This is a general treatise of systematic botan}' relating to the 

 Spermatophytes. It is a completely rewrittcn new edition of the 

 author's well know Systematic Botany as far as the Flowering Plants 

 are concerned. In the preface it is told us that the Cryptogams will 

 appear within this year as a separate book and with Dr. L. Kol- 

 derup Rosenvinge as author. The present treatise has a copious 

 phylogenetic introduction in which the author uses the discoveries 

 of late years in fossil botany and the many new investigations in 

 the Pteridophytes to build up the transition from the cryptogams 

 to the phanerogams. 



The System of the Gymnosperms adopted by the author 

 runs, as follows: 



Gymnospermae, Cycadinae (Cycadaceae, Zamiaceae), Ginkgoinae 

 (Ginkgoaceae), Coniferae {Taxales, Pinales, Cupressales), Gnetinae 

 (Ephedraceae , Welwitschiaceae , Gnelaceae). 



With regard to the Angiosperms the author mainly followed 

 the same arrangement as in his Systematic Botany, thus keeping 

 Monocotyledons separated from Dicotyledons. 



The orders of Monocotyledons are : Helobiales, Glumales, 

 (including also Juncaceae), Pandanales, Palmales, Arales, Enantio- 

 blastae, Liliales, Orchidales, Scitaminales. 



The Dicotyledons are divided into Choripetalae and Sympe- 

 talae, each subclass containing a number of orders.
