NOTES ON SOME BRITISH SEDGES. 75 



F. Sclmltz (C. loliacea Sclik., non L.), C. divulsa Good, (and forma 

 C. guestphalica F. Scb., Bonning. as a species), and C. Duricci 

 F. Sch. [G. virens auct. nonuul., C. divulsa /3 virens Darieu). What 

 C. virens Lam. was cannot be ascertained, and the existing specimen 

 derived from Lamarck is in such bad condition that notiiing can 

 be seen in it to afford any means of deciding" (p. 455). 



"The C. muricata Hoppe (non Koch, nee auctorum), i.e. 

 C. canescens Leers (non Lin.), wliich grows near Weissenburg and 

 near Neustadt, sometimes together with the everywhere common 

 0. contigua Hoppe [0. muricata Koch et auctorum), and which is 

 so different from it that a non-botanist who helped me to collect it 

 never once confused them, I have named C. Leersii, because I am 

 now convinced that Linne understood both under the name 0. mu- 

 ricata. According to the researches and drawings of my friend 

 M. Paira, as well as my own observations, it differs from C. contigua 

 Hoppe i7iter alia by the glume, which is much broader than long (in 

 C. contigua it is much longer than broad), by the lowest bract, 

 which is linear-lanceolate (in contigua it is ovate), by the shorter, 

 broadly ovate perigynia, narrowed into a short beak (in C. contigua 

 they are longer, and narrowed into a longer beak), and by the nut 

 being sessile on the base of the perigynium (in C. contigua it is 

 placed far above the base). 



" I have found C. Leersii in various places on the slopes of the 

 Haardtgebirge towards the Rhine valley, e. g. in great abundance in 

 woods on the Rothliegende and on the borders of the Vosges near 

 Neustadt, on the borders of vineyards near Weissenburg. 



" The closeness or remoteness of the spikelets affords no con- 

 stant character ; for I have found 0. contigua on Madeburg, in the 

 Palatinate, with spikelets quite as distant as in C. Leersii and 

 C. divulsa. I have called these C. contigua var. remota" (p. 459). 



I find the above distinctions to hold good in the var. 2-)seudo- 

 divulsa of Surrey and Kent. This has the glumes mostly about 

 half the length of the fruit, taken together ivith its beak, i. e. falling 

 considerably short of the fruit alone; in our ^'tyi^e-muricata" 

 (= (7. contigua) they are about as long as the fruit without its beak. 

 In var. pseudo- divulsa the fruit is considerably smaller than in 

 C. contigua Whether it should rank as a species or as a variety 

 must remain for the present an open question, so far as I am 

 concerned. 



C. ECHiNATA Murray, var. grypus (Schkuhr). My gathering of 

 this, from the AUt Giubhas, near Kingshouse, Argyleshire, was 

 assented to by Mr. Arthur Bennett, and agrees well with the figure 

 in Hoppe's Caricologia Germanica. The roots which I took home 

 in 1888 changed, however, into normal echinata the following 

 year; Dr. Buchanan White also informed me that he did not 

 think much of the Perthshire grypus. " Carex grypus Schk. nil 

 nisi forma alpina obscurius colorata subreducta Caricis echinatas."
