strictly ascertained. Since then it has been included by 
Monsieur Richard, in his order of Zentibularie or Bladder- 
wort-tribe, consisting of aquatic or marshy plants, the cha- 
racter of which has been still more recently defined by Mr. 
Brown. 
The generic appellation of PrucurcurLA refers to the 
unctuous shining appearance of the foliage of the common 
european species; so do the english and french ones of 
Buiterwort and Grassette. 5 
Lutea is a native of North America, where it grows in 
the pine-barrens of Lower Carolina, and differs from its 
congeners by a yellow crenated corolla, with a tufted pro- 
truded palate. It has been now first introduced by Messrs. 
Colvilles, nurserymen in the King's Road, Chelsea, who 
flowered it last May in pots of bog-earth, placed in pans of 
water on the flue of their hothouse. The plants had been 
sent them by Mr. Nuttall, a very intelligent collector, now 
in America. 
Root perennial. Leaves radical, multifarious, imbricately 
ambient, spreading, ovate obtuse, an inch or more in 
length, vesicularly speckled. Scapes from the root, 2-3, one- 
flowered, filiform, upright, 9-7 inches high, covered with 
short glandularly capitate hairs. Calyr green, with a 
greyish pubescence, segments blunt. Corolla about three 
fourths of an inch or more across, obsoletely bilabiate ; 
limb flat, nearly egual, resupinate, the two segments of, the 
upper lip (by the inversion of the flower become the iaer) 
obcordate, rather narrower, deeply emarginate, converging 
at their inner margins, the three of the lacér (by inversion 
the upper) cuneately obcordate, each crenated with about 
4 incisions ; palate bearded, deep yellow, protruded beyond 
the orifice of the tube of the corolla; spur 3 times or more 
shorter than the corolla, subulate, pointing downwards 
with a curve. Stigma subpetaloid, unequally bilabiate, 
placed transversely on the germen, and consisting of two 
flat laminar lobes, the lowermost and largest of which bends 
itself downwards, so as to lap over the two stamens inserted 
below the base of the germen in front, assuming an upright 
direction when the anthers have parted with the pollen; 
the upper lip or laminar lobe is several times smaller, pa- 
rallel with the back of the larger. Germen uniloculaf, 
speckled with small whitish pustules.
