Bibliography. 199^ 



Plants and Animals, 1835, is wrongly placed by De Candolle among 

 the yellow-flowered species of the second section. It has purple flowers 

 and should stand next TJ. purpurea. The name U. Greenei, Oakes, 

 in Hovey's Mag. must stand as a synonym ; as there is no good reason 

 for changing the prior name imposed by the discoverer. 



The order PrimulacecB is elaborated by M. Duby of Geneva ; who 

 follows Endlicher in the general distribution of the family. From some 

 inadvertance, Glaux maritima is not cited as an American plant. 

 Naumburgia thyrsiflora, Moench, = Lysimaclda thyrsiflora, Linn, and 

 L. capitata, Pursh. The L. revoluta, Nutt., is referred to L. longifolia, 

 Pursh. The common Samolus of the south western United States, which 

 has smaller flowers than the true S. Valerandi, is referred to S.Jlorihmdus, 

 H. B. K. S. ebracteatus, is not noticed as a plant of the United States, 

 although it is common along our southern borders ; nor is it distinguish- 

 ed even as a subgenus, although, on account of its nearly free ovary and 

 want of sterile filaments, a recent writer (M. Baudo, in A7in. Sci. Nat., 

 Dec. 1843,) has separated it, to form his genus Samodia. In the Myr- 

 sinacece, elaborated by the editor, we meet with two Noi'th American 

 species, both natives of Florida, viz. Myrsine Floridana, Alph. DC, 

 and Ardisia Pickeringia, Torr. & Gr. To the small order Theophrasfa- 

 cecB, Alph. DC., our author has joined Jacquinia, a West Indian genus, 

 one species of which extends into Florida. In the order Sapotacecs, the 

 editor has proposed one new North American species of Bumelia. In 

 EhenacecB, we have only our Persimmon. From this, the order Sty- 

 racece (embracing Symplocinece and Halesiacece of Don,) is distinguish- 

 ed chiefly by the position of the cells of the ovary opposite the lobes of 

 the calyx. Hopea is kept as a mere section of Symplocos ; including a 

 dozen Asiatic species as well as our S. tinctoria. 



The order OleacecE is published from the manuscripts of the late Prof. 

 De Candolle. The American species of Fraxinus still require the la- 

 bors of a monographer. 



The order Jasminecz is made to comprehend Bolivaria, (of which 

 there is at least one Texan species,) and Menodora ; and the family 

 BolivariacecE, is shown to have been founded upon misconceived char- 

 acters. 



For the elaboration of the Ajyocynacece, we are indebted to the younger 

 De Candolle. The only North American genera are Amsonia (is not 

 Echit.es Fraseri, Roem. and Schultes the A. ciliata, Walt. ?) Apocy- 

 num and Forsieronia, (F. dijformis, DC. ,^=Echites difformis, Walt.) 



The order AsclepiadecB has been very faithfully studied by De Caisne. 

 All the North American representatives belong to the tribe of True As- 

 clepiadecc, with the exception of Gonohius, of which we have several 

 Species, (one of them, collected by Dr. Short, forms the new G. tilicefo-
