(1636.) S. nodosa, Linn., var. Marilandica, Gray, Man., ed. VI., 380; Macoun, Cat. II., 354, in part.

In the edition of the manual just cited, only one form of this species is described. As we have two forms of it, that were recognized and described by Pursh, Fl. II., 419, I now reproduce them, and append to the description of Pursh that of Mr. J. Dearness, Public School Inspector of London, Ont., who first drew my attention to them, and who has grown them side by side for three years.

Leaves cordate rounded, at the base acutely serrate; petioles ciliate at the base; panicle fasciculate loose-flowered; flowers, greenish brown. The whole plant often four feet high. In flower from June to August. (Pursh.) Leaves ovate to ovate-lanceolate above; broad at base cordate to round, about equally deeply serrate. Flowers, lurid olive to brown. Usually solitary. Less than a foot high on 21st May, 1889. Time of flowering, August, September, October. (Dearness.) Damp river bank at London, Ont. (Burgess, Millman, Dearness.)

(3165.) S. lanceolata, Pursh, Fl. II., 419.

Leaves lanceolate, unequally serrate, the serratures acuminate, acute at the base; petioles naked; panicle corymbose-fasciculate. Flowers, greenish yellow. In flower from August to September. (Pursh.) Leaves lanceolate from lowest to highest; deeply and unequally serrate or toothed; acute at the base. Flowers green, tinged slightly with yellow. In flower June and July. Six or eight strong stalks from a horizontally spreading root. Four feet high on 21st May, 1889. (Dearness.) Vicinity of Belleville, Ont. (Macoun.) Biddulph Township, Middlesex Co., Ont. (Dearness.)

(3166.) 8. Californica, Cham.; Gray, Synop. Fl.L, 258.

The specimens referred here have the stems puberulent, with appressed hairs, which pass in the upper part of the stem and inflor-cscense into stalked glands. The leaves, however, are more like 8. nodosa, var. Marilandica, not being deeply serrate. China Creek, Alberni Canal, Vancouver Island, 1887; in the valley of Eagle .River at Griffin Lake, B.C. 1889.
