Mich. 2. p. 93. Pursh, 2. p. 508. 



On the somewhat questionable authority of Pursh, (I mean questionable 

 as regards the habitat of his species,) I have introduced this plant, which he 

 •mentions as having been collected in Carolina by Mr. Fraser. Michaux 

 discovered it in the prairies of the Illinois. The plant which under this 

 name I shall describe, I received from my friend Dr. Torrey, of New- York. 

 It was collected near the shores of Lake jVlichigan, and although by a many 

 flowered involucrum, and the want of pubescence, it varies from the des- 

 cription of Michaux, it yet resembles his plant in too many respects to be 



hastily separated from it. 



Root tuberous. Stem one to two feet high, slender, glabrous 



Leaves 



linear and linear lanceolate, long, narrow, glabrous; the upper leaves pubes- 



cent along the margin, the lower ones attenuated very much at base 

 Flowers few, (five to eight) in a terminal spike. Involucrum long, cylin- 



Scales oblong, rounded at 



Corolla 



drical, containing fourteen to twenty florets. 



the summit, and abruptly acuminate, pubescent along the margin. 



bright pHtple, sprinkled with glandular dots. Paj}pm conspicuously 



feathered. 



Grows in woods and meadows — Pursh,

This species, which was discovered by Michaux in the prairies of IlHnoiSf 

 is mentioned by Pursh as growing also in Carolina. I have not seen it tn 

 this country, and the Anon, Ramos, of Walter^ which Pursh has quoted as 

 a synonyrae, and which perhaps formed his authority for placing it among 

 our plants, belongs, I think, to a very diflerent species.
