26 PLANTE FENDLERIANS. 
in diameter ; the lower rounded-reniform in outline, the upper with the three principal 
segments divaricate. Corolla when fully expanded an inch or less in diameter, deep 
purple. — Well distinguished from its allies, as Dr. Engelmann remarks, by its long fila- 
ments, which are recurved-spreading in anthesis, and by the much clongated peduncles 
with comparatively short pedicels. Dr. Engelmann had indicated it as a new species ; 
but I am so confident that it is the species noticed and imperfectly characterized by Dr. 
James, that I venture to revive his name, which, unless thus identified, must ever remain 
appended to the genus as a doubtful species, since no specimens of it exist in the collec- 
tion made by him in Long’s Expedition.

Bottom lands of the Mora River, among shrubs; August. (Also in the Raton Moun- 
tains, Lieut. Abert, and probably farther north and west by Col. Fremont.) — Stems 
weak, at first erect, two feet high. Radical leaves 2 or 3 inches in diameter. Pedun- 
cles 3 to 2 inches, the pedicels 1 to 3 inches, in length. Flowers larger than in the pre- 
ceding, from which it is readily distinguished. Dr. Engelmann remarks, that it is “rather 
too near G. pentagynum [which I suspect is G. incisum, Nutt.]; but may be distinguish- 
ed by the slender stem, the broadly cordate or truncate base of the leaves, the shorter 
points of the sepals, &c. G. pentagynum is remarkably stiff and erect; the leaves 
deeply cordate, thick, silky with a fine appressed pubescence, and with prominent veins.” 
Fendler’s specimen, like one of Lieut. Abert’s, is rather less pubescent and more diffuse 
than the original one of Fremont, the petals of which would appear to have been pale 
purple, if not white. In the others they are light purple, with deeper-colored veins,* 
* Dr. Engelmann, who has attentively studied our Gerania, 
proposes the following disposition of the North 
American species of this group, viz. : — . 
erennes ; pedunculi biflori ; valvula capsule leves, plus minus pilose ; semina reticulata seu rugosa. 
* Pedicelli deflorati erecti seu suberecti.
