A.* Canadensis, L.i A foot or two high from deep filiform rootstocks, pubesceut : stem 

 rather slender, prolifero-dichotomous from the involucre after producing the slender- 

 peduncled primary flower, sometimes again or even again similarly proliferous from the 

 secondary involucres : leaves very veiny ; radical long-petiuled, 5-7-parted or deeply cleft 

 into narrowly cuneate divisions; these partly 2-3-cleft and incised or sharply toothed 

 toward the apex: primary involucre 2-3-leaved; secondary 2-leaved, smaller, less cut, 

 ascending : sepals hrigiit white : head of rather numerous carpels globose ; carpels hirsute 

 when young, glabrate in age, abruptly tipped with a rigid soon straight and mainly per- 

 sistent subulate style of nearly the length of the orbicular akene. — Syst. Nat. ed. 12, iii.
