220 Planta Lindheimeriance. 



Gray, Fl. 2. p. 165. Banks of the Liano. October. Also 

 on the Brazos. " Shrubby, 6 to 8 feet high ; the perennial 

 stems half an inch thick, branching above [the branches her- 

 baceous]. Leaves few and small, [scale-like or subulate], 

 spinescent or soft, or none." Lindh. 



(626.) Erigeron Canadense /?. glabratum. E. strictum, 

 DC! Prodr. 5. p. 289, sed panicula composita expansa. 

 Prairies north of the Liano, among granite rocks. October. 

 De Candolle's E. strictum is certainly not to be distin- 

 guished as a species from E. Canadense. 



(627.) E. modestum, Gray, PL Fendl in Mem. Amer. 

 Acad. n. ser. 4. p. 68. Distasis modesta, DC, Prodr. 5. p. 

 279? Rocky soil, north of New Braunfels, and near the 

 sources of the Pierdenales. June and October. — The 

 squamellee and the fragile setae of the pappus are more numer- 

 ous than in the character of Distasis modesta, DC Our 

 plant is an undoubted Erigeron. Had it more numerous rays 

 it would fall into the section Phalacroloma, before E. tenue. 

 As it is, it belongs rather to Pseud erigeron.

 Aphanostephus ramosissimus, DC Prodr. 5. p. 310. A. 

 Riddellii, Torr. fy Gray, Fl. 2. p. 189. Dry, sandy, or 

 stony prairies of the Guadaloupe and Pierdenales. April 

 to August. — In cultivation this plant flowers abundantly 

 through the whole summer, and is quite ornamental. The 

 heads droop before anthesis ; and the white rays are usually 

 tinged with pink or purple underneath.
