The plants included here have always passed as Boerhaavias, but 

 they differ widely from the plants of that genus in the habit of the 

 plant, form of the fruit, and shape of the perianth. Boerhaavia scandens 

 and several related species were included by Doctor Heimerl in the 

 section Adeyiophorae of the genus Boerhaavia.

The plant of this proposed genus have been variously placed in 

 Mirabilis, Quamoclidion, and Oxybaphus. to all of which the genus is 

 closely related. But besides differing considerably from all those genera 

 in general appearance. Hesperonia is separated from Ällionia and Mira- 

 bilis by the form of the fruit, differs decidedly from Mirabilis and Quamo- 

 clidion in the shape of the perianth, and is separated at once from 

 Quamoclidion by the number of flowers in the involucre.
