POLYANDRIA— POLYGYNIA. ilanunculus. 51 



Annual. June — October. 



Root of many simple fibres. Herb very variable in luxuriance, of 

 a paler hue than most of this genus, and clothed with fine, 

 silky, spreading hairs. Lower leaves on long stalks, ternate, 

 lobed and cut ; upper sessile, with 3, or more, narrower seg- 

 ments. Flower-stalks hairy, furrowed. Cal. pointed, finally 

 reflexed close to the stalk, and clothed with hairs glandular at 

 their base. Pet. of a golden yellow. Nect. covered with a scale. 

 Seeds compressed, bordered, rough on both sides, especially 

 towards the margin, with an irregular double or triple row of 

 small sharp ])rominences, first observed by Mr. E. Forster. These 

 clearly distinguish it from our other common Crowfoots, with 

 which it has been confounded ; and likewise prove the R. par- 

 vulus of Linnaeus and FL Br, to be but a starved variety of the 

 same species.

In meadows, moist pastures, and shady waste places in towns,

 others, but the hairy cali/v is spreading, not reflexed. Pet. 

 notched. Nect. covered with a notched scale. Seeds not gene- 

 rally perfected. A double variety is sometimes seen in gardens.
