a. Tijplann. Prickles iu two rows on the margins of the 

 nutlets. E. Lappula Lehm. '' Asperif," p. 121. Ledebour, 

 "Flora Ross.," vol. iii., p. 155 



h. Consanguineian. Prickles in three rows at the base, from 

 middle to apex two rows or one. E. consdnguineum, Fischer & 

 Meyer, '' Indes Sem. Ilort. Petrop.," vol. v., p. 35. Ledebour, 

 "Fl. Ross.,'' vol. iii., p. 157. 



E. RedoicsJcii, Lehm. " x\sperif," p. 127 ; Ledeb., " Fl. Ross.," 

 vol. 3, p. 158; A. Gray, " Man. Bot.," ed. 5, p. 365. Noticed 

 by Prof. Gray as growing at St. Paul's, Minn., and on the plains 

 westward, and, therefore, likely to be met with in our intercourse 

 with the Red River country. The following species, differing in 

 the branching and in the granulate or tuberculate, or nearly 

 smooth back of the nutlets, and in the rugose or smooth sides, 

 are referred by Regel as named varieties of this species, viz. : 

 E. sfrictum, Ledeb. ; E. tenue, Ledeb.; E. Karelini, Fischer ; E. 

 oJigacanthum, Ledeb. ; E. affine, Kar. & Kir. Tt is, therefore, 

 very desirable that specimens from different localities should be 

 examined with much care. 



E. dejiexiun, Lehm. Differs by its recurved fruit pedicels from 

 E. Redouskii and E. Lappula, in both of which they are erect ; 

 prickles in a single series. E. dvjiexuin Lehm. " Asperif," p. 

 120 ; Ledeb., vol. iii., p. 154 ; Regel & Herder, '• I'l. Sera., 1869," 

 p. 30. Noticed in Hooker's •' Outlines of Arctic Distribution," 

 as occurring in N. E. America, as well as in Europe (Arctic ;ind 

 Southern) and Asia to N. E. I am not sure, however, whether 

 he means this to be identical with E. Redoioskii. Regel keeps it 

 separate. 



E. pahdunij Lehm. has extremely short, erect pedicels, (flowers 

 sub-sessile,) and is kept separate by Regel. E.patulum Hooker 

 probably different, is referred by Gray to Redowskii in •' 3Ian. 

 Bot.," ed. 5. 



Ct/noghssum officinale, Linn. Naturalized from Europe. Com- 

 mon throughout the settled portions of Ont. — G. L. ; Beloeil, 

 P. Q., 1869— Dr. J. Bell; Portland, Ont., July, 1860— Dr. 

 Dupuis, sp. Is naturalized throughout the United States, south 

 as far as N. Carolina. 



C. Virginicum, Linn. Indigenous. Montreal — Dr. P. W. 

 Maclao-an ; Beloeil — Dr. Bell. Abundant in pine woods east 

 from Castleton, Ont.— Mr. Macoun. Extends south to Florida. 

 C. Morisoni, D. C. Racemes numerous, slender, divaricate,
