Vulgo — White Plantain. Plantain-leaved Cud-weed. 

 StemA to 8 or 10 inches high. Radical leaves an inch or more in width, elliptic, 

 or spatulateovate, mucronate, strongly nerved beneath, contracted at base to a 

 narrow-margined petiole. Inner leaflets of the involucre lance-linear, acute. 



Bab. Sterile knolls, in moist grounds : frequent. Fl. April-May. Fr. May-Jufte. 



Obs. The G. plantagineum, of Authors, is a stouter plant than the G. dioicum^ 

 —and certainly affords a strongly marked variety ; but I doubt whether it can, 

 with propriety, be considered any thing more. They are both frequent, on steriU 

 banks in moist meadows and woodlands. Two or three additional species aw 

 enumerated in the U. States. 



Sub-Tribe 11. Seneciomeje. Beads never dioicous ; when hcterogamons, wit* 

 the marginal florets pistillate, mostly In a single series, the rest perfect. Corolla 

 of the pistillate florets ligulate, or rarely filiform. Anthers ecaudate. Pappm 

 setaceous, many-rayed, nearly equal.

 [Etymology obscure : said to be corrupted from PtarmicaJ 



Heads large, many-flowered, radiate. Involucre campanulate, the leaf- 

 lets somewhat in a double series, nearly equal. Style of the disk-floreU 

 with the branches pubcrulent, truncate, or terminating fn a short cone. 

 Akenes not beaked; pappus setaceous, in a single series, uniform. 

 Receptacle naked.
