(No. 1668). A stout, very hairy and strigose form was collected near West Cody’s 
Lake, August 10 (No. 1824), 
Xanthium canadense Mill. Gard. Dict. ed. 8, no, 2 (1768). 
Not common: Cody’s Lakes, August 9; 3 miles northwest of Whitman, Septem- 
ber 19 (No. 1675), 
Rudbeckia hirta L. Sp. Pl. ii, 907 (1753).

Lepachys columnaris (Pursh) Torr. & Gr. Fl. il, 515 (1842); Rudbeckia colum- 
naris Pursh, Fl. ii, 575 (1814). : 
Thedford, June 21; Dismal River, June 27; Plummer Ford, July 3 (No, 1395), 
The form known as variety pulcherrima’ was collected near Dismal River, June 
28; Mullen, July 17 (No. 1445), 
Helianthus annuus L. Sp. V1. ii, 904 (1753), 
Not common, its place in the region being mostly taken by the next: banks of 
South Dismal River, August 12 (No. 1676). 
Helianthus petiolaris Nutt. Journ. Acad. Phila. ii, 115 (1821). 
In the typical form, the leaves are sinall, ovate and cuneate at the base. Common: 
Thedford, June 19; Grant County, near Whitman, August 3; Mullen, July 22 (No. 
1362). 
Helianthus petiolaris patens (Lehm.) Rydberg, Bull. Torr. Club, v, 334 (1894); 
Helianthus patens Lehm. Ind. Sem. Haimb, 1821, ex DC, Prodr. v, 556 (1836). 
My specimens agree fully with the description of //. patens as given in DC, Prodr., 
but I believe it should be placed as a variety of J/. petiolaris, It differs, however, 
considerably from the typical forin, approaching in many respects /T, annuus. The 
heads are as large as a middle sized H. annuus, but with the bracts of H. petiolaris. 
They are borne on long peduncles, which are more or less fleshy just below the head, 
The leaves are large, broadly ovate or subcordate as in HW, annuus, but with longer 
petioles. In a fire-break, 3 miles northeast of Whitman, August 1 (No. 1635). 
Helianthus scaberrimus Ell. Bot. 8. Car. & Georg. 423 (1824); H. rigidus Desf. 
Cat. Hort. Paris, ed. 8, 18! (1829). 
Gray cites Helianthus diffusus Sims,’ also as a synonym of H. rigidus (Cass.) Desf. 
Although the description fits approximately, the plate seems so different from our 
HA. rigidus that it must be something else. As this plant takes the name AL 
scaberrimus E1l., HT. seaberrimus Benth,’ must take the name //. bolanderi Gray .* 
Sand hills, 8 miles northeast of Whitman, July 29 to 31 (No. 1627), 
Helianthus sp. 
The head is not unlike those of JI. grosse-serratus and IT, maximiliani, but the 
leaves are very thin, on slender, margined ciliolate petioles, Only one specimen in 
bloom secured; near Cody’s Lakes, August 10 (No. 1825). 
Helianthus giganteus L. Sp. Pl. ii, 905 (1753). 
Only a few specimens belonging to this species were secured: near West Cody’s 
Lake, August 10 (No. 1669). 
Helianthus maximiliani Schrad. Ind. Sem, Hort, Gott. (1835), 
The specimens differ somewhat from the common form in that the stem is unusu- 
ally smooth and shining: West Cody's Lake, August 10; Halsey, September 11; 
Thedford, August 19 (No. 1675). Another form was seen frequently throughout 
Grant County. It must belong to the species, although the leaves were all opposite. 
The bracts of the involucre were very broad, undoubtedly monstrous, this growth
