V. BRUNELLA. 109 



sions, by the form of the calyx, (five-fold or two-fold), 

 and then went into the wildest confusion in distinction 

 of species, sometimes by the form of corolla, sometimes 

 bv that of calyx, sometimes by that of the filaments, 

 sometimes by that of the stigma, and sometimes by that 

 of the seed. As, for instance, thyme is to be identified 

 by the calyx having hairs in its throat, dead nettle by 

 having bristles in its mouth, lion's tail by having bones 

 in its anthers (antherae punctis osseis adspersae), and 

 teucrium by having its upper lip cut in two ! 



14. St. Hilaire, in 1805, divides again into four sec- 

 tions, but as three of these depend on form of corolla, 

 and the fourth on abortion of stamens, the reader may 

 conclude practically, that logical division of the family 

 is impossible, and that all he can do, or that there is the 

 smallest occasion for his doing, is first to understand the 

 typical structure thoroughly, and then to know a certain 

 number of forms accurately, grouping the others round 

 them at convenient distances ; and, finally, to attach to 

 their known forms such simple names as may be utter- 

 able by children, and memorable by old people, with 

 more ease and benefit than, the ' Galeopsis Eu-te-trahit,' 

 ' Lamium Galeobdalon,' or ' Scutellaria Galericulata,' and 

 the like, of modern botany. But to do this rightly, I 

 must review and amplify some of my former classifica- 

 tion, which it will be advisable to do in a separate 

 chapter.
