H ab. Both forms occur in Canada. Mr. Cleghom. Lake Huron. Dr. Todd.—It is indeed with regret
that I must apply a new name to a plant so well known and widely dispersed ; but it seemed necessary to
call that plant of Linnaeus which has been proved to be identical with that of Walter G. Saponaria. The
confusion of these species arose from Froelich’s Monograph, who confounded this species with G. Saponaria
of Linnaeus, of which he knew only the variety /3; but that did not agree with Linnaeus’s diagnosis,
and was therefore described by him as a new species. The confusion increased, when Michaux took the
G. ochroleuca for Linnaeus’ G. Saponaria. The G.puberula of the former is now a doubtful synonym,
all species of this group being occasionally rough. If Pursh was right in referring it to G. linearis, F., it
belongs to G. Saponaria, L., and would differ from G. Pneumonanthe, Mich, merely by the form of the
plica ; but as G. Andrewsii is the commoner plant of the two, it is probable that Michaux designated by his
G.puberula the variety /3. of the latter, in which case his name should be adopted. It is desirable that this
question should be determined by the inspection of Michaux’s herbarium. Pursh does not seem to have
'well examined these species, as he quotes for his G. Saponaria the plates as well of Andrews as of Sims.
He may have considered both the narrow-leaved varieties as one species, viz. his G. linearis, and the chief
forms of both species as belonging to a second. This makes indeed the synonym of G. pubentla Mich,
the more doubtful: the corolla in both forms is described by Pursh in the same way, and indeed most unsatisfactorily.
The best description of G. Andrewsii has been published by Elliott.

H ab. Canada. Mr. Goldie. Grows in sandy fields.—The two preceding species prefer a fat and
somewhat humid soil. It is remarkable how much the form of the leaves varies in these species. The
most frequent form of G. ochroleuca is perhaps an obovate leaf, but the broadest part is also very often
near its base; I have seen many specimens with cordato-lanceolate leaves. Muhlenberg, however, sent
to Willdenow a specimen, the leaves of which are almost orbicular. It never occurs so narrow-leaved as
the varieties of the preceding species, but generally the form of the foliage is analogous to that of G. Saponaria,
while G. Andrewsii has commonly longer and narrower leaves, the broadest part of which is near
their base. With respect to the similar variableness of the corolla, see the excellent observations of Sir
W. Hooker, in the Companion to the Bot. Mag. 1. c.

species stands indeed very near those above mentioned.
