SHORT NOTES. 



Glyceria Foucaudh Hackel in Hampshire. — I have come across 

 a sheet, labelled u Glyceria maritima Wahl. Saltmarsh near Mude- 

 ford, S. Hants. 15, vi. 1893," and collected by Rev. E. F. Linton, 

 who added the remark: — " Large, but I suppose ordinary ?" It 

 agrees, I consider, very well with specimens of my No. 867, from a 

 muddy ditch on the coast near Grain, West Kent, June 21st, 1892, 

 on which Professor Hackel wrote to Mr. Arthur Bennett in 1893 as 

 follows: — " Glyceria Foucaudii, Hackel in litt. ad Foucaud (n. sp.). 

 This is a very distinct species of Glyceria, discovered last year 

 by Foucaud in the Department of Charente-Inferieure. Foucaud 

 himself will soon publish a description of it. It seems to be one 

 of the Atlantic plants which reach southern England. You may 

 distinguish it from all the congeners (it comes nearest G. maritima) 

 by the silky pubescence of the nerves of the flowering glumes, and 

 by the ciliated upper palea, &c." I understood that Hackel had 

 altered his opinion as to its specific rank, and it was accordingly 

 mentioned in the Flora of Kent (p. 405) only as a remarkably luxu- 

 riant form of G. maritima. But in September, 1904, he named an 

 identical grass, found that summer by Miss M. C. Knowles on 

 Auginish Island, Foynes, Co. Limerick, as " typical Atropis Foil- 

 caudii Hack, in Husnot, Gramina, p. 49 (1896)/' It certainly looks 

 like a good species, when well developed. — Edward S. Marshall. 



British Bubi. — As is well known to my friend Dr. Gilbert, 

 and as indeed he has plainly shown in his " Notes on British 

 Bubi M in the April number of this Journal, — there is the widest 

 disagreement between him and me on this subject. But the dis- 

 agreement is so wide, and, in a sense, so fundamental, that I cannot 

 think any useful purpose would be served by a detailed discussion 

 of his views in the pages of the Journal. If such views as to vari- 

 ability of form and frequency of crossing between allied forms are 

 accepted, all serious study of the genus might well be given up as 

 hopeless and unprofitable ; but most of us who have given time 

 and patient work to the study are not in the slightest degree pre- 

 pared for such a surrender, and the various vague conjectures and

* Mr. Baker writes, "not glanduloso-setose'*; but all the specimens I have 

 seen from the classical station have a few sessile or subsessile glands on the 

 petiole.
