174 ENGLISH BOTANY. 



C. puUa and C. Grahami are perhaps only two varieties of one 

 species, but I have never gathered the latter : have only a single 

 specimen from each of its two known localities, and as these two 

 specimens are very different from any of the hundreds of specimens 

 of C. pulla which I have seen growing, I have treated them as 

 subspecies. Perhaps a larger series of specimens of C. Grahami 

 would fill up the gap between the two forms. C. pulla is smaller in 

 all its parts, and both the male and female spikes fewer than in 

 C. Grahami ; the bracts are broader and blunter, the fruit nmch 

 shorter and very much more abruptly acuminated into the beak, and the 

 beak is shorter. The colour of the female spikes, both of their glumes 

 and of their fruit, is darker. 



Dr. Boott in " Eng. Bot. Suppl.," though he does not describe the 

 nut of C. Grahami, appears to have found it perfect ; and Professor 

 Babington seems also acquainted with it. Were the nut abortive 

 there would be little doubt remaining of C. Grahami being a form of 

 C. pulla with the perigynia much enlarged and barren such as are 

 found in several species of Carex.

EXCLUDED SPECIES. 



ERIOPHORUM CAPITATUM. Host. 

 E. Scheuchzeri, Hoppe. Koch, Syn. Fl. Germ, et Holv. ed. ii. p. 60 ; et Auct. Plur. 



Said to have been found by Mr. George Don in 1810, "by the side 

 of a rivulet on Ben Lawers, near the limits of perpetual snow." As 

 there ai'e no " limits of perpetual snow" on Ben Lawers, or any other 

 Scotch mountain, the description does not tend to inspire confidence 

 in Mr. Don's accuracy, and throws doubt on the source of his speci- 

 mens, if he really distributed C. capitatum, as the late Dr. Walker 

 Amott seems to imply when he says, " we fear that Mi\ Don had 

 accidentally mixed some foreign or cultivated specimens with E. 

 vaginatum" (" Brit. Fl." ed. viii.). The figure in " English Botany," 

 ed. i. No. 2387, is certainly nothing more than E. vaginatunti, and the 

 only specimen of Don's supposed E. capitatum which I ever saw — 

 viz., that which was in the herbarium of the Botanical Society of 

 London — belonged without doubt to the same species. 



CAREX BRIZOIDES. Linn. 



Said to be gathered in Studley Wood, near Ripon, Yorkshire:
