on our return across the Port de Cauteret, which we accom- 

 plished on the 6th, proceeding on foot as far as Cauteret, and 

 thence in a caleche to Argelez the same evening.

* No. 32 Coll. I believe this the true plant of Willdenow. The follow- 

 ing character is from my notes, " Folia lanceolato-spathulata basi angus- 

 tata, pube stellato-ramosa subtomentosa. Pedicelli glaberrimi. Calyx 

 parce pilosus. Silicula lanceolata s. elliptico-lanceolata." It is, perhaps, 

 the D. Wahlenbergii, Hartm. ]8. heterotricha, Lindbl. of Koch's Synopsis, 

 Ed. 2, p. 69, and is apparently intermediate between this species and D. 

 Johannis, Host. : agreeing with the former in the aphyllous or monophyllous 

 scape, and with the latter in the stellato-pubescent leaves. 



t No 51 Coll. This includes two plants, a smaller and single-flowered 

 one, and a larger branched plant, which I joined on examination, but am 

 now disposed to keep apart. The former I refer to D. hirtus, Vill. ; the 

 latter approaches closely to D. brachyanthus, Boiss , but has not the calyx 

 ventricose at the base as in that species. I am informed by M.J. Gay, 

 that he gathered the very same plant, in the same locality, twenty-three 

 years ago, and that he has since kept it in his herbarium without any 

 accurate determination. M. Planchon has compared the two with exam- 

 ples in the Hookerian herb., and considers them both forms of D. hirtus.
