EuMEX ELONGATUS X OBTusiPOLius. — A tall-growing narrow- 

 leaved Dock attracted my attention, last year, along the river- wall 

 between Putney and Barnes, Surrey. When I was able to collect 

 examples, in late July, it was mostly past flower and fruit. There 

 was something pecuUar-looking about the specimens that led me 

 to think that I had here a B. Hydrolapathum hybrid, but further 

 study inclined me to the belief that the characters I at first 

 ascribed to the influence of B. Hydrolapathum were really derived 

 from B. elongatus Guss. The Eev. E. F. Linton, who has recently 

 seen my specimens, agrees with me as to the hybrid being 

 B. elongatus x obtiisifoUus. Whilst the related hybrid B. crispus 

 X obtusifolius is of common occurrence, I do not think the 

 subject of this note has before been found in this country. 

 B. elongatus still grows by the Thames near Putney, where it was 

 noted many years ago, and also higher up the river between Mort- 

 lake and Kew. — C. E. Beitton. 



A CoREECTiON. — Canon Lett states in his notice of Mr. Mac- 

 vicar's " Distribution of Hepaticse in Scotland " (p. 37) that the 

 volume lacks an index. As such index is a very obvious feature 

 of the work in question, it is difficult to understand how anyone 

 who had even glanced through it could have referred to its 

 absence. — C. E. Lartee.

Though published by a London firm, this book is printed in 

 America, and the author is Professor of Botany in the University 

 of Kansas. None the less it is a text-book which should be 

 useful to teachers and students of botany in this country, as the 

 subject is treated in a manner somewhat different from the
