Of this genus, confiT\ed thus far to America, there is a 

 fourth species, /. albida, with white flowers, and bipinnati- 

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



I have, in restoring- this g-enus of Michaux, altered his 

 name merely for the sake ofeuphony, but retained the al- 

 lusion, without venturing to criticise its exceptionable 

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

 ceding- g-enus, Tpomoca, v.^ith the addition of o-^t^^ as in- 

 dicative of their common resemblance, sufficiently apt 

 when we compare the /. coronopifoUa with the Ipomcea 

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

 Michaux's name has been independently derived from the 

 Greek, without any reference to Ipojncea, and founded 

 upon its striking appearance, as supposed by the editor of 

 this article in Rees's Enc} clopoedia, seems altogether im- 

 probable. 



Nearly all the genera composing the Natural Order Po- 

 lemonidece, are peculiarly indigenous to America.
