200 LEAFLETs. 
BIDENS TENUISSIMA. Very slender, widely branching, 2 to 6 
feet high, glabrous throughout: leaves mostly ternate, very thin 
and flaccid, long-petioled; leaflets broadly lanceolate, acuminate, 
remotely serrate-toothed, petiolulate, the odd one of more than 
twice the size of the lateral pair and on amuch longer petiolule: 
heads extremely small for the plant, campanulate, only 2 or 3 
lines high and nearly as broad, rayless; outer foliaceous and 
spreading involucral bracts spatulate-lanceolate, far surpassing 
the others, inner oblong, acutish, 3-nerved: achenes from 
oblong-cuneiform to cuneate-linear in each head, the outer series 
being shorter and broader, these with a pair of short teeth rather 
than awns, the inner with a pair erect upwardly barbed awns, all 
the achenes sparsely soft-hairy. 
Inhabiting moss-covered and decaying logs in swampy woods 
near Saratoga, Mississippi; collected by S. M. Tracy, 2 Oct., 1903, 
and distributed by him under n. 8,525. A gigantic ally of B. 
connata, but with almost minute heads. 
ASTER CoPELANDI. Stems clustered from a mass of intertur- 
ied small and wiry rootstocks, slender, ascending or assurgent, 
5 to 8 inches high, usually monocephalous, sometimes with 2 or 
3 subcorymbose heads ; herbage green and seeming glabrous, but 
the margins of the small lance-linear leaves from cilolate in the 
lower to sharply and closely scabrous-serrulate in the upper, the 
peduncular upper partof the stem sparsely and softly hirtellous: 
heads large for the plant, the involucres hemispherical, 4 or 5 
lines broad, the firm bracts in few series, subulate-linear, acute, 
ciliolate: rays short but rather showy, violet. 
At 6,000 feet on Mount Eddy, northern California, 7 Sept.
