lauceolata |-supera. — Rio Blanco, in shaded rocky places, rare ; Sep- 

 tember. (552,) A very interesting accession to this genus, all the 

 more so because discovered by Dr. Palmer himself. It requires some 

 extension of the generic character, beyond that referred to in S}n. 

 Flora, Suppl. 394. The ovary is almost free, as in several species of 

 Lobelia; the gibbosity at the base of the corolla is well marked, and 

 the stamens are very unequally adnate to its tube on the side of the 

 gibbosity, not beyond the middle.
