prove perfectly hardy, flowermg in July and August. 
Descr. Root, or rather subterraneous stem, much creep- 
ing, rounded, about the thickness of a goose-quill, here and 
there sending out fibrous radicles from the underside, and 
leaves from the upper, which latter are solitary or two 
together, erect, four to six inches long, oval, obtuse, ob- 
scurely and distantly toothed, running down at the base 
into a rounded, purplish petiole. The surface of the leaf is 
distinctly marked with nerves, and is full green above, 
paler below. Peduncle from the base of a leaf, or be- 
tween two leaves, about as long as the petiole, rounded, 
erect, bearing a solitary, upright flower. Calyx small, cup- 
shaped, five-cleft. Corolla large, externally pale yellow 
green, internally white. Tube long, rather thick, curved ; 
limb of five lanceolate, much acuminate, spreading seg- 
ments. Anthers five, oblong-ovate, acute, sessile, or rather 
the filaments are combined with the tube of the corolla. 
Germen small, ovato-globose. Style exserted, much longer 
than the tube: Stigma clavate, three to five-cleft : the seg- 
ments erect, green.
