H a b . English River. D r Richardson.—I think it probable that Dr Torrey’s P. lucens may be this
species, for he particularly mentions the great length of the peduncle ; and because I have P . pralongus
also from Texas and Boston, showing that it is a widely distributed plant in N. America. The real P. lucens
I do not possess from that country.
7. P . zostercefolius (S chum .); caule ancipiti stipulis liberis, foliis alternis lato-lineari-

H a b . Canada. Pursh. Drummond.-—This was only gathered with ripe fruit by Mr Drummond. What
I have received from the United States’botanists as S. caduca, does not seem to differ from this species, and
Dr Torrey (in Herb, nostr.) quotes the S. quadrangularis of Willd. as the same plant.
2. S. peduncularis (M u h l.); herbacea subsimplex, caule inermi erecto subscandente
(siccitate) angulato, foliis sublonge petiolatis ovato-subcordatis teneris glaberrimis sensim

H a b . Carlton House Fort on the Saskatchawan. D r Richardson.—This is an' herbaceous species, and
allied to'the last, though truly distinct, not only in the form of the leaves, and the downiness of the undersurface,
but in the comparatively very short peduncles.

Richardson. Drummond. Bongard. Tolmie, &e.—The most careful comparison of this and the European
S. amplexifolius have satisfied me that the two plants offer no specific distinction whatever. I prefer,
however, Michaux's name as much more characteristic.
