Haughwood, Capler Hill, Woolhope, Herefordshire. Speci- 
men and observations from Mr. Sracxnouss. Pe 
"This, and its varieties, have very generally been supposed 
by the English botanists to be the dg. piperatus. Linn.—who 
led them into the error, by quoting Haller and Bauhine for 
synonyms to his piperatus ; synonyms which undoubtedly belong 
to the ag Ns described by Dr. Lister, but by no means accord- 
ing with the Swedish plant. To avoid perpetuating this con- 
fusion, I have rejected the trivial name pipferatus; though 
applied. to it by J. Bauhine, who seems first to have givena 
description of it. F, B. bist. iii. p. 825. cap. 6. Dr. Lister 
seems first to have found it in England. His description, partly 
copied from J. Bauhine, may be found in Ray cat. p. 123, and 
also in Ray hist. p. 88.¢. 9. The-doctor observes that the juice 
1s mostly x tg out by the external: parts of the plant, that ee 
did not ige the surface of polished steel, that it became ~ 
when dried, but still retaining its acrid biting quality. 
e observed too that the plant was much eaten by insects and 
snails, Ray Sym, 4. 14.
