broad scarious ciliated wing. Corolla tube downy. Capsule imper- 

 fectly 3- or 4-celled. Seeds 1 in each cell, flat on the inner face. Plant 

 generally more or less pubescent ; scapes almost always pubescent. 



On sandy commons, roadsides, waste places, and chalky banks.

Very variable in size, and also in the lobing of the leaves, which are 

 from 1 to 12 inches long. Scapes 2 to 18 inches long, generally 

 decumbent at the base. Rootstock with one or more crowns; in dry 

 situations Avith the leaves sjireading flat on the ground, and the scapes 

 decumbent at the base : in damper places the leaves are ascending or 

 erect. Spikes slender, i to 2 inches long, recurved-reclinate before 

 the flowers expand. Anthers pale yellow. 



The long point to the bracts, strongly winged sepals, and 3- or 4- 

 celled and seeded capsule, readily distinguish the entire leaved forms 

 from P. maritima, to which they bear some resemblance. The much 

 commoner pinnatifid-leaved forms cannot be confounded with any other 

 British species.
