VIOLA TRICOLOR VAR. SABULOSA AND ALLIED FORMS 345 



Among the specimens of var. sabidosa in Herb. Kew. which I 

 refei- to f. discolor are : — (1) on dunes of the island of Walcheren, 

 Holland, near the farm Oranjezon, adjoining the village of Oost- 

 Kapelle, 18i9 {Gaij, in company with Dr. Bosch), (2j on the dunes 

 of Dunkerque, France {A. Boreau, 1854 ; S. V. Vercier, 1855,— 

 recorded as in flower April 18, and fruit formed August 26), (3) on 

 the dunes of Staples, arrondissement of Montreuil-sur-mer, de- 

 partment of Pas-de-Calais (T. de Clermont, 1853). To f. concolor 

 I refer a specimen in Herb. Kew. (ex herb. Arthur Bennett) from 

 the dunes of St. Quentin-en-Tourment, department of Somme 

 {E. Gonse, 1877). 



Of the three varieties of grex maritima, we have therefore : — 

 (1) var. sabidosa, under two forms, extending from Memel, on the 

 extreme north-east coast of Germany, westward to the north-west 

 coast of Spain, but not found on the British coasts. 



(2) var. Pesneaui, extending no further south than Delestages- 

 de-Coueron, in the department of Loire-Inferieure, but found also 

 on the British coasts ; where it was first recognized in a plant 

 from the islet of Mochras, near Harlech, Merioneth {E. G. Baker, 

 in Journ. Bot. 1901, p. 9). This is the particularly hairy plant 

 with all the petals blue-violet. 



(3) var. Gicrtisii, the yellow-flowered plant, apparently confined 

 to the British coasts, and not known on the Baltic and Atlantic 

 seaboard of the Continent. This was first described in Engl. 

 Bot. Sitppl. t. 2693 (June 1831), from a plant found at Braunton 

 Burrows, on the coast of Devon, where it was first gathered by 

 W. Curtis, and cultivated in his garden under the name of " Viola 

 littoralis." Whether Curtis was aware of Sprengel's plant of the 

 same name is very doubtful — the apt name for this sea-shore 

 violet being probably no more than coincidental. 



Probably some of the plants with " concolorous " petals found 

 along the coasts of Germany and Denmark should be referred to 

 var. Pesneaui, judging from Borbas's somewhat vague remarks 

 under V. tricolor in the last Gei'man edition of Koch's Synopsis, 

 p. 223 (1892). He says that in the maritime plant of the dunes, 

 the petals are (all) violet, the upper somewhat darker, and that 

 sometimes the plant is thickly covered with short, hispid hairs. 

 This could hardly apply to var. sabidosa i. concolor, which is quite 

 glabrous ; but it would fit the description of var. Pesneaui, as 

 clearly defined by Rouy & Foucaud, Fl. de France, iii. p. 50. The 

 stipules in var. Pesneaui are quite different in appearance from 

 what I have described in the two forms of var. sabidosa. And for 

 this, among other reasons, I would suggest the exclusion of the 

 latter from the British List. 



A small Viola collected by Miss C. E. Palmer, in 1900, in a 

 barren field outside Stoyn Wood, Bembridge, Isle of Wight, was 

 named by Borbas " Viola banatica Kit." It has, however, 

 nothing in common with tlio Transsilvauian plant, which is a 

 plant of mountainous districts. Tliis addition to the British List 

 will form the subject of a future note.
