PLANTS OF NORTH SCOTLAND 273 



Spcm/animii s'uiiplex Huds. 111. Swampy ground near the South 

 Burn, Hoy, a mile or more from Rackwick. — S. affine Schnizl. was 

 flowering in a pool near Sandy Loch, towards Orgill. 



Potamogeton Jieteroplujllus Schreb. 111. A narrow -leaved plant 

 in the pool just mentioned ; Mr. Bennett remarked that it had the 

 look of P. (/racilis Wolfg. (non Fr. i, a heterophyllus-ton'n. found in the 

 lakes of Finland, &c. — P. heterophyllus x perfoliatus [ P. nitens 

 Weber). 111. Mill-pond between Stromness and Sandwick (form 

 P. curvifolius Hartm. ). Pool at the north-west end of Loch Kirbister 

 (form P. intermedins Tis.). With the parents. 



Zostera vwrina L. var. anguati folia Hornem. 108.'' Kyle of 

 Tongue, very local ; Mr. Bennett points out that Hornemann, not 

 Fries, was the author of the varietal name. 



Eleocharis uniglumis Reichb. 111. Plentiful on the south side 

 of Loch Stenness. E. multicanUs Sm. was noticed not far from 

 Rackwick, Hoy. 



PJriophoriwi latifoliuiH Hoppe. 108. Below Ben Loyal, on the 

 west side. 



Carex paucijiura Liglitf. 107. Plentiful at 500 ft. on the moor- 

 land between the railway and Ben Griam More. 108. West of Ben 

 Loyal, between 300 and 400 ft. I never saw it below 1000 ft. else- 

 where. — C. incurva Lightf. var. erecta 0. F. Lang {= C. j unci folia 

 All.). 108." Damp micaceous ground at Scullomie Harbour. 

 Stems erect or ascending, 2-12 in. long; leaves much longer than 

 usual, those from the root occasionally attaining a height of 6 in. 

 Mr. Bennett has it from Orkney ; I have gathered a very similar 

 form near the Matterhorn, above Zermatt. — C. chordorrhiza L. (in 

 Ehrhart, Phytophylacion). 108. This is abundant in a swamp on 

 the north side of the Mudal Water, Altnaharra, as well as on the 

 south side. — C. paniculata L. 111. A few plants in a swamp east 

 of Loch Kirbister. — C. carta Good. 108. Dried-up lake near Loch 

 Modsarie, between Tongue and Skerray ; also in the marshes near 

 Loch Naver, Altnaharra — -scarce in both stations. It seems to be 

 rare in the north. — C. aqnatilis Wahl. 109. The prevailing form 

 of the Wick River is ordinary low-ground aqiiatilis [elatior Bsih.); 

 but a plant occurs not uncommonly with decidedly acuminate or 

 cuspidate glumes, half as long again as usual. — C. aguatilis x 

 Goodenowii. 109. f Wick River, in two forms; one (a very beautiful 

 plant) rather approaching tToodenowii in its inflorescence when dry, 

 though looking exactly intermediate in a living state ; the other, of 

 which I seem to have gathered only one example, looks just between 

 the two. — C. aquatilis x salina, var. kattegatensis ( X C, Grantii 

 Ar. Benn.). 109. Three or four forms were collected ; one, which 

 approaches aquatilis, is probably the C. aquatilis var. cuspidata 

 Laestad., now considered to be a hybrid. The variableness of 

 C. salina hereabouts is very great. — 0. Goodenowii J. Gay. 108. 

 A curious form (or monstrosity) was found in good quantity by Mr. 

 Shoolbred at the south end of Loch Deerie ; it has small globose or 

 ovoid female spikelets, the solitary male spikelet bearing several 

 apparently perfect fruits at its apex. — C. pilulifera L. var. longe- 

 hracteata Lange \Leesii Ridley |. 106. Ben Wyvis. — C. panicea L.
