2. PINGUiCULA, Tourn. Butteuwort. (From pinguis, fat, in allu- 

 sion to tlie greasy-viscid surface of the leaves.) — Terrestrial acaulescent herbs, of 

 moist or wet ground (in northern hemisphere and the Andes) ; with fibrous roots, 

 broad and entire leaves in a rosulate radical tuft, their upper surface with a coat-

 under irritation ; scapes naked, 1-flowered, circinate-coiled in vernation. Upper 

 lip of the corolla 2- and lower 3-lobed or parted; the lobes .sometimes incised ; 

 the base anteriorly saccate, and the bottom of the sac contracted into a nectari- 

 ferous spur.

 or parted; luwer'S-iiarted ; lobes mostly quite entire : boreal species.

 vi. 568. P. acufijblia, Michx. Fl. i. 11, the crect-rosulate oval and very acute leaves described
