Shrub, 1 or so m. high; branches densely stellate — 
tomentose, cinereous or frequently yellowish, at length 
glabrous below; leaves ovate to ovate-lanceolate, 3 to 8 cm. 
long, 2 to 4 cm. wide, acute or acuminate, entire or re- 
motely and minutely denticulate-glandular, base truncate 
or cordate, soft tomentose below like the branches and in- 
florescence, puberulent above, though frequently smoothish 
and green; petioles 1 to 3 cm. long, a third to a half the 
length of the leaves; stipules obsolete ; monoecious, rarely 
dioecious; racemes 3 to 12 cm. long, nude at base; stam- 
inate raceme interrupted; pedicels 3 to 4 mm. long;

Shrub, 1 to2 m. high, current branches and petioles canescent with 
fine stellate pubescence; leaves thin, oval to oblong-ovate, 2 to 4 cm. 
long, acute or acuminate, nearly glabrous above, somewhat thinly mealy- 
pubescent below, especially on the veins, not glandular at base or on 
margins, or rudimentary glands exceptional; petioles short, 5 to 10 mm. 
long; stipules obsolete ; racemes generally bisexual, 2 to 8 cm. long, loosely 
flowered; staminate flowers with the pedicels and 5-divided calyx nearly 
glabrous; petals oblong, about equalling the sepals, ciliate, especially at 
the base; glands large and spherical; stamens 15 (12 to 18); filaments 
slender and glabrous; bracts short, setaceous, glabrous; pistillate flowers 
2 to 4,near the base of the raceme; the small bracts and 5 spreading, 
deltoid sepals glabrous, the short pedicels and ovary stellate; petals 
linear subulate or absent; gland annular or slightly 5-angled; styles 3, 
biparted, slender, about 2 mm. long; capsule oblong spherical, glab- 
rescent when old, 5 to 6 mm. wide, 6 to 7 mm. long. —In Torrey’s type 
specimen the styles are bicleft at apex, but the flowers are abnormal. 
The staminate flowers are also abnormal in that the inner circle of 
stamens are sessile and invested by a stellate membrane separating them 
from the others which are normal. — Plate 8.
