ON VIOLA TRICOLOR var. SABULOSA Cand. 

 AND ALLIED FORMS. 



By Frederic N. Williams, F.L.S. 



During a recent stay at Knocke, on the Belgian coast, I had 

 the opportunity of studying this plant under various conditions of 

 growth. Its appearance in the British List dates from the first 

 annual report (1858) of the Botanical Exchange Club, p. 7, 

 published at Thirsk (in 1859), under the auspices of Mr. J, G. 

 Baker. It is there stated to have been found on the sandhills of 

 New Brighton, in Cheshire. It is also stated that these examples 

 of ''Viola sabulosa" have more hairy stems and leaves than 

 V. Ourtisii. This, however, condemns the plant at the outset ; as 

 var. sabulosa is a glabrous plant, and the form tliat has its stems 

 and leaves more hairy than the yellow-flowered V. Ourtisii is the 

 form we now know as- V. Ourtisii var. Pcsncaui, or more correctly 

 V. tricolor subsp. Ourtisii var. Pesneaui (see also E. G. Baker, in 

 Journ. Bot. 1901, p. 9). In his Fl. Oheshire, p. 39 (1899), Lord 

 do Tabley says that the place where the plant was found is now 

 built over, so that recent examples are not available for comparison.
