paper-making from the result of so small an experiment : I should 

 requii-e at least a ton (more would be better) to test it practically 

 and make pa^Der from it. It may be worth more than the value I 

 mention, but only a practical working trial into paper can properly 

 test this x^oint." The grass grows in the green f)arts of woods and 

 on moorlands all over Scotland [and England] , and could be culti- 

 vated where nothing else of any value will grow. As the plant is 

 perennial, the only expense after the first outlay would be that of 

 gathering in the crops. — A. Craig- Christie. 



Middlesex Plants. — Specimens of a large form of Carex divisa, 

 Huds., and oi Juncus Gerarcli, Lois., have been brought to me by 

 Dr. De Crespigny, who gathered them by a pond in Piatt's Lane, 

 Hampstead, this summer. Both of these species are not known 

 to grow elsewhere in the county, though the former was formerly 

 common in the Isle of Dogs. As both have usually decided tidal 

 or semi-maritime proclivities, their occurrence at Hampstead is 

 remarkable, and would x^erhaps, if followed out, be traceable to 

 transportation (either accidental or intentional) : this was probably 

 the case with the maritime Atriplex at Hampstead, recorded in 

 ' Journ. Bot.,' 1871, p. 33. — Henry Trimen. 



Barbarea stricta in Middlesex. — Mr. Baker (Journ. Bot. ix. 

 213) mentions the occurrence of this plant by the Thames at 

 Isleworth. I have found it this year in abundance at short 

 intervals along the Duke's River, between Twickenham and 

 Worton Lane. The different aspect of this plant from B. vulgaris 

 (which is here associated with it) is very remarkable, especially 

 when both are in a young state : this 'is partly attributable, as 

 Mr. Baker observes, to the deeper colour of the petals, and still 

 more to the yellow-green of the foliage. Dr. BosweU (' English 

 Botany,' i. 174) describes the foliage as " dark green," and the 

 petals as " paler yellow " than those of B. vulgaris; but in the 

 Isleworth plant the exact contrary is the case. — James Britten.

 That great desideratum, a Flora of Em-ope, is not likely to be 

 forthcoming at j)resent ; but as a precursor to it, and to a con- 

 siderable extent supplying its place. Dr. Nyman's new treatise will 

 be very welcome. It is more than twenty years since he published 

 his'SyUoge' (1854-55), an excellent book, which has proved its 

 usefulness in the hands of everybody working at the plants of 

 European countries, and served as the basis of arrangement for 

 most herbaria. In this interval very much has been published,
