by LinnfciJs, however ; but Smith has written " cordifolius verus, fide 

 Cornuti." Kulm's specimen, ticketed cordifolius by Linnoeus, is A. 

 corymhosus, Ait. ; so that Linnaeus confounded the two, and Solander 

 first distinguished them. 



A. PUNiCEUS. Specimen from Kalm ; unequivocal, as also is the 

 figure and character of Hermann, from the "puniceis caulibus" of 

 which Linnjeus drew the specific name. 



A. ANNUUS. The Erigeron annuus, 



A. VERNUS. The Erigeron vernus, not in the herbarium of Lin- 

 naeus, but taken wholly from Gronov. Fl. Virg. 



A. L^vis. Credited to Kalm and described wholly from his speci- 

 men ; it is the well-known species, in the form known as A. rubri- 

 caulis, Lam., and A. cganeus, Hoffm. 



A. MUTABiLis. No trace of it in the Linnoean herbarium, 

 although indicated as being there by the underscoring of the number 

 in Linnaeus's copy of the Spec. PI. ed. 1. The species must be dis- 

 carded as a complex one, the adduced plants being incongruous, and it 

 being now impossible to know what materials were under observation. 

 The original character, in ed. 1, 875, does not agree with " Pluk. Aim. 

 56, t. 326, p. 1," which is not to be found in Plukenet's herbarium, 

 and which may be A. dumosus or a Galatella. There Linnaeus com- 

 pares it with a species, A. serotinus, which he never published nor 

 preserved in his herbarium. Finally, in the second edition of the 

 Spec. PL, he reconstructed the character in a manner incompatible 

 with the former one, introduced before the Plukenetian synonym one 

 from Herm. Hort. Lugd. t. 67, which (on the authority of the contem- 

 porary herbaria of Royen and of Sherard) proves to be A. Icevis, L., 

 and changed the comparison to one with A. Tradescanti. The new 

 character agrees no better with either figure than these do with each 

 other. The A. mutahilis of Ait. Hort. Kew. has an earlier and good 

 name in A. Icevigatus, Lam, 



A. Tradescanti. Likewise a compound, of which the elements 

 have been variously employed ; but the name may be kept up by 

 going back to its origin, that is, to the Aster Virginianus ratnosissi- 

 t)uis serotinus, parvis Jlorihus albis Tradescanti, Morison, Hist. iii. 

 121. This, as found in Morison's herbarium and in Sherard's, is 

 the smallest flowered paniculate species, the A. fragilis Willd. (not 

 Torr. and Gray), A. leucanthemos, Desf, A. artemisicejiurus, Poir., 

 A. parvijlorus, Nees., and a part of A. tenuifolius, Torr. and Gray. 

 It is still continued in European cultivation, here and there becoming
