It is not easj^ to point out a mark of specific difference between 

 this and the preceding species, yet manj circumstances produce a 

 coaviction that they are really distinct. The H. patens grovs plen- 

 tifully in the driest pastures along the sea-coasty rarely exceedingtwo 

 inches iri^ hei^^ht, with its stem always dichotomous and expandin^^ 

 flowering in February and March. It is seldom seen after the first «f 

 April. When ponds occur in dry pastures it is sometimes fouDfloB 

 their margins, but without any chani>*p of halnt or annoarance. The 



H. ccerulea grows in bogs ancf swan_^. ^, 



ways slender and erect; it does not flower until May or June, and con- 

 tinues in bloom throuj^hout the summer. Its corolla is at least tlirec 

 times as large as that of the H patens, and tlie segments of its calji 

 and stem leaves proportionally more slender.
