KOETH AMBEIOAN AMAEELLA. 53 



sive with it ; Adanson's Opuntia being the same group amplified 

 by the admission into it of Peireskia. 



I account it a happy outcome of the present study, that I am 

 able to say ISTecker's names for cactaceous genera are all mere 

 synonyms. 



North American Species of Atnarella. 



The Old World Geniiana lutea being typical for the genus 

 Gentiana, it has long been clear to me that in the New World 

 we have no plants congeric with it, and that the very name Gen- 

 tiana ought to disappear from American indigenous botany ; and 

 I have no doubt that will come to pass in the books of some not 

 far distant future. An initiative in this, which I conceive to 

 have been the right direction, was made by Eafinesque before 

 the middle of the nineteenth century ; and Mr. Small now, in 

 the beginning of the twentieth century, reasserts such a propo- 

 sition. But why, in his Flora, he should have adopted the 

 comparatively recent name Gentianella instead of the much 

 older Amaeella, I do not comprehend. 



Even from the Linnsean date as initial Gilibert restored the 

 genus and the name Amaeella some thirteen years ante- 

 riorly to the publication of Gentianella. 



The following are some of our Amaeella species, over and 

 above those transferred by Rafinesque: A. aueiculata (Pall. 

 PI. Eoss. ii, t. 92, f. 1), plebeia (Cham, in Bunge, Gent.), 

 HBTEEOSEPALA (Engelm. Trans. Acad. St. L. ii, 315, t. 8,) 

 Weightii (Gray, Syn. Fl. ii. 118), tenuis (Griseb. Gent. 250), 

 STEiCTiELOEA (Rydb. Fl. Mont. 309), anisosepala (Greene, 

 Pitt, iii, 309), Wislizeni (Engelm. 1. c), aectophila (Griseb. 

 1. c), AMAEELLOiDES (Michs. Fl, i, 175), occiDESTTALis (Gray, 

 Man. 1 ed. 359), propinqua (Eich. App. 734), distbgia (Greene, 

 Pitt, iv, 182), MiCEOCALTX (Lemmon). 



The following may be indicated as new : 



A. OoPELANDi. Gentiana Copelandi, Greene, in Baker distr. 

 of 1903, n. 3849. Erect, sparingly branching, 2 to 8 inches 

 high, florif erous throughout, only sparsely leafy, the internodes 1 

 to 2 inches long and leaves small, the lowest cuneate-obovate.
