POLYANDRIA— MONOGYNIA, Nymphsea. 13. 



moreland, plentifully. Hudson. In shady lanes near Kirkby 

 Lonsdale. 



Perennial. Jutie. 



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 3 leaflets nearly ovate, acute, cut, lobed, or pinnatifid, 

 smooth, somewhat decurrent ; most glaucous underneath. FL of 

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

 sula coccinea and odoratissima, or Mesemhnjanthemum noctifio- 

 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 Gsertner, t. 60. which has 

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

 titions, of Papaver.

Cal. inferior, of 4 large, coriaceous, oblong, permanent 

 leaves, coloured on the upper side. Pet. numerous, ob- 

 long, placed in several rows upon the base of the germen. 

 Nect. globose, in the centre of the stigma. Filam. very nu- 

 merous, flat, placed on the germen above the petals ; the 

 outermost gradually dilated. A7ith. linear, of 2 parallel 

 cells, closely attached, in their whole length, to the inner 

 surface of the upper part of each filament. Germ, superior, 

 sessile, globose. Style none. Stigma orbicular, sessile, 

 of numerous rays, pointed and separate at the extremity, 

 permanent. Berry coriaceous, scarred, of as many cells 

 as there are rays; at length internally gelatinous and 

 pulpy. Seeds numerous in each- cell, roundish. 



Large, smooth, aquatic, perennial herbs. Stem none. 

 Leaves floating, on long footstalks, heart-shaped or pel-
