Shrub or small tree; branchlets rather stout, angled, ferruginous-tomentose 
with sessile stellate hairs, some short dendroid hairs present; leaves with petioles 
1-3 em. long; leaf blades lanceolate-elliptic or oblanceolate, 10-22 cm. long, 3-7 
em. wide, apex subabruptly acuminate, base acuminate and decurrent, mem- 
branaceous to chartaceous, entire to obscurely crenulate, at first sparsely papil- 
lose-puberulent above at base and along petiole, the young leaves ferruginous- 
tomentose beneath with fine stellate subappressed stellate hairs, sparse sub- 
appressed indument persisting to maturity, especially along midvein, glabrescent, 
costa slightly impressed above, elevated beneath, the primary lateral veins 19-26 
on each side, slender, slightly impressed above; inflorescences axillary, sometimes 
appearing tobe terminal with greatly reduced leaves, panicles long-pedunculate, 
1- or 2-branched, many-flowered, 5-20 cm. long, ferruginous-tomentulose, the 
small sessile hairs stellate, subappressed but with erect or spreading rays, some- 
times papillose-puberulent ; pedicels slender, 5-9 mm. long; flowers 5- or 6-parted, 
umbellate, densely papillose-puberulent, up to 7 mm. long at anthesis; sepals 
triangular, 1.3-1.5 mm. long, acuminate, orange-red punctate; petals linear- 
lanceolate, 5-7 mm. long, orange-red punctate in lines, papillose-tomentose on 
inner surface, with or without glabrous area at base, with or without papillose 
ring at base; stamens 3-4.5 mm. long; filaments 1.75-2.75 mm. long, equaling 
or slightly longer than anthers, punctate, united at base into a shallow ring; 
anthers erect or sometimes appearing versatile, lanceolate, 1.75-2.4 mm. long, 
dorsifixed one-third above base, dorsally punctate with few small reddish- 
black glands, sometimes appearing eglandular; ovary finely tomentose almost to 
base, the indument minute and appressed below, short villous above and at 
base of style mostly with branched hairs, the ovary tapering into style, often 
slightly ribbed, style about 5 mm. long; placenta subglobose, apiculate; ovules 
5-9, rather large, uniseriate, enclosed.
