224 RECENT ADDITIONS TO OUR MOSS FLORA. 



notice; and as Mr. J. G. Baker, who has kindly assisted me in com- 

 jiaring- with his set of Jordan's specimens, concurs wiih me in identify- 

 ing it with V. Pailloiixii, Jord., a brief note upon its occurrence may 

 be of interest. From true V. arvensls, as generally understood by 

 British botanists, it may at once be distinguished by the size of the 

 flowers, which are about \ in., sometimes more, across; while from 

 V. tricolor it differs in the colour of the blossoms, the lower petal 

 being yellow, the others usually cream-coloured, the two upper rarely 

 slightly tinged with blue. This is pre-eminently the cornfield Pansy 

 of the district, being abundant in cultivated ground, and especially 

 luxuriant in clover-fields. V. arvensh is not unfrequent, but V. tri- 

 color is rare, and uncertain in its appearance. Grenier and Godron 

 (Fl. de France, i. 183) unite V. PaiUouxii with V. Sagoti, Jord., as a 

 variety of V. tricolor, and describe it as having " Ses petales presque 

 aussi larges que longs, et dont Ics deux superieurs sout contigus par 

 leurs bords;" this is the case in the fresh specimens now before me. 

 V. Sagoti and V. Pailloiixii seem to be scarcely separable even as 

 forms; but it is with the latter, judging from Mr. Baker's specimens, 

 that the Buckinghamshire Pansy is the more closely connected. I 

 hope to collect specimens this summer for distribution through the 

 Exchange Club, and shall be glad then to learn the opinion of other 

 botanists upon the plant. — James Britten. 



Erysimum eepandum, L. — I found about half-a-dozen specimens 

 of this plant, a native of the South of Europe and the Orient, in a 

 grassy road between Acton and Turnham Green, in May last. — James 

 Britten.
