, 9 to 15 cm. long. 4 to 6 cm. wide, rather prominently 

 acuminate, the acumen blunt, usually minutelv apiculate, base 

 subacute to somewhat rounded, margins entire or with very 

 few, minute, widely scattered crenulations, the upper surface 

 glabrous except the sparinglv pubescent midrib, the lower sur- 

 face pubescent on the midrib and lateral nerves; petioles 2 to 

 2.5 cm. long, pubescent: lateral nerves 7 or S on each side of" 

 the midrib, prominent, curved, anastomosing, the primary 

 reticulations slender, subparallel. Racemes from the ultimate 

 branches below the leaves, numerous, spreading, uniformly 

 cinereous-pubescent. 14 to 1G cm. long, many-flowered. 

 Flowers 5-merous, their pedicels pubescent. (5 to < mm. long. 

 Sepals lanceolate, acuminate, 5 mm. lonor, 1-8 mm. wide, pubes- 

 cent on both surfaces, slightly keeled inside, the margins 

 densely einereous-puberulent. Petals obovate-cuneate, about 

 6 mm. long, the upper one-half cut into about 25 slender 

 laciniae, these arranged in about 6 phalanges, very sparingly 

 pubescent on both surfaces toward the base and on the mar- 

 gins, base cuneate. Stamens 25 to 30; filaments about 1 mm. 

 long; anthers oblong, obtuse. 1.2 to 1.5 mm. Ions', the longer 

 cell tipped with 2 or 3 short hairs. Torus about 2.5 mm. in
