NORTH AMERICAN AMARELLA. 53 
sive withit; Adanson’s Opuntia being the same group amplified 
by the admission into it of Petreskia. 
I account it a happy outcome of the present study, that I am 
able to say Necker’s names for cactaceous genera are all mere 
synonyms. 
North American Species of Amarella. 
The Old World Gentiana 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 dotibt 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 Rafinesque 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 AMARELLA, I do not comprehend. 
Even from the Linnxan date as initial Gilibert restored the 
genus and the name AMARELLA some thirteen years ante- 
riorly to the publication of Gentianella. 
The following are some of our AMARELLA species, over and 
above those transferred by Rafinesque: A. AURICULATA (Pall. 
Fl. Ross. ii, t. 92, f. 1), PLEBEIA (Cham. in Bunge, Gent.), 
HETEROSEPALA (Engelm. Trans. Acad. St. L. ii, 215, t. 8,) 
WRIGHTII (Gray, Syn. FI. ii. 118), TENUIS (Griseb. Gent. 250), 
STRICTIFLORA (Rydb. Fl. Mont. 309), ANISOSEPALA (Greene, 
Pitt. iii, 309), WisLizENI (Engelm. l. c.), ARCTOPHILA (Griseb. 
Lei AMARELLOIDES (Michx. Fl, i, 175), OCCIDENTALIS (Gray, 
Man. 1 ed. 359), proprnqua (Rich. App. 734), DISTEGIA (Greene, 
Pitt. iv, 182), microcaLyx (Lemmon). 
The following may be indicated as new: 
A. CoPELANDI. Gentiana Copelandi, Greene, in Baker distr. 
of 1903, n. 3849. Erect, sparingly branching, 2 to 8 inches

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