Sideroxylon urdanetense Elm. n. sp. 



Lofty tree; trunk 12 dm through, terete, nearly straight, 

 20 or more m high, mainly branched toward the top; 

 bark dark brown and scaling on the surface, testaceus 

 otherwise; sapwood white and burly, hard, odorless and 

 tasteless; main branches spreading, crooked, ultimately nu- 

 merously rebranched; the rigid twigs erect, much roughen- 

 ed with raised leaf scars, the apical leaf bearing portion 

 dark fulvus pubescent. Leaves clustered toward the apex of 

 the branchlets, in whorls or subalternating, also ascending, 

 quite rigid, shallowly folded upon the upper more or less 

 shining dark green surface, much lighter green beneath, glab- 

 rous except the midrib beneath, curing brown on both sides, 

 the entire edges subinvolute when dry, coarsely wavy to 

 ward the apex which terminates in a very short blunt point, 

 obtuse or broadly cuneate toward the base, the smallest oblan- 

 ceolate, the larger or normal ones oblanceolately oblong, 9 

 cm long without the petiole and one third as wide across 

 the upper one half; midrib prominently raised beneath and 

 in the fresh state yellowish brown, deeply furrowed above 

 and light yellowish green, brown when dry, short canescent 

 along the lower side; lateral nerves 9 to 11 on each side, 

 very oblique, straight except the ascendingly curved tips, 

 relatively conspicuous beneath, cross bars none or very 

 obscure; petiole 2.5 cm long, furrowed along the upper 

 side, grayish puberulent beneath, thickened toward the base, 

 usually with small buds in their axils. Flowers not seen. 

 Fruits solitary or in pairs from the leaf axils; pedicels 

 divergent, fulvus pubescent, as long as the petioles, grad- 

 ually thickened toward the distal end; nuts dark vinosus 

 when fully mature, subtended by a whorl of imbricated 

 5-segmented persistent calyx, obovoidly ellipsoid, 1.5 to 2 

 cm long, glabrous and shining, mucronately pointed at the 

 broadly rounded apex; calyx segments fulvus on the out- 

 side, rigid, almost 5 mm long, ovately rotund.
