feasee's catalogue.

above those usually admitted as dating from the Catalogue, 

 which might well be added to the list. Yticca glaiica, Nutt., 

 is doubtless adequately characterized, and should supersede 

 F. angustifoUa, Pursh, which is of a year later. The same 

 may be said of Dalea enncandra^ Nutt. as anterior to the 

 current D. laxijlora, Pursh. 



Of the tw^o generic names herein first printed Thuraria is 

 of course a mere synonym of Willdenow's Grindelia, But 

 SuleranfJiUSj a neat philological turn upon Aster, to which 

 they are allied, was the name for a genus Avhich w^as then in 

 need of it. And this will manifestly have to come to the 

 front ; not by virtue of its having been printed here, and 

 credited with two species; for neither of the species is 

 characterized. But w^hen, a year later, Pursh described 



them 



as species 



of Amelias^ they became recognizable. 

 And immediately Eafinesque (Am. M. jMag. ii. 268) wrote 

 and published them as tyj^es of a new genus '' Sideranthus 

 Fraser." And this name, as dating from Eafinesque, super- 

 sedes Chrysopsis^ Aplopappiis^ and I think every other 

 genus to wdiich either of the plants has ever been referred. 



The example of the Catalogue which I have copied from, is 

 that now in the Library of the Philadelphia Academy of 

 Natural Sciences. It is the copy which was sent by the 

 Messrs. Fraser to Zaccheus Collins, to whom our beautiful 

 far-w^estern genus Collinsia w^as dedicated. It had passed 

 through the hands of Nuttall, and had received one or two 

 slight corrections from his pen. Moreover,, he had written 

 liis name in ink, as the author of the Catalogue, as I have 

 indicated by brackets in this reprint. I doubt not that many 

 a botanist in America, and some in Europe, will welcome this 

 reproduction of a paper long since become extremely rare.
