quite regularly corymbose, instead of being of different 

 heights as in hyssopifolia; its leaves too are more uniformly 

 three-ribbed. 



In G. acris the leaves are pretty uniformly one-ribbed, 

 and the inflorescence much smaller and more contracted. 



All the species of this genus are well adapted for borders 

 of shrubberies, and for places where shade-loving plants 

 alone will grow.
