pistillate flowers lowermost on the rachis ; pedicels as much as 2 mm. 

 loug; bracts small, not equalling the pedicel; sepals 5, slightly pubescent, 

 becoming at least 6 mm. loug, 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 ungiiiculate 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. populijblius, Mill., in having bracts and stipules 

 only one-third as long, in its lanceolate leaves, and in the absence of 

 petals in the pistillate 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 ; jietiole 

 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 

 flowers lowermost, apetalous ; calyx 5-fid ; lobes ovate, 3 mm. wide, 

 margin slightly reflexed ; ovary lepidote ; style bifurcate 3 times : stam- 

 inate flowers with sejials narrower than those of pistillate, with 5 petals, 

 obovate, white, densely pubescent within ; stamens about IG with fila- 

 ments pubescent at base ; no rudiment of gynoecium present in staminate 

 flower. — El Valle, Miller 8f 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 em. 

 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 : calyx deeply 5-fid ; lobes 4 mm. long, lanceolate, 

 glabrous on the inside near the base, with an acute apex : corolla and
