length and less than a I inch wide; rays of the color of cream or honey. 

 With the species but less common. Farwell No. 3801, Sept. 7, 1914. 



Solidago bicolor Lin. Var. paniculata N. Var. 



Taller, — 2^ feet high; root-leaves oblong or lanceolate 2|-3| inches 

 long by 1-1^ inches wide, coarsely dentate, acute, tapering into 

 slender, narrowly margined petioles, about twice as long as the blades 

 which are hirsute on each face with scattered, appressed short hairs 

 l)ecoming more thickly placed as they pass on to the petioles; the cjiuline 

 leaves al)out 30, the lower similar to the root leaves in shape but on 

 short petioles Ih inches or less, the more copious pubesence on the 

 under surface spreading, upper cauline similar but smaller, 1| by | 

 inch or less; infloresence paniculate, the branches 1 to 4 inches long, 

 virgate, ascending tlensely flowered; rays white. The lanceolate, acute 

 leaves and paniculate infloresence give this form a very distinct ap- 

 pearance. In fields at Algonac. Farwell No. 3903. Sept. 13, 1914. 



Solidago bicolor Lin. var. ovalis, N. Var. 



About 2 feet high. Leaves very thin, proportionately broader than 

 in any of the other varieties, the lower cauline and root leaves oval, 

 2-3 inches long, 1-lf wide, crenate-serrate on petioles of their own 

 length, the upper cauline 2 inches or under and | of inch wide or less. 

 Thyrse, simple; rays yellow fading to white. With the species but less 

 common. Farwell No. 3838 August 23, 1914. In the above varieties 

 of this species the heads are 2^ lines high and the bracts of the involucre 

 are greenish Avith a pale border giving the whole thyrse a pale or ash- 

 colored appearance. In the next two varieties the whole thyrse has a 

 yellowish appearance as the involural bracts are greenish with a yellow- 

 ish border and the heads are 3 to 3| lines high. 



Solidago bicolor Lin. Var. concolor Torr. & Gray. 



Solidago hispida Muhl. 



Solidago hirsuta Nutt. 



Similar to S. Ijicolor Lin. but the rays are a deep yellow and the 

 heads larger. In similar situations; Farwell No. 3859, Sept. 7, 1914; 

 No. 481a, August 29, 1895, Orion; No. 481b August, 1908, Detroit. 



Solidago bicolor Lin. Var. spathulata N. Var. 



One or two feet high, 15 to 18 cauline leaves below the infloresence; 

 the lowest and the root leaves oblong-spatulate, about 4 inches long by 

 \\ inches broad near the rounded apex, crenate serrate, rather abruptly 

 cuneately tapering into broadly winged petioles an inch or so long; 

 upper cauline elliptical, 1| inches or less in length by a third as wide, 

 generally obtuse; heads and rays as in the preceding variet}'. Farw^ell 

 No. 481, Sept. 12, 1886. Generally on rocky, sandy or poor soil,
