In the course of his paper the author has omitted varieties, except 

 where distinct enough from the types to describe them as species. The 

 most important changes are as follows: 



Aspleniiim dentigeriim Wall, has been placed as a „form" oi A. Filix- 

 femina Beruh, owing to its great Variation and the streng resemblances 

 betvveen the two species (the latter species is rare in N. W. India); 

 Aspidium aiiriculatiim has been broken up into four, the original species 

 never being found in N. India; the name ^. aciibatiimSw. {— „lobatiim" 

 of Continental botanists?) should be discarded and is in the author's 

 opinion not applicable to any Indian plant; none of the varieties of 

 Nephrodinm (Lastrea) Filix-mas have been united with the type but 

 some of the less divergent forms have been put under A^. parallelo- 

 grammum Kunze, Nephrodinm odontoloma (Moore) Bedd. (N. F. inas 

 var. 2 normalis C. B. Clarke) is believed to be the same N. pallidum 

 Bory of S. E. Europe and W. Asia; no connection is recognised bet- 

 ween A^. marginatum Wall, and N. elongatum H. and Gr. or any form 

 of A'^, Filix-mas ; Nephrodinm prolixnm Baker, which seems to have in- 

 cluded A'. ochthodes Kze. and A'. tylodes Kze., has been resolved into its 

 original constituents; the N. W. Himalayan plant, referred to these 

 latter species which always has a markedly creeping and branching rhi- 

 zome, has been separated as A^. repens n. sp.; the same character sepa- 

 rates Polypodium (Phegopteris) late-repens (Trotter) Hope from P. distnns 

 Don. — The summary is followed by a table of contents, a list of plates 

 and by a list of the ferns, described in the author's treatise.

 ecological surveying. (^New Phytologist. Vol. III. Oct. 

 1904. p. 200—204.) 



A vacation party spent two weeks examining the distribution and 

 habitat of maritime Vegetation on the northern coast ofBrittany at the 

 Bouche d'Erquy. The area is estuarine with Salicornia herbacea, 

 Glyceria maritima, Siiaedu fruticcsa, Obione portnlacoides, and Jiincus 

 maritimiis as dominant species, forming well-defined associations. Sur- 

 vey parties of three persons each, reduced the physical features and 

 plant associations to conveniently sized maps ; while other members did 

 earth-boring, levelling, estimation of salt in soll, photography, etc. The 

 details of Organisation and procedure will be useful ro others who under- 

 take similar survey. Smith (Leeds).

Ce travail est un extrait des recherches que l'auteur poursuit depuis 

 plus de 30 ans sur les Riibiis de la region angevine. 60 especes bien 

 distinctes y sont decrites ; plusieurs formes sont nouvelles. 50 hybrides, 

 dont l'origine n'est souvent que soupconnee, sont en outre enumeres.
