26 REVIEWS. 



This half volume (Pars XIII., sectio posterior) has ap- 

 peared very nearly at the date announced for it, last autumn, 

 when the twelfth was published. It is the second part, antici- 

 pating the first, which is to contain the Solanacem and the 

 JPlantaginacece, two families which will finish the Monopet- 

 alous series, as this begins the Apetahu or Monochlamydece. 

 It comprises the Phytolaccacece, Salsolaceai (Chenopodeai), 

 Basellacecv, and Amarantacece, elaborated by Moquin-Tandon 

 of Toulouse, and the Nyctaginacem, by Professor Choisy of 

 Geneva. Of JPhytolaceacece we have in the United States, 

 only Petivera alliacca, which grows in Florida (probably not 

 in " Carolina"), liivma Icevis (to which we are surprised to 

 see M. portulaco'ides, Nutt., joined), and Phytolacca de- 

 candra, which last is now so widely dispersed over the world 

 that its native country is uncertain. 



The large family of Saholacece comprises 72 genera, dis- 

 posed nearly as in Tandon's " Chenopodearum Enumeratio," in 

 two suborders and seven tribes, most of which are further di- 

 vided into subtribes. Our genera of the Cyclolobeai (those 

 with the embryo nearly annular) are Aphanisma, Nutt., a 

 Calif ornian plant discovered by Mr. Nuttall ; Teloxys aristata, 

 which is credited to us because Linnaeus referred his Cheno- 

 podium Virginicum to C. aristatum, but it is doubtful if we 

 possess the genus ; Cycloloma (Salsola platyphylla, Michx.) ; 

 Chenopodium, to which Tandon now reunites the greater part 

 of his Ambrina (C. ambrosiodes, C. < in t hclminticum, etc.), 

 leaving in Roubieva only the original species, recently illus- 

 trated in this Journal by Mr. Carey ; Blitum, to which the 

 author now refers, as a section, his former genus, Agathophy- 

 ton (Chenopodium Bonus Henricus,Jj.^) ; Monolepis, Schrad. 

 (Blitum chenopod hides, Nutt.) ; Atriplex, of which too many 

 of the older species are credited to the United States ; Obione, 

 Gsertn., of which nine species are North American, including 

 (apparently with sufficient reason) the Pterochiton, Torr., 

 Grayia, Hook, and Arn., of a single species ; Eurotia ; a 

 doubtful Kochia ; a Corispermum (which Tandon seems not 

 to know as also a native of this country) ; Salicornia,in which 

 we have S. herbacea ? S. Peruviana (Caro. Eraser), and S.
