[I prefer this name to polifolium, because 

 Linneeus describes the latter Calycibus lavibus, 

 as opposed to Calycibus hispidis of the neigh- 

 bouring species.] 



43. pilosum. Stem twisted at base. 

 Branches slender, erect, " rarely a little ascend- 

 ing towards the base." L. small, very narrow 

 and closely revolute on margin. Cal. and 

 Caps, small, -w, Narb. Prov. — Jordan. 



[I do not mark this as a quotation, because I 

 do not know if I have extracted from his de- 

 tailed description the characters on which Mr. 

 Jordan would depend. He distinguishes also, 



apenninum, with flat, oval, oblong L. Sepals 

 downy. ■ 



polifolizim, with flat, oval, oblong L. Sepals 

 shining. This he adopts from DC. without 

 being acquainted with the plant. 



pulverulentum, with oblong or linear L., 

 somewhat revolute on the margin. Branches 

 spreading. 



velutinum. L. oblong or linear-oblong, at 

 last flat. Branches erect. 



— All of which seem to me to belong to H. 



pulverulentum. 1

 Beet. 



45. Thibaudi. "Tomentose. L. linear. 

 Margin revolute. Fl. cernuous, fringed with 

 glands. Sepals oblique, somewhat three-edged ; 

 outer lanceolate, reflexed. Sepals resembling 

 the elytra of an insect, w. Corsica." — 

 Pers. from Herbariimi of Thibaud. This 

 seems a remarkable -plant, but it is not noticed 

 by DC, Duby, or Bert. Is it possible that 

 Per soon took for sepals the open valves of the 

 capsule ?
