Several specimens of this hitherto undescribed species have 

 been lying in the herbarium of Columbia University for mam 

 years. The species apparently belongs to that class of plan s 

 which is peculiar to the Gulf States. It can be distinguished from 

 Aquilegia Canadensis at a glance by its more slender habit, pa e 

 green or glaucescent foliage and especially by the narrow elongate 

 sepals. The spur is more abruptly narrowed below the mi 

 than it is in Aquilegia Canadensis. 



The following specimens are referred here :
