slender, narrow-leaved plant, growing in a pool near Lochan-nan- 

 Eoin, is called by Herr Kiikenthal var. recta (Fleischer), which 

 appears to be the same as var. recta Aschers. & Graebn. ; but 

 we cannot see how it differs from var. juncella. He names a 

 black-spiked plant from the banks of the Clunie, Braemar, u forma 

 fuliginosa R. Br. = C. melana Wimm. ,, -~*#. Goodenowii X rigida. 

 92. Lochnagar, in two places, with C. helvola ; also with C. rari- 

 flora Sm. (remarkably fine) in a swamp, at 2800 ft., descending to 

 the Dhu Loch. Determined by Herr Kiikenthal, who writes that 

 Dreyer's C. infuscata is merely a narrow-leaved, dark-spiked form 



of C. rigida.

HYBRIDS AMONG BRITISH PHANEROGAMS. 



By the Rev. E. F. Linton, M.A. 



(Concluded from p. 27G.) 



Polygonace*;. — Polygonum. Mr. Marshall reminds me of 

 P. minus x Persicaria and P. mite x Persicaria (B. E. C. Rpt. 



1892, p. 384), the latter ll teste Lange," and probably the former 

 also, collected by Mr. Druce from Abingdon, Berks, September, 

 1892. I have many specimens of hybrids from Germany, &c, but 

 have not detected any in Britain. The P. vrinus X Persicaria 

 which I issued from a gathering at Wareham, September, 1891 

 (/i. R\ C. Bpt. 1891, 343), I proved to be P. minus ; so elongate in 

 the wild state that Mr. Ar. Bennett thought it a variety. My speci- 

 mens of Continental hybrids show great sterility. Dr. Focke says 

 on P. minus x Persicaria, "very floriferous, but sterile or very 

 slightly fertile." 



Rumex conglomeratus X maritimus, Worthing, Sussex ; " seems 

 to be fairly fertile," Dr. Focke. Rev. A. Ley's Hoarwithy plant is, 

 I think, rightly named R. conglomeratus x sanguineus (li. Ruhmeri 

 Haussknecht). R. conglomeratus x obtusifolius I gathered at Witley 

 many years ago, and think that the R. st/lvestris Wallr. from Kew 

 riverside, though I have only a poor specimen, is this same hybrid ; 

 my specimens from Witley were rather sterile. R. conqlomeratus x 

 pulcher {B. E. C. Rept. 1872-74, p. 34). R. conglomeratus X crhpus,
