Croton sp. — Pohl's 1613, 1614 in part, and 1624. In Flora Bras., 
none of these numbers is cited, nor can I find a description to 
fit the plant, which is near C. pungens. But it appears proba- 
ble that it is somewhere described. Between Guanai and 
Tipuani, Apr.—June, 1892 (1343). 
Croton Russy! Britton, sp. n. 
A large shrub or small tree; branchlets stout, marked with 
the prominent triangular leaf-scars; petioles crowded at the sum- 
mits of the branchlets, .5—1 dm. long, slender, glabrous; blades 
1-2 dm. long, .5-1 dm. broad, regularly. ovate with rounded base 
and prominent both sides; panicles in the upper axils, appearing 
as though clustered at the s ummit, 2 or 3 dm. long, narrow, on 
short stout sulcate peduncles, gray-scurfy ; bracts subulate, 1 mm. 
long; pedicels 1-2' mm. long, slender: bud depressed-globose, 
nearly 2 mm. broad ; calyx lobes 2 mm. long, ovate, acute, tomen- 
tose both sides ; petals about equalling the calyx-lobes, tomentose ; 
stamens (of st. fis. ) shorter than the petals, about 15, the filaments 
filiform, red, pubescent, the anthers globose ; ovary (of pist. fls.), 
3-lobed upon the summit, gray-scurfy, the red styles 2-cleft two- 
thirds of the way, the branches strongly recurved. 
Between Tipuani and Guanai, Dec., 1892 (1664). The same

Acalypha mollis H.B.K. Nov. Gen. 2:94. Vic. Sorata, May, 1892

ACALYPHA FLABELLIFERA Sp. n. 
Coarsely hispid-strigose and slightly ferruginous throughout;

midrib bearing about 5 additional pairs of strongly ascending pri- 
maries; staminate spikes pet I-I.5 dm. long, 4 mm. broad, 
dense, the bracts ovate ate and acute, 2 mm. long ; flowers 
I.5 mm. broad, densely pilose ; pistilate flowers at the base of the
