Flora ImjHca, oder aufzahlung nnd Beschreibung der Bliitlien- 



pflanzen und Gefass-Cryptogamen des Gouvernements St. 



Petersburg. Bearbeitet imd herausgegeben vou I^arl Fr. 



Meinshausen. St. Petersburg, 1878. (8vo., pp. 512.) 



This is a handy Httle descriptive Flora of the Province of 



St. Petersburg (lugermanland), written entirely in German. The 



author, who is Curator of the herbarium at the Academy of 



Sciences, has already greatly contributed to our knowledge of the 



district by his excellent series of exsiccata, 'Herbarium Florae 



Ingricae,' published in ten Centuries, fi'om 1860 to 1874 ; 



references to these are given throughout the present volume. 



The species are arranged in the usual Candollean sequence, 

 and amount to eight hundred and fifty-two Phanerogams and 

 twenty-nine Ferns and allies, not a larger flora than that of many 

 small English counties. The species are mainly the universal 

 ones of the great European plain, but there is a strong admixture 

 of more specially eastern types and a few local species ; the high 

 northern vegetation is very sparingly represented. Marsh, bog, 

 and tm-f-moss plants form a large proportion of the flora. The 

 district (which is almost entirely to the south of the city of 

 St. Petersburg) is divided by the author into four botanical zones, 

 and the species are traced through each. H. T. 



An appreciative notice, from the pen of Dr. Asa Gray, of the 

 venerable American botanist Dr. Jacob Bigelow, whose death we 

 announced at p. 96, is printed in ' Silliman's Jom-nal ' for April. 

 He had reached the age of ninety-two. 



M. Marchal, in the * Bulletin de I'Academie royale de Belgique,' 

 (ser. 2, xlvii.. No. 1), gives descriptions of eighteen new 

 species of Hederacem from Tropical Ameiica, taken from speci- 

 mens in the various European herbaria consulted in the 

 preparation of a revision of the whole of the extra-Brazilian 

 American species which he has undertaken. A new genus from 

 Brazil is described, — Coemansia, — dedicated to Eugene Coemans, 

 the well-kno^vn Belgian cryptogamist. It is allied to Aralia, but 

 differs in having 8-merous flowers and in other respects.
