Ferns, especially the Filmy Ferns of Jamaica. By Rev. 

 David Paul, LL.D. {Trans. Bot. Soc. Ed'ui. vol. xxii. pt. 1, 1901). — 

 The author compares the area of Jamaica to that of Inverness-shire, 

 and also the number of genera and species of Ferns in the whole British 

 Islands, viz., 20 genera and 47 species, with the 45 genera and 473 

 species found in Jamaica. Thereafter his remarks are confined to the 

 Filmy Ferns, of which Hymenopliyllum has 23, and Trichomanes 25 

 species in the island. He recognises the difficulty of transporting 

 healthy and vigorous plants for cultivation in this country, and affirms 

 that " anyone who loves Ferns, and has means and leisure, would find 

 that a holiday spent in these islands (Jamaica, Grenada, and St. 

 Vincent) would repay him a thousandfold in the interest and pleasure 

 he would experience at the time, and in a store of delightful recollections 

 which would be a cherished possession to him all the days of his life."
