II. PINGUICULA. 49 



The Butterworts are a perfectly distinct group 

 whether small or large, always recognizable at a glance. 

 Their proper Latin name will be Pinguicnla, (plural 

 Pinguiculse,) their English, Bog- Violet, or, more fa- 

 miliarly, Butter wort; and their French, as at present, 

 Grassette. 



in itself, but variously supported and confirmed by the two following, 

 to K. J. Mann, Esq., M.D., long ago a pupil of Dr. Linclley's, and 

 now on the council of Whitelands College, Chelsea: for the second, 

 to Mr. Thomas Moore, F.L.S., the kind Keeper of the Botanic Gar- 

 den at Chelsea; for the third, which will be farther on useful to us, 

 to Miss Kemm, the botanical lecturer at Whitelands. 



(1) There is no explanation of Lentibulariacese in Lindley's ' Vege- 

 table Kingdom.' He was not great in that line. The term is, how- 

 ever, taken from Lenticula, the lentil, in allusion to the lentil-shaped 

 air-bladders of the typical genus Utricularia. 



The change of the c into b may possibly have been made only 

 from some euphonic fancy of the contriver of the name, who, I 

 think, was Rich. 



But I somewhat incline myself to think that the tibia, a pipe or 

 flute, may have had something to do with it. The tibia may possibly 

 have been diminished into a little pipe by a stretch of licence, and 

 have become tibula: [but tibulus is a kind of pine tree in Pliny]; 

 when Len tibula would be the lens or lentil-shaped pipe or bladder. 

 I give you this only for what it is worth. The lenticula, as a deriva- 

 tion, is reliable and has authority. 



Lenticula, a lentil, a freckly eruption; Zenttcularis, lentil-shaped; 

 so the nat. ord. ought to be (if this be right) lenticulariacecs.

 Lentibularia is an old generic name of Tournefort's, which has 



been superseded by utricularia, but, oddly enough, has been retained
