The single aud most imsatisfactor}' specimen may possibly belong to tliis species, which is veiy imperfectly defined
in the work quoted. Upper portion of stem, cauline leaf, pedimcle, pedicel and caljoc, covered with appressed
pubescence, retrorse on the pedimcles aud petioles, veiy dense upwards on these parts. Petals cimcate, shorter than
the sepals, w'hich are attenuated into long aristæ.

One of the most ordinary forms of the genus, the species composing which, are perhaps more variable in aU their
parts and more widely diffused than is generaUy supposed. Except by the length of its petals, this is not distinguishable
from the G. albicans, St. Hil., and the protean G. Caroliniamm of North America ; we have the same plant
from Monte Video, and Port Desire, hut uot from the west coast of South America, and a very similai’ species from
Australia.

An easüy recognized species in the state I have examined, by its habit, the size of the root, and the short peduncles,
and branches or stem, which are however characters very liable to vary. Though placed by authors in the
single-flowered section as the peduncles often bear two flowers.
The genus Geranium, though so widely dispersed, hardly inhabits the coldest countries either of the Northern
or opposite Hemisphere, the Strait of Magalhaens marking its southem Umit in the New, and Lord Auckland’s
group, or latitude 50°, in the Old World. In Arctic America, no species crosses the parallel of 52° to the eastward
of the rocky moimtains, but one {G. erianthum) reaches Sitka latitude 59° on the west of that range. In Asia
that plant inhabits the same latitude in Kamschatka. No European species, except G. sylvaticum (the only Alpine
English one), crosses the Arctic circle, whüe three are found in Iceland, the northern extremity of which stretches to
tliat parallel. One of tKe thirteen British species, O. moUe, gi'ows in the Shetland Islands. The Gerania abound ou
the lofty mountains of the tropics, at elevations where the climate is temperate, proceeding upwards to near the
verge of perpetual snow. Professor Jameson states that tlu-ee gi-ow on the Andes of Columbia, between 12,000 and
14.000 feet, whUe on the Himalayah momitams only one species is seen below 5,000 feet, between which height and
1.2.000 the gcnns is limited.
