199 Mr. Brown’s Observations on the 
and if the necessity for its subdivision be admitted, it will also, I 
believe, be found most expedient to apply the name Gnaphalium 
to that section to which G. luteo-album, sylvaticum, and uliginosum 
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 a a sessile capil- 
lary deciduous pappus. 
To Gnaphalium so limited Calea pinifolia, a shrub with pearl y 
acerose leaves, and in which all or most of the flosculi are her- 
maphrodite and the radii ofthe persistent pappus somewhat thick- 
ened upwards, cannot be referred. 
It seems, however, to approach more nearly to Antennaria, a 
genus separated from Gnaphalium by Gertner, 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
