PLANTS OF NORTH SCOTLAND 267 



Fumaria panidiflora Jord. 111.- Abundant in cornfields near 

 the head of Loch Stenness, between Stromness and Sandwick ; 

 also east of Loch Kirbister. — F. Bnrm Jord. 108.- Cultivated 

 land at Dun Varrich, Tongue. 111. Oatfield near Scapa Bay, 

 plentiful.— F. murah's Sonder. 111.- Cornfields above Loch Sten- 

 ,ness, with F. paUidifiora ; in considerable quantity, but small and 

 apparently not quite typical. 



Barbarea arcuata Reiclib. 109.^'^ Frequent, and I believe native, 

 by the Wick Kiver, two to five miles above the town. Confirmed by 

 Mr. Bennett, who considers it practically identical with Thuringian 

 specimens collected by Haussknecht. B. vnlf/arU R. Br. grows just 

 above the bridge at Thurso, but has every appearance of being an 

 introduced plant. 



Arabis petraa Lam. var. Mspida DC. 108. Very scarce on the 

 north-west cliff's of Ben Hope, at about 2000 ft. I failed to find 

 Draba rupestris; perhaps a small state of D. incana may have been 

 mistaken for it there, as was the case in its reputed Irish station. 



Cardamine hirsiita L. 107. At 1500 ft. on Ben Griam More— an 

 unusual height for it to attain, according to my experience. 



Erophila prcBcox DC. {E. brachycarpa Jord. !|. 109.- Frequent 

 at Dunnet Links, and on the grassy cliffs hard by ; this greatly ex- 

 tends its known range in Britain. — E. infiata Hooker fil. ? 108.- 

 Pebbly drive at Loch Loyal Lodge, half-way between Tongue and 

 Altnaharra. Pods decidedly turgid ; very like what I have under 

 this name from Glen Shee, though (owing to the altered conditions) 

 much more robust. 



Cochharia groenlandica L. 108. Strand at Hielam Ferry; sandy 

 coast, Skerray. 111.- Exposed turfy headlands. Black Crai^, Main- 

 land. 



Viola silvestris Reichb. 109.- Bank near Bilbster Station.— 

 V. arvensis x tricolor. 111. Cornfields between Stromness and 

 Sandwick. 



Silene acaulis L. 106.- Ben Wyvis at 3000 ft., scarce. 



Lychnh alba x dioica. 108. t Near Tongue Ferry, with the 

 parents; confirmed by Mr. Bennett, who gives the following 

 synonyms : — Melamlri/wn diibium, Hampe, M. intermedium Schui° 

 17. album x rnbrmii Gaertner. Probably ''new" in name only ; 

 for, in a recent paper on the subject of natural hybrids, Mr. R. a! 

 Rolfe suggested that it was likely to prove not "uncommon. My 

 specimens were just intermediate in character, and appeared to be 

 sterile, but they were hardly advanced enough to make sure of this. 



Cerastiwn tetrandrum Curt. 108. A remarkable form (or state) 

 grows in fissures of the limestone clifi:'s filled with blown sand, three 

 or four miles east of Durness ; it is erect, with the inflorescence 

 mostly termmal, and approaches the C. alshioides Pers. of Southern 

 Europe. — G. semidecandrum L. 108.- Tongue, apparently very 

 scarce and local. 



Sarjina maritima Don, var. debilis (Jord.). 108. Scullomie Har- 

 bour. 



Lepiyonum rubnim Fr. 107. Plentiful on railway-ballast south 

 of Forsinard. — L. marlnum Wahl. 108.- Kyle of Tongue, local.
