200 LEAFLETS. 



BiDEisrs 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 a much 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. 



AsTBE 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 part of 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. 

 1903, by Mr. Copeland ; distributed by C. F. Baker, under n. 

 3,867.
