 %-. — There appears to be no doubt that these supposed distinct species are no- 

 thing more than varieties. They grow indiscriminately, and the lobes of the 

 leaves assume almost every variety of form. The sepals are white, blue, or 

 pale purple. This plant has been much used as a remedy in pulmonary dis- 

 eases ; but its virtues have no doubt been overrated.
