Moist places and margin of swamps, Michigan (Lake Huron, and Sault 

 St. Marie, Dr. Pitcher !) Ohio, Maryland! to Arkansas! in the Southern 

 States mostly confined to the mountainous districts. July-Sept. — 11 Stem 

 1-3 feel high, slender, strongly striate. Leaves appearing as if in whorls of 

 six, whence the Linnaean name, allhough not strictly correct, is by no means 

 inappropriate, and ought not to be superseded ; tlie segments and rachis al- 

 most filiform. Scales of the exterior involucre 8-10, linear or oblong-linear, 

 usually about the length of the interior, rarely only 3 or 4 and almost as long 

 as the rays. Rays bright yellow, 8-12 lines long, narrow ; in the cultivated 

 plant sometimes oblong-oval, obtuse and deeply 2-3-toothed.
