purplish and the corolla of a deeper color. Besides these more conspicuolia dif- 

 ferences, the corollas in A. greenei are noticeably longer, more arched, and wider 

 at the throat. These differences in color and size of corolla and calyx, and evident 

 differences in the calyx teeth, seem to be the most important diagnostic characters 

 in a group of closely related but distinct species, which, until recently, have been 

 taken to belong to two or three very variable ones. 



A character which is indescribable with our present vocabulary is to be found in 

 the peculiar odors of these plants, because of the volatile oils they contain. These 

 differ very perceptibly in the different species, some of them being pronounced.
