the Pacific. It has been received in our country with very great 

 interest, as many of the species are famihar to our lichenologists. 

 Tlie record even for Minnesota, however, must surely be far from 

 complete ; OjJegrapha is represented by only two species, the large 

 genus Lecidea by twenty-nine. There must be much work still 

 for field students. 



The plates illustrating the work are reproduced from photo- 

 graphs, but, though good in themselves, they generally miss just 

 the specific points that are necessary for purposes of identifica- 

 tion ; as illustrations of the text they are not without value. Mr. 

 Bruce Fink has earned the gratitude of lichenologists by this fine 

 contribution to a somewhat neglected branch of botanical study. 



Dr. Schellenberg's volume, containing a complete record of the 

 Smuts of Switzerland, forms part of a larger cryptogamic flora. 

 The preface gives a historic sketch of the study, the distribution 

 and natural history of this group of fungi, all of them parasites, 

 and some of them causing widespread diseases of cereals. They 

 are divided into two families, Ustilaginacea and Tilletiacece, ; keys 

 are given to the genera. With each species there is published an 

 account of infection experiments, germination of spores, &c., and 

 copious figures are provided of infected plants, spores, and germi- 

 nation stages. A list of host-plants, a bibliography, and a good 

 index complete a very full and interesting account of these 

 smut fungi. A T ^ 



BOOKNOTES, NEWS, dc. 



The last issue (July 4) of the Journal of the Linnean Society 

 (Botany) contains a paper " On the Flora of the Falkland Islands," 

 by Mr. C. H. Wright ; an enumeration of Chinese Ferns, by Dr. 

 C. G. Matthew ; and a revision of the genus Actinidia, by Mr, 

 S. T. Dunn. The first is based on a collection made by Mr. 

 Vallentin ; there are a few prefatory remarks, from which we 

 learn that the Tussac Grass {Poa flaheUata) is being rapidly 

 exterminated through the ravages of cattle, and that Primula 

 viagellanica, since the introduction of sheep, has decreased in 

 height and in the size of its flowers. 



Mr. Nathaniel Colgan contributes to vol. xxxi. of the Proceed- 

 ings of the Boyal Irish Academy a paper on the Gaelic Plant and 

 Animal-Names, and the folklore associated with them, of Clare 

 Island. They were collected from the country folk and fishermen 

 of the island in 1909 and 1910, none being admitted which have not 

 been obtained " in the field." The list is prefaced by an interesting 

 essay on various points connected with the names and their origin. 



Going about the Country ivith your Eyes open, by Owen Jones 

 and Marcus Woodward (Pearson, Is. net), is a volume of the 

 " Scout Library" and is mainly concerned with matters connected 

 with " Scout " life and with animals of sorts. There is however a 

 useful chapter on " How to know the Trees," and a practical one 

 on " Some Uses of the Hazel and Ash."
