164 PROCEEDINGS OP THE AMERICAN ACADEMY 



the types of several of his species, or specimens named by him, have 

 been met with in other herbaria, especially in that of Lindley and that 

 of Schultz, Bip., the latter now a part of the large collection of Dr. 

 Cosson. As to Asters, I do not here attempt anything beyond a 

 report of the main results of the study of certain principal herbaria ; 

 and I leave the high northern and far western species out of the 

 present view. 



Besides general acknowledgments to the curators and botanists who 

 have in all cases most obligingly facilitated my researches, special 

 thanks are due to Professor Lawson, of Oxford, and Professor Eichler, 

 of Berlin, who kindly sent to Kew, for leisurely examination and com- 

 parison, one the Asters and Solidagoes of the herbaria of Morison and 

 of Sherard, the other those of Willdenow. 



1. Notes on the North American Asters in the Older Herbaria.' 



I. Species of Linnceus. 



A. SiBiRicus. Founded on Gmelin's Siberian plant. Two speci- 

 mens in the Linnsean herbarium : they belong to a robust form of 

 the species which is represented in North America by the^. montanus 

 of Richardson. 



A. DiVARicATUS. Founded, as to the plant in the herbarium, on 

 the upper part of a specimen of A. corymhosus, Ait., wanting the cor- 

 date petioled leaves, and with open inflorescence unusually foliolose. 

 But the synonyms, both of Gronovius and of Plukenet, relate to A. 

 itiflrmus, Michx., A. cornifolius, Muhl. The Linnajan name in this 

 case should subside. 



A. DUMOSUS. Herbarium specimen of the very early cultivated 

 plant, and still in cultivation as a low and far more densely bushi/ 

 plant than we find in the wild state. The figure in Hermann's Para- 

 disus referred to by Linnaeus answers well to the wild species ; that of 

 Plukenet more resembles the early cultivated form. 



A. TENUiFCfLiDS. This is founded upon an indigenous specimen in 

 the herbarium, which is well described. As I have several years ago 

 recorded, it is Nuttall's A. fiexuosus, which must give place to the 

 Linncean name. The cited figure of Plukenet (which does not well 

 correspond with Plukenet's phrase) belongs })robahhj to A. pohjphrjllus, 

 Willd. 



A. LiNARiiFOLius. Seemingly an indigenous specimen of this 

 well-known species.
