142 I, RANUNCULACES. - Ranonounus, 
y. filiformis. DC. (R. filiformis. Michz.) St. filiform, very long, with 
linear leaves and small flowers. 
3. R. pusittus. Poir. 8. muticus. T. & G. Puwny Crowfoot. 
Erect; /vs. all petiolate, lower ones ovate, upper ones linear lanceolate ; 
pet. mostly but 3, scarcely longer than the calyx ; carpels ovate, pointless, smooth, 
in small globose heads.—In wet grounds, N. Y. and Penn. Stems slender, 
weak, 6—12’ high, dichotomously branched. Lower leaves subcordate, 3—1" 
long, # as wide, petioles 1—3” long, upper ones 1—13” long, } as wide, with 
minute, remote teeth. Flowers very small, yellow, on long peduncles. May. 
4, R. Cympauaria. Ph. Sea Crowfoot. 
Very small, smooth; sé. filiform, creeping, rooting at the joints; ls. reni- 
form-cordate, crenate-dentate ; ped. solitary. mostly 2-flowered; pet. spatulate ; 
ach. oblong.—In salt marshes on the sea-coast, N. J. to Arctic Am. and at 
Salina, N. Y. Stem round, sending out runners from the joints. Leaves radi- 
cal, 4—1’ diam., on long petioles. Scapes 2—6’ high, each with 2 or 3 small, 
bright yellow flowers, and as many obtuse bracts. Nectary naked. Jn. 
* * Leaves divided. 
5. R. aBortivus. Round-leaved Crowfoot. 
_ Smooth; radical lvs. roundish, cordate at base, crenate, petiolate; caulne 
ws. ternate or pedate, angular, with linear segments, wpper ones sessile; cal. a 
little longer than petals, reflexed.—A very pretty species in woods, Can. to Ark., 
remarkable for the dissimilarity of the root and stem leaves. Stem 8—16’ 
high, nearly naked. Root leaves 8—18” diam., quite regularly margined with 
crenate divisions, and on petioles 2—5/ long. Lower stem leaves pedate, with 
a pentangular outline; upper in 3 deep segments. Flowers small, yellow. 
Fruit in globose heads. May. Jn. 
6. R. sceteritus. Ph. Celery Crowfoot. See also Addenda, p. 638. 
Smooth ; lower lvs. 3-parted, segments 3-lobed, crenately subincised ; stem 
lvs. 3-parted, segments crenately incised, wpper ones simple, lanceolate, entire ; 
carpels in an oblong head.—Grows in wet places, Can. to Car. Stem rather 
thick, hollow, much branched, 1—134f high. Lower petioles 3—5/ long, with 
rather large, palmately 3—5-parted leaves. Floral leaves or bracts mostly 
simple, lanceolate and entire. Flowers numerous, small, yellow. Calyx 
deflexed. This is one of the most acrid of the tribe, and will raise blisters 
upon the skin. Jn. Jl. 
7. R. recurvatus. Wood Crowfoot. 
St. erect, and with the petioles, covered with spreading hairs; lws. 3-parted. 
hairy, segments oval, unequally incised, the lateral ones 2-lobed; cad. recurved; 
pet. linear-lanceolate ; ach. uncinate——About 1 f. high, in damp woods, Lab. 
to Ga., pale green, branching above. Leaves 14—2’ long, 2—3}4/ wide, on peti- 
oles 3—6’ long. Upper leaves subsessile and 3-parted quite to the base. 
Flowers small, with inconspicuous, pale yellow petals. Carpels ovate, tipped 
with minute, hooked beaks. May.—Jl. 
8. R. acris. Butter-cups. Crowfoot. Yellow Weed. 
St. erect, many flowered ; lvs. more or less pubescent, deeply trifid, the seg- 
ments laciniate, wpper ones with linear segments; ped. round; cal. hairy, 
spreading; carpels roundish, smooth, compressed; beak short, recurved.—This 
is the most common species from Penn. to Hudson’s Bay, in meadows and 
pastures, rapidly and extensively spreading. Stem 1—2f high, round, hollow, 
mostly hairy. Leaves 14—3/diam., upper ones in 3 linearsegments. Flowers 
large, golden yellow. Jn.—Sept. ; 
B. Fis. double, the pet. excessively multiplied.—Gardens. 
9. R. punzosus. Bulbous Crowfoot. (Fig. 39.) 
Hairy; st. erect, bulbous at the base; radical lvs. ternate, /fts. petiolate, 
incisely dentate, each about 3-cleft; ped. furrowed; cal. reflexed.—This is 
another acrid species, very common in pastures, mow-lands, &c. Root fleshy. 
Sa leafy, furrowed, 6—18’ high, hollow, thickened at the base into a sort 
bulb, and dividing above into upright peduncles, with golden-yellow flowers. 
It is well distinguished from R. acris by its reflexed sepals, and its furrowed
