and 31 orders, over half arc now extinct, while others nre only found in South America, the 

 orient or the antipodes. — -The largesl alliances are Ranalee with 26 species, Rosales with 15 

 species, Sapindalcs with 15 species, Coniferales with 1 1 species and Urticales with 8 species. 

 One hundred and twenty-three are dicotyledons, only 10 of winch belong to t he gamopetalous 

 division. Among the conifers are Sequoia, Dammar a, Protodammara and Widdringtonites. 

 Figures show leaves of Devalquea, Manihotites and 4 Bauhinias. — L. Page. 



1599. Berry, Edward W. Eucalyptus never present in North America. Science 49: 

 91-92. Jan., 1919. — The author believes that the identification of Eucalyptus in many fossil 

 floras has led to erroneous conclusions in the minds of many geologists and botanists. The 

 theory of origin and distribution for the family Myrtaceae, advanced by him a few years 

 ago, considered America as the center of radiation for the family, and regarded the subfamily 

 Myrtoideae as the most ancient. The subfamily Leptospermoidcae was regarded as derived 

 from the former, and Axistralian types which are the peculiar ones of the family, were regarded 

 as having originated in that region in response to local environmental conditions subsequent 

 to the cretaceous radiation of the family stock. Genera such as Eugenia and Myrcia were 

 regarded as representing this ancestral stock more nearly than any other of the existing 

 genera. Eucalyptus was considered as one of the more specialized genera. The author doea 

 not regard the genus Eucalyptus as ever having been present in fossil forms in North America. 

 He advocates the dropping altogether of the use of Eucalyptus for the numerous North Ameri- 

 can Cretaceous forms, and the taking up of the genus Myrtophyllum and using it for leaves of 

 Myrtaceae whose generic relations cannot be determined with certainty, and more especially 

 for the leaves commonly referred to the genus Eucalyptus. — A. H. Chivers.

 Mississippi, Alabama and Georgia. U. S. Geol. Surv. Prof. Paper 112. 178 p., S3 pis. It 

 fig. 1919. — A monographic account of the geology and fossil floras of the earliest Upper 

 Cretaceous sediments of the eastern shores of the Mississippi embayment. The oldest for- 

 mation recognized, namely the Tuscaloosa, contains 151 species of plants, referred to genera 

 of which 50 per cent are extinct at the present time. Of special interest are the Conifero- 

 phyta represented by the genera Pinus, Dammar a, Sequoia, Androvettia, Protophyllocladua, 

 Brachyphyllum, Protodammara, Geinitzia, Abietites and Widdringtonites. There are 123 

 species of Dicotyls in the flora, 107 of these are Choripetalae and 16 Gamopetalae. New 

 species are described in Sphaerites, Lycopodites, Cladophlebis, Piperites, Ficus, Platanus, 

 Cocculus, Menisper mites, Capparites, Cassia, Leguminosites, Celastrophyllum, Sapindus, 

 Grewiopsis, Oreodaphne, Malapoenna, Conocoarpites, Aralia, Sapotacites, Calycites, Car- 

 polithus and Phyllites. — Overlying the Tuscaloosa formation are marine beds referred to the 

 Eutaw formation and correlated with the Turonian stage of Europe. These have furnished 

 41 species of plants of which the commonest is a well marked species of Araucaria. Still 

 younger beds are referred to the Ripley formation which is correlated with the Emscherian 

 stage of Europe. These beds have furnished 21 species of plants. The book is profusely 

 illustrated and contains complete tables of distribution. — E. W. Berry.

 of the Matoniaceae. Bull. Torrey Bot. Club 46: 285-294. Fig. 2, pi. 12, 13. 1919.— Fully 

 describes and illustrates a species of Matonidium from the Cretaceous of southwestern Colo- 

 rado. The second part of the paper discusses the former cosmopolitanism of the Matoniaceae 

 and plots the known occurrences of both existing and fossil species on a world map. — E. W.

 1919. — General account of the history and present status of the science. The various plant 

 phylae are discussed, the so-called vascular plants being segregated into the following great 

 groups: Pteridophyta (restricted to the Filicales) : Arthrophyta, comprising the modern 

 Equisetales and the extinct Sphenophyllae and Calamariae: Lepidophyta, comprising the 

 orders Lepododendrales, Lycopodiales, Iscetales and Psilotales: Pteridospermophyta or
