pflanzen mit kurzer V'egetationsdauer. Die Schutzstoffe sind meist 

 peripher angeordnet (bei Alkaloiden, Gerbstoffen z.B.); manche tre- 

 ten auch da rasch und leicht in Tätigkeit (Milchsaft, Raphidenschläu 

 che). Es scheint, dass wirklich die natürliche Auslese im Kampfe 

 ums Dasein bei der Entwicklung geschützter Pflanzen eine grosse 

 Rolle spielt, eine Auslese, die sich nicht in letzter Linie auf die 

 Güte der Waffen gegen die tierischen Feinde gründet. Für alle 

 Fälle gültige Formeln aufzustellen, geht aber nach Goebel vorläufig 

 nicht an. Matouschek (Wien).

 (Am. Journ. Sei. (IV). XXXVII. p. 57—60. taf. 1. 1914.) 



Records the discovery of the nuts of a fossil species of Nipa- 

 palm, Nipaditis Burtini urnhonatus ßowerbank in the lower Eocene 

 (Wilcox group) near Grenada, Mississippi. It is the first and only 

 known occurrence of this genus in the western hemisphere.

This paper is an abstract of a part of a monograph on the 

 Tuscaloosa flora of the eastern Gulf region in course of publication 

 by the U. S. Geological Survey. The plant bearing outcrops which 

 are in Alabama and Mississippi are enumerated with lists of 

 species occurring at each. In all over 150 species in 87 genera, 48 

 families and 31 Orders are enumerated of which upwards of fifty 

 are new to science. These are referred to the genera Aralia, Call- 

 cites, Capparites, CarpoUthus, Cassia. Celastrophyllum, Cladophlebis, 

 Cocculus, Conocarpites, Eorhamnidium, Equisetum, Eugenia, Ficus, 

 Grewiopsis, Hymenaea, J ungerrnannites , Legutninosites, Lycopodites, 

 Malapoenna, Me)iisper)tiites, Myrica, Oreodaphne, Persooina, Phylli- 

 tes, Piperites, Platanus, Populites, Proteoides, Sapindiis, Sapotacites 

 and Sphaerites. 



About 40 per cent of the whole number of genera are not re- 

 presented in existing floras and none of the Tuscaloosa species 

 survive into the Eocene. The flora as a whole is shown to be a 

 coastal flora with many Strand t3^pes. It indicates a land surface of 

 rather uniform topographj^ an abundant and well distributed rain- 

 fall, and an equable temperature of warm temperate or sub-tropical 

 type. Berry.

 Club. XLI. p. 295—300. 1914.) 



A preliminary abstract of a memoir on the Upper Cretaceous 

 floras of Maryland in course of publication b}^ the Maryland Geo- 

 logical Survey. Twenty-one species are listed from the Raritan 

 formation which is of Cenomanien age; one hundred species are 

 listed from the Magothy formation which is of Turonien age; and 

 a Single species is listed from the Matawan formation, also of 

 Turonien age. Berr5^
