flowers, Mr. Herbert informs us, expanded about 9 o’clock 
at night, and continued in beauty about twenty-four hours. 
When the corolla is fresh, the limb is of a pure white, but 
assumes a purplish hue at the plaits when dried. 
We are not aware that this variety has been introduced 
till now. 
Root tuberous, large, oblong, perennial. Stems her- 
baceous, six or seven feet high, twining, branched, streaked. 
Leaves pubescent, cordate, ‘tomentose under neath, entire or 
from two to seven-lobed, nerved: petiole twice shorter than 
the blade. Peduncles axillary, solitary, pubescent, shorter 
than the leaf, about threeflowered; pedicles furnished with 
two opposite glands and two very small oval caducous bractes 
at. the base. © Calyx palish green, villous, oblongly oval, 
about two thirds of an inch long; segments oval, obtuse, 
nearly equal, converging closely round the lower part of the 
tube of the corolla. Corolla finely pubescent at the outside, 
hypocrateriform; tube nearly two inches long, cylindrical, 
but little enlarged at the upper part, nearly twice longer 
than the limb, which in the present specimen was wrinkled, 
much in the way of the petals of some of the Cist1. Stamens 
and style not protruding beyond the tube: s#zgma capitate; 
slightly bilobed: filaments slightly furred with purple villi. 
Seeds covered with a silky fur. 
We are obliged to Mr. Herbert and to the descrip- 
tion by Mons: Desfontaines, for what we have said of the 
plant.
