YELLOW GROUP 



Hooked Crowfoot 



R, recurvktus — Color, pale yellow. Sepals and petals, 5, pointed, 

 the sepals rellexed, longer than the petals. Fruit, a cluster of 

 achenes armed with a long, recurved hook, whence the common 

 name. Stem, hairy, 1 to 2 feet long, strong, woody. Flowers, parc- 

 eled in the leaf-axils. Leaves, with long petioles, the lower ones large, 

 all 3-cleft, more or less toothed toward the apex. May and June. 



Open woods, common in New England States and south- 

 ward. Not especially pretty. 



Early Crowfoot 



R. fasciculkris. — Color, bright yellow. Sepals, 5. Petals, 5, 6, 

 or 7, much larger than the sepals. The first root-leaves are round- 

 ish, 3-parted, toothed. Later ones have a central stalked lobe 

 larger than the lateral segments, all much divided or parted. 

 Upper stem-leaves linear, undivided. Plant very leafy and silky, 

 with soft, white hairs. Roots clustered, thick, fleshy, giving the 

 specific name. 6 to 12 inches high. April and May. 



Hillsides and open woods, common. Low, bright, and 

 pretty, a companion to violets and anemones, being similar 

 and related to our common buttercups. 



Swamp Buttercup 



R. septentrionklis Color, yellow. Petals, larger than the 



sepals. Most of the stems ascend, but some lie upon the ground 

 and produce runners. Leaves, 3-divided, the divisions irregularly 

 cut, the leaflets stalked or sessile. Achenes beaked. 1 to 3 feet 

 high. May to August. 



Wet meadows and low grounds. 



Creeping Buttercup 



R. repens. — This is much like the last in flowers and leaves. 

 The latter are often variegated with white spots. It is probably 

 an introduced species, but is quite common in wet meadows and 

 low grounds, seemingly indigenous westward. It is of a creeping 

 habit Flowers one inch across. 



Bristly Crowfoot 



R. pennsyl<v£nicus. — The flowers of this species are small, with 

 the 5 sepals turned back. The head of achenes is long, cylindrical. 

 Leaves, divided into threes, the divisions stalked and irregularly 

 cut or toothed. Stem, stout, erect, beset with bristly hairs. June 

 to August. 



In wet ditches, low grounds, and meadows from Maine to 

 Georgia and westward.
