low shrubs, none of which were in flower or fruit. In the 

 Rev. Dr. George Barry's " The History of the Orkney Islands," 

 p. 280 (1805), the Elder is recorded as growing " on rills in 

 Hoy," where it still grows on the banks of Kirk Burn, near 

 The Bu, but, as this species only grows in Orkney where it 

 has been planted by man, it has no claim to be included in 

 the flora of the county.] 



The aggregate species Taraxacum officinale, Wiggers, 

 is recorded from Orkney in Watson, " Top. Bot.," ed. ii, 

 p. 236 (1883), but the following five segregate species are not 

 mentioned in that book : — 



Taraxacum bellulum, Dahlstedt {fide Hugo Dahlstedt). — 

 Grassy banks at seashore, 5 feet above sea-level, Sweyn 

 Holm, H. H. Johnston. Native. Rare. Plants sparingly 

 in flower, and growing in an uninhabited and uncultivated 

 island, used for grazing sheep on in summer. Dr. Hugo 

 Dahlstedt informs me that this species also grows in Western 

 Norway.
