220 Plante Lindheimeriane. 
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.) ErtgzrRon 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. mopestum, 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 
squamelle and the fragile sete 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 Pseuderigeron.

stony prairies of the Guadaloupe and Pierdenales. April 
to August.—JIn 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.
