CLASS V. ORDER n.l ULMUS. 431 



Habitat. — Sandy or gravelly soil ; rare. About the Lizard Pointi 

 Cornwall, — Rev. J. S. Tozer. Near Nesviuarket. — Rev. Mr. Hensted. 

 Perennial ; flowering from June to August. 



We have sought in vain for some prominent characters between the 

 plants distinguished as H. glabra and klrsuta ; in every particular we 

 find them the same, except in that of hairiness ; but this is of so very 

 variable a character as not to be constant in either one or the other. 

 It is true we have plants, both natives, and from the Continent, some 

 of which are quite smooth, and the others with the stem, leaves, and 

 calyx hairy ; but we have also numerous specimens in every inter- 

 mediate stage between the two states, so as to leave it doubtful to 

 which species they belong; and after having watched with care the 

 plants in difi'erent situations in Portugal, where they grow abun- 

 dantly, we cannot longer think they are other than varieties of one 

 species. It is a very different plant from the H. incana, Lain., which 

 is very hairy, with oblong lanceolate leaves, and about three, not 

 ten, flowers in a whorl, and it differs from H. alpina, VilL, which has 

 ovate-oblong leaves, ciliated on the margin, and about one flower in 

 the axis of the upper leaves, and the calyx is hairy. 



Rupture-wort was formerly supposed to possess the power of reducing 

 hernia ; but happily for us in our times so dangerous a malady is not 

 left to the supposed eflicacy of any plant. The whole herb is in- 

 odorous aud insipid.
