A species of the section Sericospermum, well characterized 

 by its elliptic, prominently nerved and reticulate, coriaceous 

 leaves, its rather dense ferruginous indumentum, and its short 

 fascicled racemes. 



Pygeum elliptic urn, sp. nov. § Sericospermum. 



Frutex vel arbor, partibus junioribus et inflorescentiis et 

 foliis subtus in costa nervisque plus minus ve castaneo-pubes- 

 centibus; foliis ellipticis, crasse coriaceis, usque ad 13 cm. 

 longis, integris, in pagina superiore minute puncticulatis, 

 obtusis vel obtuse acuminatis, basi late acutis vel leviter de- 

 currento-acuminatis, glandulis ellipticis, prominentibus, nervis 

 utrinque circiter 10, prominentibus; racemis axillaribus, fasci- 

 culatis, circiter 3 cm. longis; calycis lobis 10; ovqrio dense 

 pubescente. 



A shrub or tree, the young branchlets, inflorescence, and 

 the lower surface of the leaves on the midrib and to a less 

 degree on the nerves rather prominently pubescent with dark- 

 brown or castaneous hairs, the branches glabrous, terete, lenti- 

 cellate, dark-brown. Leaves thickly coriaceous, elliptic, 11 to 

 13 cm. long, 7 to 9 cm. wide, entire, apex obtuse or obtusely 

 acuminate, base broadly acute or somewhat decurrent-acumin- 

 ate, the glands prominent, elliptic, slightly raised on the upper 

 surface, the upper surface olivaceous, shining, the midrib 

 usually pubescent, the lower surface broAvnish ; lateral nerves 

 about 10 on each side of the midrib, very prominent, spreading, 

 slightly curved, the reticulations lax; petioles stout, pubescent, 



1 to 1.8 cm. long. Racemes axillary, fascicled, about 3 cm. 

 long, the pedicels about 1 mm. long, the bracteoles elliptic- 

 ovate, obtuse, nearly 2 mm. long, pubescent. Calyx-tube about 



2 mm. long, obconic, 2 mm. in diameter at the base, nearly

 mm. long, glabrous or with few scattered hairs.

 received from the Sarawak Museum. 



In some respects similar to Pygeum pachyplnjllum, Merr., 

 but with much longer racemes, more numerous calyx-lobes, 

 quite different indumentum, the base of the leaves very dif- 

 ferent in shape and prominently glandular, and the upper 

 surface with numerous, scattered, minute pits.
