Of this g"enus, confined thus far to America, there is a 

 fourth species, J. albiila^ with white flowers, and bipinnati- 

 fid leaves, discovered by Dombey, near Lima in Peru. 



I have, in restoring this genus of Micliaux, altered his 

 name merely for the sake of euphony, but retained the al- 

 lusion, without ve^ituring to criticise its exceptionable 

 composition as formed in part from the name of the pre- 

 ceding genus, Ipoyncea, with the addition of o-^k;, as in- 

 dicative of their common resemblance, sufficiently apt 

 when we compare the /. coronopifolia with the Ipomcea 

 Quumoclit, deducting, indeed, the diversity of habit. That 

 Michaux's name has been independently derived from the 

 Greek, without any reference to Ipomcea^ and founded 

 upon its striking appearance, as supposed by the editor of 

 this article in Rees's Enc) clopccdia, seems altogether im- 

 probable. 



Nearly all the genera composing the Natural Order PO' 

 le:irmi(ki^, are peculiarly indigenous to America.
