Pinguicula edentula ; nectario subulato recurvo, corolla campanulata 
breviore, quinquelobo, lobis emarginatis integerrimis, palato promi- 
nente, scapo pubescente. 
Root perennial, fibrous, slightly villous. Leaves all radical, spreading, ovate, 
with their margins incvirved, pale green, the surface studded with mi- 
nute pellucid dots, or papillae, which are soft and unctuous to the touch, 
furnished through the centre with one nerve. From the centre of these 
leaves arise 3 or 4 erect, single-flowered scapes, about 5 inches long, cy- 
lyndrical, downy. 
Calyx small, 2-lipped, the upper lip of 3, the lower of 2 oblong-lanceolate 
obtuse segments, downy on the outside. Corolla large, drooping be-

deflexed spur at the base, tube with a deep furrow on one side, running 
into a tubular palate in the interior of the corolla ; Limb divided into 
5 equal spreading, obcordate, deeply emarginated, almost semibifid lobes, 
but destitute of teeth or crenatures. The corolla is glabrous, except 
within the tube, and upon the surface of its prominent oblong, obtuse, pa- 
late,' which are downy. Stamens 2, placed at the base of the germen, one 
on each side. Filament curved, thick,a little ciliated. Anther with a single, 
terminal, transverse cell. Germen spherical, with glandular hairs. Style 
short, columnar, thick : Stigma of 2 lobes, one small and resembling a 
hook, the other a large involute white plate, ciliated at the margin, cor- 
vering entirely the upper part of the stamen. 
This beautiful species of Pinguicula was sent from the 
swampy grounds of Savannah, North America, along with many 
other rare plants, to our Botanic Garden, by Mr Wilson, an 
intelhgent gardener of that country. It blossomed in the 
stove in April, and as it continues some time in flower, it is
