 involucrum numerous, subulate, pulverulent. Pedicels spread- 

 ing, filiform. Segments of the calyx lanceolate, acute, or ra- 

 ther <jbtuse, shorter than the tube of the corolla, pulverulent 

 on the inner side. Corolla pale purple or Hlac, with a yellow 

 . centre ; segments so deeply emarginate as to appear obcor- 

 date; orifice slightly glandular. Filamcntfs very short, in- 

 serted into the tube of the corolla, near its orifice ; anthers ob- 

 long, included. Style short ; stigma subglobose.

I have carefully compared numerous and-very perfect speci- 

 mens of this plant, collected by Cufit. Douglass, with 

 those of F. farinosa in my herbarium from England, Sweden, 

 and other parts of Europe, without being able to discover cha- 

 racters that will distinguish it as a species. The mark of the 

 crenate-dentate leaves is not of great importance, for some of 

 roy Eyrqpean specimens have the leaves quite entire, while in 

 others they are distinctly crenate. Professor Ho o k c. r, how- 

 ever, thinks the P. pusilla pf Q oldie to be very distinct 

 from P. farinosa ,■ though there can be no doubt that it is the 

 plant described above. The figure in the Edinburgh Philoso- 

 phical Jtmrnal, 1. c. t. XI. f 2. was taken from a garden spe- 

 cimen, and represents the plant with fewer flowers than it 

 bears in its native situation. n
