POLYANDRIA-^MONOGYNIA. Nymphaea. 13 



moreland, plentifully. Hudson. In shady lanes near Kirkby 

 Lonsdale. 



Perennial. June. 



Herbage tender, brittle, of a light, slightly glaucous, green ; its 

 juice lemon- coloured. Stem a foot high, mostly besprinkled 

 with nearly upright hairs, leafy, branched. Leaves stalked, pin- 

 nate ; leaflets nearly ovate, acute, cut, lobed, or pinnatifid, 

 smooth, somewhat decurrent j most glaucous underneath. Fl. of 

 a most elegant full lemon-colour, deliciously fragrant like Cras- 

 sula coccinea and odoratissima , or Mesembryanthemum noctifto- 

 rum ; smaller than P. Rhceas ; each on a very long, minutely 

 hairy stalk. Cal. hairy. Caps, elliptic-oblong, of 4 or 5 cells, 

 with as many ribs, or receptacles, which elevate the convex, 4- 

 or 5 -rayed, stigma, and, before the capsule bursts by interme- 

 diate valves at the top, have the appearance of a short style. By 

 this character the present species has been separated from Pa- 

 paver, by some able botanists, but I think on insufficient grounds, 

 whatever may be the true nature of certain American plants as- 

 sociated with it, which I have not sufficiently investigated. Ex- 

 cept the elongation just described, this capsule has much of the 

 structure of Argemone mexicana, see Gaertner, t. 60, which has 

 but slight traces of the dilated receptacles, or imperfect par- 

 titions, of Papaver.
