surface dark-green, sparsely pilose especially near the margin or nearly 
glabrous, marked with conspicuous cystoliths, the under surface pale- 
green, setose on the principal veins, lepidote but destitute of cystoliths ; 
more or less tnplmeryed, but on the lower side the nerve little longer or 
even shorter than the 1 or rarely 2 more apical veins, the nerve of the 
upper side usually definitely longer than the single succeeding vein; 
stipules lanceolate, about 1 mm long.

8. Elatostema cheirophyllum sp. nov. 
Repens, radicans, caulibus pilosis : receptaeulis staminiferis pedun- 
culatis, paucifloris, bracteis exterioribus corniculatis : receptaeulis pisti- 
liferis sessilibus : f oliis parvis, . submembranaeeis, obovatis, marginibus 
1- ad 3-dentatis vel rarissime integris. 
At least sometimes monoecious: staminate receptacles upon slender 
glabrous peduncles 6 to 7 mm long; bracts about 3 mm long with short 
subapical spurs, glabrous or obscurely ciliolate, the -outer nearly orbicular, 
the apex ' broadly rounded or subtruncate, the inner pairs lanceolate ; 
flowers about 6, pedicels of different lengths in same receptacle, probably 
attaining 3 mm in length; perianth-segments 4, oblong to ovate, the 
outer 1.5 mm long, corniculate, the inner somewhat shorter : pistillate 
receptacles sessile; bracts lanceolate to ovate, pilose, shortly corniculate 
or acuminate, about 1.5 mm long; pedicels about 0.5 mm long, perianth- 
segments 3, ovate, obtuse, a little exceeding , 0.1 mm in length; achenes 
brown, in outline oblong-oblanceolate, about 0.6 mm long. 
A creeping, rooting plant, with pilose stems usually a little less than 
10 cm long : leaves with petioles 1 mm long or less, the submembranaceous 
lamina obovate, usually 8 to 13 mm long and 4.5 to 7 mm wide, but many 
much smaller, the base of the upper side acute, that of the lower extend- 
ing beyond the upper, hardly forming an auricle, rounded or almost 
acute; smaller leaves often- entire or nearly so, but the larger with 1 or .2 
teeth on the upper margin and 2 or 3 teeth on the lower, the teeth coarse 
for the size of the leaf, the general directions of the sinuses making an 
angle of from 10 to 45 degrees, the apical teeth obtuse, the lower often 
acute, the terminal tooth oblong to ovate, very obtuse or barely acuminate ; 
upper surface with conspicuous cystoliths, the lower lepidote, pilose on 
the veins, without cystoliths ; triplinerved, but the nerve of the lower side 
little longer than the succeeding, additional veins 1 or 2, rarely 3 ; stipules 
oblong or oblong-oblanceolate, nearly 2 mm long, subpersistent, obtuse or 
apiculate.
