ancJ if the necessity for its subdivision be admitted, it will also, I 

 believe, be found most expedient to apply the name Gnnphaliitm 

 to that section to which G. luteo-albtim, sijlvaticiim, and uUginosum 

 belong, and which is characterized by its naked receptacle, its 

 involucrum connivent at top and of equal height with the truncated 

 capitulum, which consists of numerous filiform female florets in the 

 circumference, with a smaller number of hermaphrodite florets in 

 the disk, both of them ripening seeds and having a sessile capil- 

 lary deciduous pappus. 



To Gnaphalium so limited Galea piiiifolia., a shrub with nearly 

 acerose leaves, and in which all or most of the flosculi are her- 

 maphrodite and the radii of the persistent pappus somewhat thick- 

 ened upwards, cannot be referred. 



It seems, however, to approach more nearly to Antennaria, a 

 genus separated from Gnaphalium by Gaertner, but which, as he has 

 proposed it, consists of three tribes of plants sufficiently dissimilar 

 in habit and structure to justify a further subdivision ; and, what 

 is remarkable, none of them entirely agreeing with his generic 

 character. 



The first tribe consists of herbaceous plants, natives of Europe 

 and North America, having the male and female flosculi in di- 

 stinct involucra and on different individuals. To this genus the 

 name Antennaria* may remain, though descriptive of the 



pappus
