154 NOTES ON HIGHLAND PLANTS* 



* Potamogeton natans L. Lochan below Stob Ban (97). — P. 

 polygoni folios Pour., var. angustifolius Fr. [fide Bennett). Lochan 

 Feoir, Assynt. 



Rhyncospora alba Vahl. The form gathered in Glen Nevis, near 

 Loch Awe, and near Inchnadamph, differs from that of Surrey and 

 the " landes *' of W. France in the colour and shape of the heads, 

 and answers to the description of var. sordida in Babington. 



^Carex carta Good., b. alpicola (Wahl.). W. side of Coniveall 

 (108), at over 2500 ft. — C. stricta Good. Specimens from Lochan 

 Feoir, Assynt, are referred to this by Dr. Lange. The fruit, how- 

 ever, appeared veinless, when fresh, nor were the reticulations of the 

 lower sheaths present ; and the plants, though densely tufted, 

 were not u tussocky." If correct, this would be a great northern 

 extension of its range, from Aberdeenshire. There are some Irish 

 specimens in Herb. Brit. Mus., S. Kensington, which are perhaps 

 the same, under the name of stricta. Mr. H. N. Ridley considers 

 it Goodenowii; but nothing in the large series of that species at S. 

 Kensington appears to me identical with it ; and I should at 

 present be somewhat disposed to doubt its belonging to either. — C. 

 rigida Good. Abundant on the E. side of Ben Klibreck (107). 

 Obs. Among the Carices gathered by Mr. Hanbury and myself in a 

 bog above the head of Canlochan Glen, Forfar, on July 23rd, 1886, 

 was a form of this, which Dr. Lange now names " var. infiiscata 

 Drej., vel C. hyperborea Drej., statu juniori." Mr. Arthur Bennett 

 tells me that it is not true hyperborea, though coming near it. He 

 has kindly sent me the following description . — M Car ex rigida Good. 

 /3. infuscata. Culmo erectiore, minus crasso, foliis angustioribus, 

 marginibus revolutis, acutioribus erectiusculis, spicis tenuoribus 

 laxioribus auriculisque bractearum infuscatis. C. saxatilis Wahlenb. 

 fl. lapp. p. 247, ex parte. Eng. Bot. 29, t. 2047 ! Faero ! Island 

 (specimina ambigua). Gronland ! Ex hac ut mihi videtur, deri- 

 vator forma spicis multo elongatioribus basi magis rarifloris, peri- 

 gyniis stramineo-viridibus, squamis obtusissimis perigynio minor- 

 ibus, fuscis, in Gronlandia baud rara et ad speciem sequentem [*. £• 

 No. 33 /3., p. 460] accedens." Drejer, in ■ Eevisio critica Caricium 

 borealium.'— *C. aquatilis Wahl., b. Watsoni Syme. By Mudal 

 Water, Altnaharra (108). Spikelets more slender than in my 

 Wick and Thurso specimens, and more like one from the river Isla, 

 E. Perth, labelled "var. virescens Anderss.' — C. glauca Murr., c. 

 stictocarpa (Sm.). Cliffs above Lochan-na-Lairige, at over 2000 ft. 

 + C. pelia F. O. Lang. 



Loch Naver, Altnaharra (108). Quite 



from Mr. Nicholson's Perthshire specimen (which he kindly lent me 

 to look at) so named by Dr. Christ ; the beak of which does not 

 accord with the following description, for which I have again to 

 thank Mr. Bennett, who also determined my plants, gathered m 

 very ripe fruit :— « 99. Carex pelia i*i****t i- e., Uvidus). Rhizomate 

 stolonifero, culmo acutangulo scabro, foliis carinatis planis latis 

 rigidis margine scaberrimis, spica mascula solitaria, foemineis 1-8 

 elonj?ato-lanceolatis laxifloris pedunculatis erectis, fructibus oblongo- 

 ovatis enerviis glabris rostro brevi integerrimo* Hab. in pal. 



In a heathy bog, not far from the head of 

 a (108). Quite a different-looking plant
