nographia Generum Plantarum,' which was discontinued at the end 

 of the first volume. Two parts are out : " the cryptogamic plates are 

 very beautiful." 



Of Jaubert and Spach's * Illustrationes Plantarum Orientalium ' 

 eight livraisons are published. 



Lindenberg's ' Monographia Hepaticarum Generis Plagiochilae ' is 

 a work illustrative of a group of Jungermannise having for its type our 

 J. asplenioides. The hair-splitting system seems to have been carried 

 to a great length ; for the Editor observes that " the slightest change 

 in the fonn of the leaf, the presence or absence or size of a tooth, di- 

 rection of the foliage and of the branches, the presence or absence of 

 surculi, &c. &c., all and each are considered tokens of specific dis- 

 tinction, without taking into account the influence of soil, exposure 

 and climate ; " and by these means the number of species of Plagio- 

 chila is increased to ninety-six ! The work is however spoken of in 

 terms of praise for the beauty of its figures and the manner in which 

 the characters and descriptions are drawn up. 



The first volume of Grisebach's 'Spicilegium Florae Rumelicae et 

 Bithynicae ' is spoken of as " a most valuable addition to our know- 

 ledge of Eastern Botany." A letter fi-om the author explains the plan 

 and object of the work. 



The first volume of Ledebour's ' Flora Rossica ' is out and extends 

 to the end of the Legurainosae. 



A notice is given of the plates to the botanical part of the antarctic 

 expedition of the Astrolabe and the Zelee, in 1837 — 40, under Admi- 

 ral d'Urville. They are highly spoken of. 



Kiinze's ' Fairnkrauter ' is a supplement to Schkuhr's admirable 

 work bearing the same title. Six fasciculi are published, and con- 

 tain sixty coloured plates of new Ferns, or such as were not figured 

 by Schkuhr. Kiinze's ' Riedgraser ' is in like manner a supplement 

 to Schkuhr's work on the Carices. Three parts contain thirty plates, 

 with specific characters and descriptions. 



Mr. Bateman's ' Orchidaceae of Guatemala and Mexico,' and Dr. 

 Lindley's ' Sertum Orchidaceum,' are deservedly spoken of in terms 

 of high commendation. 



The first No. of Mr. Benthara's ' Botany of the Voyage of H. M. S. 

 Sulphur,' has just appeared : it contains ten plates of new species, 

 from drawings on stone by Miss Drake. It " extends as far as Paro- 

 nychiaceae of the Californian plants ; " and six quarterly parts will 

 probably complete the Botany.
