 August 1919, H. H. Johnston; artificial pasture, 20 feet 

 above sea-level, Point of Onston, near the Bridge of Waith, 

 Stenness, Mainland, 3rd August 1920, H. H. Johnston ; 

 grassy and heathery pasture, 10 feet above sea-level. 

 Point of Onston, Stenness, Mainland, 9th August 1920, 

 H. H. Johnston : natural grassy and heathery pasture, 

 30 feet above sea-level, Deepdale, Stromness, Mainland, 

 14th August 1920, H. H. Johnston; and natural 

 heathery and grassy pasture, 40 feet above sea-level, 

 Purtabreck, North Ronaldsay, 20th August 1920, H. H. 

 Johnston. Native and common at all these stations. The 

 flowering season of this species in Orkney lasts from June 

 to August, the earliest and latest dates of flowering 

 observed by me being 6th June 1921 and 15th August 

 1919, respectively. The flowers are in greatest profusion 

 during July, while in August the plants are mostly in ripe 

 fruit Mr. C E. Salmon is of opinion that my specimens 

 from Scatter, Point of Onston, and Deepdale, are only 

 " small examples of R. stenophyllus, Schur.," and he has 

 not identified any of them as R. RuSTlCULUS, Sterneck, 

 although my specimens from the Point of Onston and 

 Deepdale were collected at the same stations as the plants 

 referred to by Dr. G. Claridge Druce in " Bot. Exch. Club 

 Secretary's Report for 1920," p. 140 (September 1921). 

 The stem of my smallest specimen from Deepdale is only 

 4 cm. (l^ inch) long, and the leaves are 8 5 mm. long 

 and 1 mm. broad. Rhinanthus stenophyllus, Schur., is 

 more common in Orkney than R. Crista-galli, Linn. 

 [ = R. MINOR, Bhrh.] (fide C. E. Salmon), of which I have 

 specimens only from grassy cliffs at the seashore, 40 feet 

 above sea-level, collected by me at Scapa, Saint Ola, Main- 

 land, on 5th July 1912. This latter species is also native, 

 and it was in flower and unripe fruit on 5th July 1912, 

 with green bracts, and a yellow corolla, with the two lateral 

 lobes of the upper lip small, short, roundish, and dark 

 purple in colour. See " Journ. Bot.," vol. xxxix, p. 270 

 (August 1901), and vol. xli, p. 295 (1903); "Bot. Exch. 

 Club Report for 1903," p. 7 (April 1904) ; and " Trans. Bot. 

 Soc. lildin.," vol. xxvii, p. 5G (19 IG).
