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

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

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



4. P. Lusitanica, (Fig. 30.) pale Butterwort. Spur cylindrical, ob- 

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