Upright Meadow Crowfoot. Pet. H. Brit. t. 38./ 3. 



In meadows and pastures very common ; even on the loftiest 

 mountains. 



Perennial. June, July. 



Root somewhat tuberous, with many long simple fibres. Stem 

 2 feet high, erect, round, hollow, leafy, clothed with close- 

 pressed hairs, or bristles ; branched above, and many-flowered. 

 Radical leaves on long upright hairy footstalks, in 3 or 5 deep 

 lobes, which are variously subdivided and cut, more or less 

 hairy ; stem-leaves nearly sessile, with fewer and narrower seg- 

 ments ; uppermost much smaller, in 3 linear entire lobes ; or 

 sometimes simple and linear. Fl. bright yellow, on round even 

 stalks, covered with close hairs, and not furrowed. Cal. hairy, 

 spreading, deciduous. Nect. covered by a scale. Seeds lenti- 

 cular, smooth, with a small, slightly curved, point. 



The small variety, with scarcely more than a solitary /ower, found 

 on the Highland mountains, and brought by Mr. D. Turner from 

 wet rocks near the summit of Snowdon, is not the montanus of 

 Willdenow, but becomes, with one year's culture in a gar- 

 den, precisely our common acris. It has remained so with me 

 above 20 years. The double-flowered variety is common in 

 gardens, and not inelegant. The synonym of Gerarde, quoted 

 in Fl. Br. belongs to R. polyanthemos, a foreign species, with 

 furrowedjlower-stalks, and more finely divided leaves, of which 

 the wooden cuts, in old books, are, as Prof. DeCandolle well 

 observes, hard to distinguish from those of the acris. 



12. R. arvensis. Corn Crowfoot. 



Seeds very prickly at the sides. Leaves once or twice deeply 

 three-cleft, with linear-lanceolate segments. Stem erect, 

 much branched, many-flowered.
