 Nos. 3871, Sept. 17, 1914, Parkedale Farm; 484a, Aug. 31, 1892, Belle 

 Isle. Prdbahly the common form in the sovithern part of Michigan.

Helianthus giganteus Lin. Var. virgatus (Lam.) N. Comb. 



Helianthus virgatus Lam. Encycl. 3, 85, 1789. 



Helionthiis aUissmus Var. virgatus Pers. Syn. 2, 476, 1807. 



Stem slender, simple, 4 feet or less high, terminated by a single head 

 with one or two additional in the axils of as many of the uppermost 

 leaves; leaves opposite, except the uppermost, very thin and delicate, 

 lanceolate, coarsely serrate, green, nearly of the same hue on both 

 faces; pubescence copius on the upper parts, much as in the species 

 but white not rusty. Swamps. Farwell, No. 1623c, Aug. 23, 1914, 

 Stoney Creek; No. 1623b, Sept. 2, 1901, Lakeville; No. 1623a, Aug. 20,

Helianthus giganteus Lin. Var. oppositifolius N. Var. 



Stems three feet or under; leaves mainly oj^posite, some conduplicate, 

 firm, narrowh' lanceolate, acuminate at both ends, 4 or 5 inches long or 

 less, bluish green, paler below; heads few, sometimes only one, when 

 more, terminating axillary branches, forming a simple 3-6-flowered 

 corymb; pubescence appressed, only on the uppermost parts. Fields 

 at Algonac. Farwell, No. 3884, Sept. 13, 1914; No. 1623, Sept. 27, 

 1898, Birmingham. Bears about the same relation to H. giganteus as 

 H. Maximiliani Var. Dalyi (Britton), N. comb. {Helianthus Dalyi Britt. 

 Journ. N. Y. Bot. Card. 2, 89, 1901) does to H. Maximiliani. Bears 

 slender fusiform rhizomes or these ending in small tubers. 



Helianthus giganteus Lin. Var. altissimus (Lin.) N. Comb. 



Helianthus altissimus Lin. Sp. PI. Ed. 2, 2, 1279, 1863. 



Like the species but glabrous and glaucous on the stem, the branches 

 and peduncles sparsely appressed hirsute; the tips of the chaff in this 

 variety are not black as in the species; No. 3883, Sept. 13, 1914, Algonac. 



Helenium autumnale Lin. Var. grandifiorum (Nutt.) T. & G. 



In addition to the typical form wath narrow-lanceolate, entire or 

 denticulate leaves there is another wnth broadly lanceolate leaves that 

 are coarsely serrate or dentate; the achenes are shorter, broader and 

 wider above than in the former and the pappus scales are smaller and 

 longer a\^^led. It seems to be Torrey and Gray's Var. grantlifiorum.
