ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 203 



historical account of travellers, collections and literature. In all, 105 

 genera and 633 species have been recorded from the islands ; the 

 Isoctales and the Matoniacese are at present unrepresented. To facilitate 

 research, a series of simple synopses of the genera is given. The 

 arrangement adopted approximates to that employed by Diels in Dk 

 Naturlichen Pflanzenfamilien. Suggestions are added as to the parts oi 

 the plants that should be collected, and as to the points that should be 

 noted in the field. 



American Ferns. — B. D. Gilbert* gives a list of 53 species and 

 12 varieties of ferns, and 23 species and 7 varieties of fern allies, that 

 occur in the State of New York ; and adds notes upon their distri- 

 bution and the geographical characteristics of the region. The flora i? 

 a large one, owing to the mingling of northern and southern types 

 W. N. Clute f publishes some Fernwort Notes. Nephrodvum molle being 

 reported as growing in Florida, he inquires whether it is really native, 

 and points out the characters by which it is distinguished from J\ r . patens. 

 He quotes four instances of exotic ferns which have become naturalised 

 in the States, and adds another record in Lygodium japonicum, which 

 seems to have escaped from a greenhouse in Georgia. He gives reasons 

 for regarding Nephrodvum spimdosum var. intermedium as a mere form 

 of a variable species. He quotes J. B. Flett's opinion that Lycopodium 

 Selago may be regarded as an alpine or arctic form of L. lucidulum, but 

 by no means as a xerophytic form. A. A. Eaton,! in publishing his 

 fifteenth paper on Equisetum, treats of the varieties of E. hiemale. He 

 describes in detail eleven varieties, three of which are new, and gives 

 their distribution. "W. N. Clute,§ having studied carefully the ternate 

 forms of Botrychium, gives his views about the classification of these 

 difficult and variable plants.
