168 TROCEEDINGS OF THE AMERICAN ACADEMY 



of Dillenius, and on Gronov. Fl. Virg. Clayton's plant came directly 

 from the rather limited district which this species inhabits. 



A. MISER. A name to be suppressed. It was wholly character- 

 ized, not upon any plant, but upon the figure of " A. ericoides Meliloti 

 agrarice umbone" Dill. Elth. 40, t. 35, fig. 39. Even the description 

 by Dillenius must have been made mainly from the plate, for it is a 

 caricature or exaggeration of the specimen (completely identified) in 

 the Sherardian herbarium, said to be raised from New England seeds. 

 It is either a sparsely-flowered state of A. viinineiis, Lam., or a sub- 

 racemose form of A. dumosus, L. The umbonate or much protuber- 

 ant disk of the capitulum in the plate is quite fictitious (as is also 

 the "caulis crassus "), at least there is no trace of it in the specimen 

 which evidently served for the figure. Yet this umbo and the thick 

 stem give the sole diagnosis of the Linnsean species. 



A. MACROPHYLLUS is the well-known species. 



A few specimens which had not been named or not taken up by 

 LinnaBus may be passed by. Linnoeus did not well know his species 

 of Aster and of Solidago. Consequently, while retaining most of his 

 species, it is necessary to suppress three or four of his names. 



II. Species founded hy Lamarck, 1783, in Diet. i. 301-308. 



The identifications gathered at Paris in Hort. Mus. Par., the General Herba- 

 rium, and those of Tournefort and of Jussieu. The proper herbarium of 

 Lamarck at Rostock I have not been able to consult. But distinct traces 

 of all the species, with one exception, have been found at Paris. 



A. AMPLEXiCAULis. A form of A. NovcB-Anglice, L. ; but the 

 synonym from herb. Tournefort is of A. puniceiis, L. 



A. AMYGDALiNUS. The common northern form of A. umhellatiis, 

 Mill. Diet. 1759, the older name. 



A. RUBRiCAULis. The A. Icevis, L. 



A. AMCENUS. The A. puniceiis, L. 



A. PANicuLATUS. A commou and multiform northern species, the 

 A. Tradescanti, L., as to herb, and Hort. Ups. (but not of Morison), 

 comprising A. tenuifolius and A. simplex of Torr. and Gray, Flora, 

 mainly, excl. syn. Name changed by Nees to A. Lamarckianus, but 

 to be restored, being older than the homonym of Alton. 



A. SALiciFOLius. Not found, nor was the " Virga aurea Cana- 

 densis elaiior, salicis minoris folio, Nees," identified in the herbarium 

 of Jussieu. I was informed by Professor Roeper that no specimen
