248 NOTES ON CAREX. 



says '• Lappouia, Laestadius in herb. Horn.," aud though Drejer, 

 Boott, and Bailey all say " vulijaris section," yet he places it in the 

 waritiince ; Lauge, Consp. t'l. Gioen. 145 (1885), puts Iti/perborea 

 next rir/ida under "Folia latiora plana ^IiZ/zfc/^e Lang (notLange)." 



In ^Tnnis. Ghisgow Xat. Hist. Sue. 110 (1888), Mr. P. Ewing 

 described a new British Carcx, " C. spiralis Ewing," from near the 

 ridge between Forfar and Aberdeenshire. This is one of the 

 ri(jid(£, and one of his specimens might well have supplied the 

 drawing of ('. hi/perburca in Anderss. Cyp. Scim. t. 5, f. 47 (right 

 hand fig.). I have not seen it mentioned in any of our Floras that 

 Dr. Boott has in his herbarium referred to " C. vuh/aris Fr. var. 

 limula (lii/pcrborea)," a specimen "from the Menai Bridge, Mr. 

 Bowman." 



C. AQUATiLis Wahl. in Act. Holm. 165 (1803). The lowland 

 specimens placed under this vary considerably; perhaps the nearest 

 to the majority of Wahlenberg's aquatiUs are those from Kerry and 

 the Thurso river, Caithness, while those from Ivirkcudbright have 

 much the aspect of some salina forms. The Ft. Danica plate 2477 

 (C. stans Drejer) might almost have been drawn from some of my 

 bcotch specimens, with the exception of the " spica mascula 1 " of 

 Drejer's description. Boott, Bailey, aud Hjelt all call stans an 

 aquatilis form. Nyman does not admit it for Europe, but Hjelt in 

 Fl. Fennica, 2G9, says, " In ora septentrionale Lapponia; ex Almquist 

 domiuatur, etiam in interiore parti obveuit." But almost all 

 manner of forms occur, some nearly connecting the mountain 

 forms ; and if we accept the thinner spiked lowland plants as fairly 

 representing Wahlenberg's original specimens (and they match 

 some of them very closely), then the stouter spiked forms not 

 attenuated below may retain the name of var., or forma of elatiur 

 Bab. = Watsoni Syme. The var. ciispidata has much the aspect of 

 some of the forms of C. hahpliila Nyl., which, according to Hjelt, 

 is C. aquatilis X saliiia * ciispidata ; aud he remarks that a specimen 

 from " Kantalaks," Herb. Norm. fas. 12, No. 85, under the name of 

 aquatilis citsjiidata, is " C. haluphila aj/inis," by this meaning the 

 subsp. ajfiins. Out of the British lowland plants some six or seven 

 forms might be evolved. 



Kemarking on specimens of the lowland form sent to the Ex. 

 Club in 1876, Dr. Boswell said: "This seems really the type of 

 the species." From the fact that Wahlenberg says " stepe aititu- 

 dinum humanum attingens," it was doubted whether our mountain 

 form could be the same. The late Dr. Buchanan White sent me 

 ail interesting form from the White Myre of Methven ; this Dr. 

 Almquist referred to '^ C. aquatilis var. epi<jejos ! ha^est." I have 

 never succeeded in seeing a type of Laestadius's plant, but I have 

 not doubted the name until 1 saw the account of this in Hjelt's 

 Fl. Fennica. There it is considered to be C. aquatilis x rii/ida, and 

 Dr. Almquist says the genuine plant is so. If this is so, I hardly 

 see how such a plant could occur in a lowland Perth marsh. If I 

 had to suggest a hybrid origin for Dr. White's plant, I should say 

 C. aquatilis X Goodenowii juncella, but Hjelt says that specimens 

 named C. arcuata Laest. [Bid. Kann. i. Tvrnea Lapp. 43 (i860)) in
