I subjoin the description of C. Pennsylvanica, Donn., which must be 
regarded as a synonymn of C. Virginiana, L. 
“OQ, Pennsylvanica, Donn.—Plant glabrous, the stem somewhat 
climbing above ; leaves ternately cut, the segments petiolate, ovate- 
oblong, acuminate, a few coarse teeth toward the apex, the base entire, 
and 3-5 nerved; peduncle axillary, frequently shorter than the petiole, 
3-flowered, 3-bracted ; flower hermaphrodite ; sepals 4, linear-oblong, 
rather obtuse, velvety without. 
“T find dried branches, about a foot long, in the herbarium of Prof. 
de la Vyne (?), long since deceased, very much like plants cultivated 
in German gardens since the time of Schreber. - Flowers (on these 
branches) in threes, lateral, not yet expanded, each flower subtended 
by a leaf like, serrulate or entire bract ; the bract of the middle flower 
often already fallen. These peduncles at the time of evolution (or 
flowering), short, afterwards perhaps elongated. Flowers small, 
whitish. Stamens in a single series, flat, brownish. Ovary terminated 
by plumose styles.” (Turez. Bull. Soc. Moscow, vol. xxvii. p. 273.) 
This description is very imperfect, and not sufficient to establish or 
characterize a species. It corresponds very well to some forms of C. 
Virginiana, and to that species is here referred. No habitat is given 
for it. 
In the following table the species are arranged according to what 
seems their most natural affinities:
