NOTES ON SOME BRITISH SEDGES. 77 



familiar with C. riglda in a living state will follow Prof. L. H. 

 Bailey in combining it with C. Goodenowii ; these frequently grow 

 together, and the intermediates may prove to be hybrids between 

 the two. Goodenough's types of rujida at Kew illustrate the normal 

 plant admirably. 



0. AQUATiLis Wahlenberg. Specimens from the moorland above 

 Corrie Kander (Glen Callater), S. Aberdeen, are placed by Herr 

 Kiikenthal as var. epigeios Andersson ; their glumes are very dark 

 brown. The plant distributed by Dr. Buchanan White under this 

 name from the White Myre of Methven, Perthshire, labelled 

 ''var. G. epigeios Laest. forma videtur sec. Almquist," he calls 

 " Carex vulgaris Fr. y elatior Lang, 2. angustifolia m." — it is 

 clearly a form of Goodenowii, and not of aquatilis. My Aberdeen- 

 shire examples closely approach a Finmark plant of Th. M. Fries, 

 labelled " var. epigeios Wahlb." 



0. aquatilis X rigida. Four gatherings are so named : — (1) From 

 the above-mentioned bog on Glas Maol ; (2) from the wet moorland 

 above the head of Glen Fiagh, Clova; (3) from near the Little 

 Culrannoch (with some doubt ; the specimens may be rigida, infer- 

 alpina) ; (4) from the Clach Leathad range, Kingshouse, Argyle- 

 shire. In the first three stations the supposed parents grow 

 together abundantly ; in the fourth I did not observe C. aquatilis, 

 but the sheet is, as my correspondent remarks, " C. aquatili propior 

 quam posteriori" [rigidc€:\. They all seem to be partially, if not 

 entirely, sterile. So far as I am aware, this hybrid was not pre- 

 viously recorded from Britain. 



C. GooDENown J. Gay. I received through the Botanical Ex- 

 change Club plants collected by Mr. J. E. Griffith near Holyhead 

 in 1889, labelled "(7. ehjtroides Fries. See J. of B. 4/89." Herr 

 Kiikenthal remarks : — ''Carex ehjtroides Fr. ex orig. longe aliena, 

 nempe hybrida Carex gracilis x vulgaris. Haec est nil nisi forma 

 elatior C. vulgaris." I believe that this opinion applies equally to a 

 similar plant of Mr. Griffith's from Maelog Lake, Anglesey, 6/93, sent 

 under the same title. British botanists call C. gracilis " C. acuta 

 L.," following Fries, &c. 



C. Goode7iowii X rigida. I forwarded a sheet from the Allt 

 Giubhas, near Kingshouse, Argyle (c. 2000 ft.), suggesting this 

 name, and received the following note upon it: — " Very probably 

 Carex rigida X vulgaris. The strong red-brown rhizome, the 

 broader leaves, with involute margins, and the black spikelets 

 point to G. rigida, while the laxer habit speaks for C. vulgaris." 

 I have very little doubt of this identification being right ; the 

 influence of rigida is unquestionable, but it is hardly pure rigida. 



C. PANicEA L. var. intermedia (Miegeville). There are specimens 

 at Kew of Bordere's gathering from near Gavarnie, Hautes-Pyre- 

 nees, at 1450 metres, collected in 1870 and 1875, and named as 

 C. intermedia Miegeville, which exactly match my Fort William 

 plant. " Hffic forma pulchra reducta Caricis panice^." — G. K. 

 He remarks that K. Eichter refers C. intermedia to vulgaris Fries, 

 as does Nyman ; but this appears to be an error.
