This species is one of the commonest meadow plants of the higher 

 mountains and appears in the wet meadows from near the Transition- 

 Canadian boundary up through the boreal forest zones well into the 

 alpine region ; at the highest stations the leaves become much shorter 

 and ver}^ narrow so that the plant is often overlooked, amid the grasses 

 and sedges that make up the bulk of the vegetation, unless in flower.

Rothrock reports (Rep. Wheeler's Exped., p. 364) this species 

 from the southern Sierras. Coville notes a plant collected on the 

 Death Valley Expedition (no. 2114) as growing "in a meadow closely 

 grazed by cattle, and it has the short spreading leaves and assurgent 

 stems, but not the villous achenia, commonly characteristic of A. 

 pulchelhis" (Contr. Nat. Herb., vol. 4, p. 125). But true A. pul- 

 chellus has the achenes practically glabrous as contrasted with the 

 always hirsute achenes of A. A'ivdersoni, the only other Aster of 

 similar appearance in the Sierra; hence it appears that the plant 

 of Coville 's is probably true A. pulchelhis; unfortunately as yet I 

 have had no opportunity to examine this collection. 



According to Dr. Rydberg, the true name of this species must be 

 Aster Haydcni Porter, since the combination A. pidchcllus is invali- 

 dated by an earlier combination of Willdenow, 1800.
