32 ANNALS OF SCOTTISH NATURAL HISTORY 



Aberdeen ; Boat of Garten, Inverness ; Findhorn, Elgin ; 

 S;mds of Barry and near Arbroath, Forfar ; and Arthur's 

 Seat, Edinburgh ; and I have seen specimens named by 

 Dr. Domin in the National Herbarium from Invercauld, A. 

 Croall ; Orkneys, E. S. Marshall ; Isle of Man, G. Holt. 

 Dr. Domin says that this plant is highly critical, its 

 systematic position causing great difficulty on account ol 

 the great variability of most of the examples. It often 

 vividly recalls K. albescens, but otherwise by a series of forms 

 is united with gracilis, as is well shown in my series on 

 shingle from Lydd in Kent. It is not impossible that it 

 frequently appears as a hybrid gracilis x albescens. 



K. GRACILIS, Pers., " Syn." i. 97 (1805;, is probably the 

 more frequent English plant. Dr. Domin diagnoses it as 

 follows: " Dense caespitosa, vaginis vetustis indivisis pallidis, 

 glauca (praecipue format glabrescentes saepe conspicue glauco- 

 virescentes), humilis vel elata, culmis gracilibus pro more 

 etiam sub panicula glabris, foliis saepe brevioribus rigidius- 

 culis, vaginis molliter pilosis rarissime glabris, laminis 

 angustis saepe convolutis vix plus 2 mm. latis ssepe in facie 

 pubescentibus, ligulis brevibus saepe exauriculatis, panicula 

 rarissime dense cylindrica saepius inferne subdilatata interrup- 

 taque pallida nitenti, ramis ramulisque tenuibus spiculis 

 angustioribus lanceolatis bifloris minutis solum 3-5 mm. 

 longis." At present I have no Scottish record for this, but 

 it is widely distributed in England, especially on calcareous 

 soil in the southern midlands. 



We have also in England K. gracilis, \z.?.gypsacea, Domin, 

 which I gathered on Durdham Downs, Gloster, W., in 1879 

 (hitherto known only from Nordhausen in Germany), and 

 var. latifolia, Domin, from Surrey, the latter a broad-leaved 

 hydrophytic form. 



Dr. Domin confirms the naming of my Uphill plant 

 K. vallesiana, Aschers and Graebn ( K. splendcns, Druce, in 

 "Journ. Bot," Nov. 1905, not of Presl.) and also of A", albescens, 

 DC., which I gathered on the Ouenvais in Jersey in 1877. 



Dr. Domin also describes 



K. GLAUCA, DC. "Hort. Monsp." i 16(1813). Sub-species 

 K. intermedia, Ahlquist, " Fl. Tunsten," 7 (1815) non Guss.,
