 M'Kay ; bogs of Aughterflow and Shannon, Ross-shire. 



Perennial ; flowering in June. 



This is a very pretty little delicate plant, and a very interesting addi- 

 tion to our list of British plants ; it appears to have been overlooked by 

 Sir J. E. Smith, as P. Lusitanica. 



4. P. Lusitan'ica, (Fig. 30.) pale Butterwort. Spur cylindrical, ob- 

 tuse, shorter than the nearly regular limb of the corolla, scape 

 hairy, as well as the leaves, which are thin and veiny, capsule 

 globose.

 tersected with numerous purple or reddish veins. Scape from three to

 small glands. Corolla pale purple, the throat yellow, beautifully 

 streaked with red. Spur light yellow.

 shire, Devonshire, and Cornwall. "Plentiful in the Hebrides and
