and more slender spikelets, between any of these three and our 

 ordinary C. aquatilis, which grows plentifully in the marsh at the 

 head of Loch Dochart, below Ben More; nor any approach what- 

 ever to the Forfarshire C. rigida var. inferalpina Laest., which 

 was, I think, originally identified by Mr. Arthur Bennett, and 

 has been confirmed by Kiikenthal. Mr. Bennett remarked on No. 

 3472 : — " I am glad to see this; I had not seen a specimen before. 

 As I expected, simply a reduced form" [i.e. of C. aquatilis]. I 

 may remark in passing that there is usually, if not always, a 

 considerable gap between the Scottish lowland stations of C. aqua- 

 tilis and the alpine ones; this species being quite absent from the 

 intermediate tracts. I know nothing of C. rigida vax. liviula; but 

 I believe that Kiikenthal considers C. limula Fr. to be a hybrid 

 between G. Goodenowii and G. rigida. By an unaccountable 

 error Mr. Dixon's name has been substituted for Mr. Druce's on 

 p. 196. — Edward S. Marshall.

 We transcribe the above from the wrapper of the work before 

 us, as it gives more information than appears upon the title-page. 

 So many changes have been made during the last few years in 

 what used to he a modest record bearing exclusively on plants 

 submitted by members that we are prepared for almost any deve- 

 lopment which may suggest itself to Mr. Druce, the indefatigable 

 "Treasurer and Secretary"; yet it comes to us with a certain 

 shock of surprise that even the title which has obtained for so 

 many years has been changed, and that the Botanical Exchange 

 Club has become also a " Society of the British Isles " ! We look 

 in vain in its pages for information as to this Society. Something 

 of the sort was proposed, we think, some time back by Mr. Druce, 

 but we were not aware that it had taken shape, and one feels a 

 natural curiosity as to its origin and organization, for even the 

 most energetic of men can hardly create a " society " by his ov/n 

 unaided efforts. A society usually possesses officers, and if we 

 assume, as we reasonably may, that Mr. Druce's connection with 

 the Exchange Club entitles him to be considered the Secretary 

 and Treasurer of the newly developed body, it would appear that 

 it is still acephalous if not amorphous. Mr. Druce seems to be 

 the only person who can tell us more, and, as the matter is 

 naturally of interest to British botanists in general, we are a little 

 surprised tliat, amid the wealth of information which appears in 

 the Report, no reference is made to the new departure. It would 

 seem moreover from a note, which we think is by Mr. Druce, on
