"Erect, 1-1% ft. high from a deep 

 seated perennial root or rootstock; 

 stem very rigid and brittle, abundantly 

 leafy below, the leaves diminishing up- 

 wards, all linear, plane, obtuse, and 

 with the whole plant canescently his- 

 pidulous: heads in a very lax terminal 

 corymb; bracts of involucre in 2 or 3 

 series moderately unequal; rays rather 

 few and broad, violet." Greene, Ery-

ERIGERON TENUISSIMUS Greene. 



"Perennial, very slender, 2 ft. high or 

 more, simple below, equally leafy up to 

 the inflorescence. nearly glabrous: 

 leaves filiform, 1 or 2 in. long; flowering 

 branches at summit of the stem almost 

 racemosely disposed, divaricate, 01 

 even somewhat deflexed, each having 

 1 or 2 small heads: bracts of the broad- 

 ly campanulate involucre in 2 or 3 not 

 very unequal series, the outer ones 

 strigose-pubescent: rays 30 or more, 

 purplish or bluish: achenes oblong- 

 linear, compressed, nearly glabrous."

ERIGERON BLOCHMANAE Greene. 



"Perennial, very stout, equally leafy 

 up to the close terminal corymb of 

 large purple-rayed heads; stems strong- 

 ly striate and, with the spatulate-line- 

 ai leaves, canescently-hispidulous: the 

 main cauline leaves 2 in. long or more, 

 each with a short very leafy branch in 

 its axil: corymb of 12-20 rather short- 

 peduncled heads, these more than y 2 in- 

 high, littleless than % in. broad: bracts 

 of the involucre subulate-linear, mod- 

 erately unequal, in about 3 series, their 

 pubescence white and more appressed 

 than that of the herbage of the whole 

 plant: rays 50 or 60, of moderate width 

 for the genus: achenes compressed, 

 perfectly glabrous, chestnut-brown.
