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 pui-plish hue at the plaits when dried. 



We are not aware that this variety has been introduced 

 till now. 



Root tuberous, large, oblong, perennial. Stetris her- 

 baceous, six or seven feet high, twining, branched, streaked. 

 Leaves pubescent, cordate, tomentose underneath, 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. Cal^x 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 limbj which in the present specimen was wrinkled, 

 much in the way of the petals of some of the Cisti. Stamens 

 and sti/le not protruding beyond the tube : stigma capitate, 

 slightly hilohed: ^laments slightly furred with purple villi. 

 Seeds covered with a silky fur. 



We are obliged to Mr. Herbert and to the descrip- 

 tion by Mods. Desfontaines, for what we have said of the 

 plant.
