236 Botanical Writijigs of Rafinesque. 



Tracts in the Western Revieto, about the year 1820. Among 

 them is a Monograph of North American Roses ; in which thir- 

 ty-three species indigenous to the United States are described ! 

 Also a Monograph of Housto?iia, in which fourteen species are 

 described, exclusive of the Hedyotis crassifoha of his Florula Lu- 

 doviciana, of which he forms a new genus ! These tracts, with 

 another on the classification of some natural famihes, have been 

 reprinted in the fifth, sixth, and seventh volumes of the Ajinales 

 Generates des Sciences Physiques, at Brussels. — The following 

 are unknown to us. 



1821. " Western Minerva ; several new genera; suppressed 

 by my rivals!" 



1822. " The Cosmonist, twenty numbers, Lexington. — New 

 Plants of Kentucky." 



1823. " Prenanthes Opicrina, and other plants, Cincinnati." 



1824. " Floj^ula Kentuckensis and Prodromus N. sp., Lexing- 

 ton." No intimation is given of the place or form of publication. 



1824. First Catalogues and Circulars of the Botanic Garden 

 of Transylvania University, Kentucky. 



1825. Neogenyton, or indication of sixty-six new genera of 

 plants of North America. — A loose sheet of four pages, printed at 

 Lexington ; and we believe reprinted in Seringe's Bulletin. A 

 few good genera are indicated in this tract, but not properly char- 

 acterized. The best are, Cladrastis (Yirgilia lutea ; upon which 

 he endeavors to establish three or four species,) and Stylipus. A 

 few are good, but anticipated by other authors ; such as Helichroa 

 (in which some seven or eight species are made out of at most 

 three,) which is Echinacea of Mosnch ; and Megadenus, which 

 is Eleocharis of Brown ; several others may be found to indicate 

 sections or sub-genera ] but about fifty of the sixty-six are abso- 

 lute nonsense.* 



mon on the surface of the Ohio in summer, having the appearance of pieces of ropes 

 or oakum. It smells like Conferva.^' Rafinesque, I. c. p. 16. 



*^ Thus, Tomostigma is founded upon Draba Caroliniana; Hartiana, upon Anem- 

 one Caroliniana, &c. ; Stylisma, on Convolvulus tenellus, is said not to belong to 

 the Convolvulacem ; Helepta, with three species, is made from Heliopsis laevis ; En- 

 dodia and Jlplexia are founded, one on Leersia lenticularis, the other on L. Virgin- 

 ica; three genera are founded upon genuine species of Croton, and one on Stillin- 

 gia sylvatica, &c. &c. It is but fair to notice, however, that it appears from the 

 species cited, that his Ptilcmnium is the same with Discopleura, DC, his Spermo- 

 lepis with Leptocaulis, JVutt., and his Oxypolis with Archemora, DC, but mixed 

 with an Angelica and Tiedmannia. None of them could have been identified by 

 the characters assigned.
