302 Mr. D. Don's Descriptions of new Genera and Species 



Diazeuxis? serrata, p. 254. 



In a collection of dried plants, which Mr. Lambert lately 

 received from Messrs. Schiede and Deppe, is a specimen in 

 flower of this plant, which proves to be a genus akin to Serra- 

 tula ; and it is therefore to be expunged from Diazeuxis, to 

 which it had been referred from habit alone, and the following 

 inserted in its place. 



2. D. latifolia, foliis lanceolatis acuminatis triplinerviis basi at- 

 tenuatis, involucri squamis ovato-lanceolatis, pappi foemi- 

 nei radiis fasciculatis.

Mutisia, p. 260. 

 I oua-ht to have added to my remarks on this genus, that the 

 presence or absence of appendages to the scales of the invo- 

 lucrum is a character of specific importance only, as may be 

 seen by a comparison of species intimately allied, such as Mu- 

 tisia Clematis and lanata, and M. inflexa and linearifolia. I have 

 now satisfied myself as to the identity of Mutisia grandiflora of 

 Humboldt and Bonpland with the M. Clematis of Linnaeus, from
