Stems herbaceous or suffrutescent, tumid and separable at the nodes. 
Lvs. opposite, (at least the lower ones,) mostly stipulate, petiolate, palmately veined. 
Fis.—Peduncles terminal or opposite the leaves, sometimes axillary. 
Cal.—Sepals 5, persistent, veined, one sometimes saccate or spurred at base.

Gr. yepavos, a crane; the beaked fruit resembles a crane’s bill. 
Sepals and petals 5, regular; stamens 10, all perfect, the 5 alter- 
nate ones longer, and each with a nectariferous gland at its base ; 
fruit rostrate, at length separating into 5 long-styled, 1-seeded car- 
pels ; styles smooth inside, at length recurved from the base upwards 
and adhering by the point to the summit of the axis—— Herbaceous, 
rarely shrubby at base. Peduncles 1, 2 or 3-flowered. 
1. G. MacuLitum. WSpotied Geraniwm. 
St. erect, angular, dichotomous, retrorsely pubescent; dvs. 3—5-parted, 
lobes cuneiform and entire at base, incisely serrate above, radical ones on long 
petioles, upper ones opposite, on short petioles; pet. entire; sep. mucronate- 
awned.— Woods, &c., U.S. and Can., but rare in N. Eng. A fine species, 
worthy a place among the parlor “geraniums.” Stem 1—2f high. Leaves 
2Q—3’ diam., cleft way down, 2 at each fork. Flowers mostly in pairs, on 
unequal pedicels, often somewhat umbeled on the ends of the long peduncles. 
Root powerfully astringent. Apr.—Jn. Ae 
2. G. RopertiAnum. Herb Robert. 
St. diffuse, hairy; lvs. 3—5-parted to the base, the segments pinnatifid, 
and the pinne incisely toothed; sep. mucronate-awned, half the length of the 
entire petals.— 2, Smaller and less interesting than the preceding, in dry, rocky 
places, Can. to Va. and Ky. It has a reddish stem, with long, diffuse, weak 
branches. Leaves on long petioles, somewhat hairy, outline 14—3’ diam, with 
innatifid segments. Flowers small, pale purple. Capsules small, rugose, 
eeled. Seedssmooth. The plant has astrong disagreeable smell. May.—Sept. 
3. G. pusittumM. Weak Crane’s-biil. 
St. procumbent; dvs. reniform or roundish, deeply 5—7-parted, lobes 
3-cleft, linear; sep. hairy, acuminate, about as long as the emarginate petals.— 
@ A delicate, spreading species, growing in waste grounds, pastures, &c., L. I. 
and Western N. Y. Tvrr. Stem weak, 1f long, branching, covered with short, 
deflected hairs. Leaves opposite, divided almost to the base into 5 or 7 lobes, 
these again variously cut. Peduncles axillary, forked, bearing 2 purplish-red 
flowers in Jn. and Jl. 
4, G. Carouintinum. Carolinian Crane’s-bill. 
St. diffusely branched ; lvs. deeply 5-parted, lobes incisely toothed; ped. 
rather short and clustered on the ends of the branches; sep. mucronate-awned, 
as long as the emarginate petals.—@ Fields and hills throughout Can. and 
U.S. Stems pubescent, diffuse, 8—15’ long, swelling at the joints. Leaves 
3—1}/ diam., hairy. Flowers small, rose-colored, in pairs, and somewhat fas- 
ciculate. Seeds minutely reticulated, reddish brown, 1 in each hairy. beaked 
carpel. Jl.—Perhaps too near the following species.
