spreading, distinctly unguiculate, twice the length of the calyx-lobes, 5 mm. 

 long ; lamina broadly ovate, obtuse at the apex, subtruncato-obtnse and decur- 

 rent to the unguis at the base,obscurely and minutely serrulate on margin, 

 sub-5-nerved, deciduous ; unguis J as long as the the lamina, narrower 

 below. Stamens 5, slightly exceeding the calyx-lobes ; filament subulate, 

 white; anther broadly rounded, emarginate at the apex, bilobed at the 

 base, the cell semiorbicular. Staminodes 5, slightly shorter than the calyx- 

 lobes, spathulate; the lamina broadly deltoid-flabellate, truncate and with 

 a comb of 5-6 finger-like short brandies, which are unequal in length and 

 merely obtuse (no globule) at the end, 1 mm. or a little more across ; the 

 stipitate portion rectangular. Pistil equal to the calyx-lobes in height ; 

 ovary ovoid, sessile, smooth, green, with 3 parietal placentas, many-ovuled ; 

 style very short ; stigmas 3, conspicuous, erect-patent and slightly recurved, 

 elliptical-oblong, ubtuf^e. Capsule (immature) globose, green, crowned

Bare. By the much smaller and more delicate habit, the reniforra 

 leaves, the long-unguiculate petals, the staminodes with shorter fewer and 

 not capitellate branches, and 3-carpellary ovary, etc., present one should be 

 specifically separated from Parnassia palustt'is Linn.
