 Stromness, Mainland, in " Journ. Bot.," vol. xxxix, August 

 1901, p. 267. 



Reseda lutea, Linn. — Gravelly ground round filter beds, 

 Kirkwall Waterworks Reservoir, near Hatston, Saint Ola, 

 Mainland, 31st August 1916, H. H. Johnston. Not native. 

 One plant only seen by me. 



Cerastium subtetrandrum, Mtirbeck (fide Arthur 

 Bennett). — Turf on igneous rocks, 10 feet above sea-level, 

 Black Holm, near Copinsay, 22nd August 1916, H. H. 

 Johnston. Native. Common. Sepals 4 or 5, petals 4 or 

 5, and capsule slightly curved or nearly straight, with 8-10 

 teeth, in the same plant. With reference to my specimens 

 of this plant, Mr Arthur Bennett, in a note dated 7th 

 November 1919, writes: "Not tetrandrum — sepals acute 

 and capsule nearly straight ; or it might be pentandrum, 

 a variety of triviale, but I think not. The length of the 

 capsule will not do for tetrandruvi. It seems to me to 

 agree fairly well with Lindman's figure of C. subtetran- 

 drum, Murbeck, = C jpumilwin, Curt., var. s. Lange." A 

 new record for this species for H. C. Watson's county 

 No. Ill Orkney. 



Sagina apetala, Ard. {fide Arthur Bennett). — Natural 

 turfy pasture at seashore, 10 feet above sea-level, Ayre 

 Loch, Copinsay, 22nd August 1916, H. H. Johnston. 

 Native. [I have a specimen of Sagina maritima, Don 

 {fide Arthur Bennett), collected by me at the same station 

 and on the same date.] Confirms the record of this 

 species for H. C. Watson's county No. Ill Orkney, by 

 Mr Patrick Neill in his "Tour," p. 185 (1806). 



Claytonia siberica, Linn, (name confirmed by Arthur 

 Bennett). — Roadside, 150 feet above sea-level, Binscarth, 

 Firth, Mainland, 6th September 1919, H. H. Johnston. 

 Not native. Escape from Binscarth plantation of trees. 



Ononis arvensis, Linn. [ = 0. repens, Linn.] {fide 

 Arthur Bennett). — Roadside, 25 feet above sea-level, Skaill, 

 Sand wick. Mainland, 6th August 1919, H. H. Johnston. 

 Not native. Rare. Petals pink. On visiting Skaill on 

 27th September 1919 I found no fruit on the growing 

 plants. See " Annals Scot. Nat. Hist," No. 26, April 1898, 

 p. 105; and "Trans. Bot. Soc. Edin.," vol. xxvii, p. 55 (1916).
