 Var. LiLACiNA, Buch. White, Sf'ott. Nat. (1889) 299. A form with 

 pinkish petals occurs with the type and is not uncommon about 

 Basildon. In some alder gullies near Aldermaston a form or variety 

 occurs, which is analogous to the var. umbrosa of C. /lexuosa, and to 

 which it bears considerable resemblance. It has larger leaves than 

 the type, and the margins are much more angled, while the leaf is of 

 much thinner texture : it may be distinguished as the form or var. 

 umbrosa. I have not seen in Britain the hairy variety — var. Uirta, 

 Wimm. et Grab. Fl. Siles. ii. 265 — which is not unfrequent on the con- 

 tinent, and is figured in Flora Banica, t. 148, for C. hirsuta, L. 

 Cardamine amara is found in all the bordering counties.

 The common and widely distributed plant in Berkshire is not the 

 true Linnean Cardamine pratensis as restricted by Prof. A. Kerner von 

 Marilaun in the Schedae ad Floram Exsicc. Austro-Hungar, iii. (1884) 73, 

 but is var. palustkis (Peterm., in Rabenh. Bot. Centralb, i. (1846) 47, 

 as a species), w^hich is figured in Sm. E. B. t. 776, and reprinted in 

 Syme, E. B. t. 109. This is a plant with pinnate radical leaves, with 

 three pairs of distinctly stalked cordate leaflets, and usually lilac 

 flowers. Petermann's plant is of more frequent occurrence in western 

 and southern Europe than the genuine C. pratensis, but occurs with 

 it here and there. The true C. pratensis, which is figured in 

 the Flora Danica, fasc. xvii. t. 1039 (^79o)> ^^s radical leaves with
