174 ANNALS OF SCOTTISH NATURAL HISTORY 



" mascula erecta lanceolata " need imply this, and the objection 

 would be equally valid against C. vesicaria, L., the only possible 

 alternative, which also has two to four male spikelets. 



Var. utriculata, Kiik. Plants from near Cong, West Galway 

 (No. 1478), and Lough Drin, Westmeath (No. 142 6), which seem 

 hardly separable from Mr. Lloyd-Praeger's supposed C. rhyncho- 

 physa, were named by Kiikenthal C. rostrata, var. latifolia, 

 Aschers (1864). An even stronger form, found by Mr. Shool- 

 bred and myself in Glen Clova (No. 2764), was identified by 

 Mr. Bennett with C. ampullacea, var. robusta, Sender (1851), 

 an earlier synonym of var. clatior, Blytt (1861). I suspect that 

 all the above-mentioned gatherings should rank as one variety, 

 which in Lond. Cat. I have called C. inflata, var. robusta. 



C. Grahami, Boott. A careful study of wild specimens from Clova, 

 as well as of living plants from that locus classicus, cultivated 

 at Kew and Bournemouth, has quite convinced me that this is 

 a variety or subspecies of C. vesicaria, L. The var. alpigena, 

 Fr., as named for me by Kiikenthal, has short, roundish female 

 spikelets and a shorter beak, and agrees well with some 

 specimens issued in Herb. Normals, Fr., though not quite with 

 all. This tends towards C. saxatilis, L. (pulla, Good.); 

 the transitions from which to Grahami, e.g. in the bog below^ 

 the neck separating Ben More from Stobinian (also called 

 Am Binnein and Ben Ein), are numerous, and may be due 

 in part to hybridity. When growing by itself, C. saxatilis is 

 very characteristic and quite constant ; I regard it as being 

 more distinct from vesicaria than is C. lepidocarpa from type- 

 flava.

ON SOME SCOTTISH ALPINE FORMS OF 



CAREX. 



By P. EWING, F.L.S. 



I HAVE been asked to put on record, through the medium of 

 the " Annals," my opinions regarding some of the critical 

 forms of our alpine Carices, and now that Georg Kiiken- 

 thal's able monograph of the genus has been published in the 

 " Pflanzenreich " the work is much simplified. His arrange- 

 ment, however much it may differ from the arrangement of 

 former authors, is the one I prefer to follow in whatever
