CAITHNESS PLANTS 279 



the Fl. Scanica, p. 156 ; this occurs in the Nov. Fl. Suec. ed. 2, 

 p. 280 (1828), where Fries refers it to Persoon. Mr. Williams, 

 Prod. Fl. Brit, part 9 (1912), p. 509, makes this to be the 

 C. angustifolia Hoppe. Taschenb. iii. p. 160 (1792), but some 

 German authors refer it to G. vemalis Kuetz, and Hegelmaier, in 

 his Monograph (1864), p. 56, remarks, "perhaps the same as 

 C. vemalis" Koch, Syn. ed. iii. (1857), p. 212, places it under 

 C. hamulata Kuetz " G. angustifolia Hoppe, forma foliis omnibus 

 linearibus." As Hoppe's name dates from 1792, if the plant is 

 placed under intermedia as a variety it becomes C. intermedia 

 Hoffm. var. angustifolia (Hoppe). There is no doubt the plant 

 has a distinct look about it, but it is difficult to get absolute 

 characters, unless the " Styli et bractese caducse " against the 

 " Styli persistenti " of intermedia is to be so considered. But 

 C. angustifolia is so rarely found in flower, that it is difficult to 

 confirm or deny this. 



3. Utricularia vulgaris L. — In the Scottish Bot. Eev. 

 (1912), p. 181, I recorded the above species as "Probably not 

 characteristic." I had not seen specimens, and those submitted 

 to Dr. Trail I supposed were not sufficient to decide on. But on 

 p. 235 I was able to record it definitely, from specimens sent 

 by Miss and Mr. Lillie from Loch Watten, which is on the 

 eastern watershed of the county ; it also grows in Achkisloch (or 

 Stemster), which, although so near the east coast, belongs to the 

 north-west watershed. See also Ann. Scott. Nat. Hist. (1911) p. 47. 



4. Utricularia major Schmid. (U. neglecta Lehm.). — Loch, 

 Eangag (alt. 375 ft.), and Loch Stemster (alt. 469 ft.), Mr. G. 

 Little, sp. This is on record for E. and W. Eoss, and the Outer 

 Hebrides, and although the late Mr. Beeby had doubts (there 

 being no flowers), I quite think that specimens he sent me from a 

 " loch near Scalloway " will prove to be this rather than vulgaris, 

 though he did not agree to this. 



5. Ajuga pyramidalis L. — This species is far more widely dis- 

 persed over the country than was supposed. Mr. Crampton (op. 

 cit.) records it from several stations with rosy-pink, white, and blue 

 flowers, as "on talus below landslip at the Traigh Fhada (Long 

 Beach) one mile north of Babbae, Berriedale ; at Badsallock, north 

 of Berriedale, on gravel talus ; north bank of the Lang well Eiver." 

 The Eev. W. E. Linton also found it near Berriedale, and it occurs 

 in several places up the Thurso Eiver (Mr. Lindsay) ; this year 

 Mr. Lillie has found it near Lybster. I have a specimen gathered 

 by Mr. E. Heddle (10 June, 1847) at Dunnet. There are culti- 

 vated specimens from Dickson's garden at Broad Green, Croydon, 

 "root from Ben Nevis," in the British Museum Herbarium. 



6. Potamogeton Sturrockii A. Benn. — Stemster Loch, July, 

 1913, Mr. Lillie. It grows here with P. alpinus, heterophyllus 

 pusillus, and Friesii. I now have this from co. 52. Anglesea, 

 86. Stirling, 89. Perth E., and 102. Ebudes S. It is rare in the 

 United States, and I have not yet seen European specimens other 

 than Scottish. Ascherson and Graebner, Syn. Fl. Mitt. Europ.
