Helianthus montk'ola Small. 



A form with the lower leaves of an ovate outline and the upper leaves 

 with a very broad clasping base. Near Rochester, No. 1-331, July 15, 

 1916. 



Helianthts scaberrimus Ell. 



Found at River Rouge by Billington, Chandler & Gladewitz, who 

 reported it as //. snhrhomhoideus Rydb. The involucral scales, however, 

 are mainly obtuse, which would i)lace it here. No. 4380, August 17, 

 1916. I have also collected it in Houghton Co., No. 3087, August 24, 

 1912. 



Artemisia longifolia Nutt. 



Found in considerable quantities near River Rouge. Farwell and 

 Chandler, No. 4379, August 17, 1916. 



HiERACIUM aurantiacum Liu. 



Ballast grounds at Detroit, rare, No. 4315, July 11, 1916. Has been 

 found also by Billington, Chandler and Gladewitz. 



HiERACIUM VENosuM I.in. var. sitbcaulescens, T. and G. 



Near Tacoma, No. 4264, July 2, 1916. 



ADDENDA. 



The plant mentioned above under Viola pedatifida proves to be the 

 /'. pedata var. lineariloha, DC. with very narrow or almost filiform lobes 

 to the leaves. 



Pyrola asarifolia, Mx. var. ovata, N. name. 



Since the Pyrola incarnata Fisch. is an Asiatic plant and a variety of 

 the European P. rotundifolia Lin., the plant listed above as P. asarifolia 

 Mx. var. incarnata should receive a new name and I propose for it the 

 varietal name ovata. 



Parke, Davis Co., Detroit, Mich.
