pistillate flowers lowermost on the rachis; pedicels as much as 2 mm. — 
long; bracts small, not equalling the pedicel; sepals 5, slightly pubescent, 
becoming at least 6 mm. long, possessing marginal stipitate glands; — 
petals lacking; ovary slightly pubescent, with its styles twice dichoto- 
mously divided into unequal branches: staminate flower smaller than the 
pistillate ; sepals elliptical, equalling the shortest petal ; petals 5, unequal, 
from unguiculate to spatulate or obovate, largest nearly twice the length 
of the short obovate one; stamens 6, staminodia (?) 4; filaments at base 
long-pubescent ; capsule glabrous or with few stellate hairs. — Among 
shrubs near summit of San Juan’ mt., alt. 700 m., Johnston, no. 50, Aug. 
28,1903. The upper stems possess a scattered loosely stellate pubescence, 
and some leaves are a dingy brown, while others are dark brown. This 
species differs from C. populifolius, Mill., in having bracts and stipules 
only one-third as long, in its lanceolate leaves, and in the absence of 3 
petals in the pistiilate flower. 
Croton Milleri, n. sp. Shrub 20 to 25 dm. high: leaves alternate, 
stipulate, narrowly to broadly lanceolate, 3 to 7 cm. long, 1 to 2.5 cm. 
wide, above brownish green, glabrous, minutely black-punctate, under- 
neath shining silvery-lepidote, a few scales with brown centers ; margin 
of leaf subentire ; apex acute; base obtuse or narrowly cordate; petiole 
3 to 7 mm. long; stipules setaceous, caducous, 2 mm. long: inflorescence 
terminal on short lateral leafy branches; simple spike sessile, 2 to 10 cm. 
long, often recurving; flowers pedicellate ; pedicels 2 to 4 mm. long ; 
bracts setaceous, scarcely equalling the 1-flowered pedicel ; pistillate 
lowers lowermost, apetalous; calyx 5-fid; lobes ovate, 3 mm. wide, 
margin slightly reflexed ; ovary lepidote; style bifurcate 3 times: stam- 
nate flowers with sepals narrower than those of pistillate, with 5 petals, 
obovate, white, densely pubescent within; stamens about 16 with fila- 
ments pubescent at base ; no rudiment of gynoecium present in staminate 
flower. — El Valle, Miller § Johnston, no. 229, July 18,1901, and John- 
ston, no. 48, Aug. 10, 1903. Common on the low plains between El 
Valle and Punta Mosquito. This species resembles C. elaeagnoides, Wats. 
_Pavonia cochensis, n. sp. Shrubby, prostrate, branching ; branches 
as long as 55 cm., stellate-pubescent: leaves long-petiolate, velvety stel- 
late-pubescent on both sides, ovate, cordate, 3 cm. long and 2.5 cm. wide, 
Some as broad as long, with an acute or obtuse apex; petiole 2.5 cm 
long ; stipules setaceous, 2 mm. long: inflorescence axillary, solitary } 
pedicel 1.5 cm. long: involucre about 17-leaved ; leaves setaceous, 1 cm. 
in length, pubescent : ealyx deeply 5-fid; lobes 4 mm. long, lanceolate, — 
_ glabrous on the inside near the base, with an acute apex: corolla and
