Arbor parva 10 ad 15 m alta, ramulis inflorescentiis foliisque 

 utrinque, praesertim ad nervos, griseo-stellato-puberulis ; foliis 

 chartaceis, oblongo-ovatis, acuminatis, basi rotundatis, leviter 

 inaequilateralibus, margine denticulatis ; stipulis linearis, acu- 

 minatis ; umbellis axillaribus, solitariis vel binis, 3-floris ; floribus 

 parvis, circiter 7 mm longis. 



A small tree 10 to 15 m high, sometimes less. Branches 

 slender, terete, glabrous, reddish-brown to nearly black when 

 dry, lenticellate, the branchlets rather densely stellate-puberulent 

 with grayish or sometimes brownish hairs. Leaves oblong- 

 ovate, chartaceous, 5 to 12 cm long, 3 to 5 cm wide, of nearly 

 the same color on both surfaces when dry, slightly shining, the 

 base rounded, usually somewhat inequilateral, the margins den- 

 ticulate except at the base which is entire, the apex rather 

 slenderly acuminate, the acumen 1 to 2 cm long, denticulate, 

 both surfaces rather densely gray-stellate-puberulent on the 

 midrib and lateral nerves, and with scattered, minute, stellate 

 hairs on the surface, the veins pale in contrast to the darker color 

 of the leaf ; basal nerves reaching above the middle of the leaf, the 

 lateral ones above the basal pair 3 on each side of the midrib; 

 petioles 5 to 10 mm long, rather densely stellate-puberulent; 

 stipules linear, acuminate, pubescent, nearly 1 cm long. Umbels 

 3-flowered, numerous, axillary, solitary or paired, puberulent, 

 their peduncles 5 to 10 mm long, the pedicels shorter, subtended 

 by a whorl of three or four, oblong, obtuse or acute, 5 to 6 mm

 oblong or narrowly oblong-obovate, acute or obtuse, pubescent, 

 spreading or reflexed in anthesis, 7 mm long, 2 to 2.5 mm wide. 

 Petals 5, membranaceous, glabrous, narrowly oblong-obovate,
