sea-level, Galilee, North Loch, Lady, Sanday, 27th August 

 1920, H. H. Johnston. Not native. A weed of cultivation. 

 Rare. Calyx pale yellow. Central lobe of upper lip of 

 corolla dark purple ; two lateral lobes oblong, longer than 

 broad, yellow. Confirms the record of this species from 

 Orkney in "Annals Scot. Nat. Hist.," No. 30, p. 97 (April 

 1899); Bennett, "Suppl. Top. Bot.," ed. ii, p. 60 (1905), 

 where, Mr. Arthur Bennett, in a post-card dated ISth 

 February 1921, informs me, the refei'ence " Sc. Nat. 1883, 

 73 " is wrong, and it should read " Annals Scot. Nat. 

 Hist.," No. 30, p. 97 (April 1899); and Spence, "Flora 

 Orcadensis," p. 53 (1914).« 



Ajuga reptans, Linn, x pyramidalis, Linn, {fide G. C. 

 Druce and Arthur Bennett). — Dry heathery and grassy 

 hillside (burnt within the past few years) facing the south, 

 290 feet above sea-level, north side of Syradale, Firth, 

 Mainland, 20th May 1920, H. H. Johnston. Native. 

 Rare. Plants in full flower growing among typical Ajuga 

 PYRAMIDALIS, Linn., and in the same valley with Ajuga 

 REPTANS, Linn., which I collected near the same place 

 on 17th August 1883, and quarter of a mile distant on 

 6th September 1919. This hybrid resembles A. reptans, 

 Linn., in having stolons which are shorter than those 

 of that species, the leaves are subglabrous or have a few 

 short hairs on both surfaces and longer hairs on the 

 margins, the whorls of flowers are arranged in laxer 

 pyramidal spikes than those of A. pyramtdalls, Linn., 

 and the corolla is blue, with the middle lobe of the lower 

 lip slightly emarginate. In my specimens of A. pyra- 

 midalis, LAnn., collected at the same station, on 20th May 

 1920 and 29th July 1920, the leaves and bracts are very 

 hairy on both surfaces in most of the plants, but in 

 other plants they are only moderately hairy on both 

 surfaces. Mr. Arthur Bennett informs me that the 

 above-mentioned hybrid is recorded in Foche, " Pflauzen 

 Mischlinge," p. 341 (1881), and in other European botanical 

 works. 



Scutellaria galericulata, Linn. — Artificial heap of 

 stones at seashore, 10 feet above sea-level, Sennes, Garsow 

 Wick, North Ronaldsay, 21st August 1920, H. H. Johnston. 

 Native. Rare. Plants in full flower. Corolla blue. C)n
