We have only Hudson's authority for the growth of this plant '"^'^'~^ ^ 

 in Britain : '' Habitat in Wallia, Per. Aug., D. Haviland." It has "' " ^!^lL.' 

 never been reported since ; and may now, after a lapse of a hun- 

 dred years, be deemed extinct as a British plant, if it ever had 

 any claims to this rank. Kittel, in ' German Flora,' p. 650, in- 

 forms us that it grows here and there in woods and hedges, espe- 

 cially in the south of Germany.
