2774 d. Glyceria distans Wahl., var. pulvinata Fries. 

 Wells, Norfolk, July 1908, F. Long in Wats. B. E. C. Hep., 1911- 

 1912, 367. This was described by Fries in the Mantissa ii., p. 11, 

 and as Prof. Hackel tells me, is a variety with short (1-3 inches) culms, 

 in tight sods, growing on sea-shores and advancing to the water more 

 than any other grass (as Fries says). The panicle is small, contracted, 

 with short branches, of which the lowest are paired. The flowering 

 glumes are somewhat more acute. I have not seen the Norfolk 

 specimens, and Hackel says it is rare in Scandinavia, and occurs in 

 Russian Lapland, but is sometimes mistaken for var. capillacea. 



2817. Bromus japonicus Thunb., var. b. velutinus Asch. & 

 Graebn. Fl. Mittel-Europ. Alien. Galashiels, Selkirk, 1913, Miss 

 Ida M. Hay ward. 



2817 ter. Bromus marginatus Nees. Alien, South America. 

 Galashiels, Selkirk, Miss Ida M. Hayward ; Leith 1911, J. Fraser. 



2850 (2). Hordeum violaceum Boiss. & Hohenack Diagn. Ser. 

 1, xiii., 70. Alien, Asia Minor. Galashiels, Selkirk, 1912, Miss Ida 

 M. Hayward. Det. A. Hackel. A most beautiful and striking 

 species. 



2887. Asplenium germanicum Weiss. Respecting this plant 

 the great authority on Pteridophytes, Dr Woynar, writes me in 1913. 

 " Perhaps I may succeed in correcting a quite erroneous apprehension 

 in the valuable List of British Plants " [where A. germanicum is 

 queried in synonymy as being a hybrid of Ruta-muraria and septen- 

 trionale]. " A. germanicum, even if a hybrid at all, cannot certainly 

 be A. Ruta-muraria x septentrionale. The anomalous texture of A. 

 germanicum cannot originate from an intermingling of Ruta-muraria 

 ' blood ' with the tender green of septentrionale. Moreover the chief 

 stations utterly preclude the combination. Proof positive against it 

 is the actually existing hybrid of Ruta-muraria and septejitrionale of 

 which a sun-print of a Tyrolean plant is annexed. Plants of this 

 [hybrid] found in Sweden and in Switzerland incline much more 

 towards A. Ruta-muraria, just as do the plants from the Vosges. In 

 my opinion it is clearly evident that this can be neither a form of 

 Ruta-muraria, germanicum nor of septentrional e." The only question 

 which arises on this note is, whether we have the true germanicum in
