Botanical Writings of Rafinesque. 227 



" Leptopyrum (tenellum,) it belongs to the tribe of gramens, 

 and is akin to the Avena. Found in Virginia." [We have met 

 with no subsequent notice of this genus.] 



" Florkea (palusiris,) was discovered by Messrs. Marshall and 

 Muhlenberg, in Pennsylvania, and named by Willdenow. Hex- 

 andria, Digynia: natural order doubtful." 



" Forrestia (thyroides,) near akin to Ceanothus, but tri-gynous ; 

 was found by Mr. Forrest in the northern part of the State of 

 New York." [From a brief communication in an earlier volume 

 of the Medical Repository, the third of the same series, 1806, 

 p. 422, which escaped our notice in making the above cited enu- 

 meration, the locality of this plant, (Ballston Spring,) and a good 

 description are given, which leaves no doubt that this new genus, 

 the earliest of the long series published by this author, is founded 

 upon Ceanothus Americanus.] 



" Hexorima (dichotoma,) is very near to Uvularia and Strep- 

 topus ; was found by Mr. Marshall, in the Alleghany Mountains 

 of Pennsylvania." [The close alliance of this genus to Strepto- 

 pus may be inferred from the subsequent reference of ^S. roseiis 

 to the same genus. Vid. Journal de Physique, 1819, 8. p. 262.] 



" Gaissenia (verna,) akin to Trollius ; was communicated to 

 me by Drs. Muhlenberg and Gaissenheimer, who named it T. 

 Americanus. It is found in Pennsylvania." 



Then follows a list of genera, which he proposes to establish 

 upon known species. This we introduce entire, on account of 

 the evidence it affords of Mr. Rafinesque's sagacity at that early 

 period. Several of these proposed genera had indeed been long 

 established, two of them even by Linnaeus himself ; but we have 

 no reason to suppose that Rafinesque was aware of their publica- 

 tion. 



" Adlumia (cirrhosa,) which is the Fiimaria fungosa, Ait. 



Cucularia (bulbosa,) is Fnmaria Cucullaria, Linn. 



Calistachya (alba,) is the Veronica Virginica, Linn. 



Diarina (festucoides,) from the Festuca diandra, Michx. 



Kampmania (fraxinifolia,) Zanthoxylum tricarpum, Michx. 



Negundium (fraxinifolium,) Acer Negundo, Linn. 



Jacksonia (trifoliata,) Cleome dodecandra, Linn. 



Cuttera [misprint for Cutlera,] (saponaria and ochroleuca,) Gen- 

 tiana, Willd.
