In my ' Prodromus Floras Nepalensis,' I had proposed 
to unite this genus to Gnaphalium^ although it would cer- 
tainly have been much more natural to have placed it with 
Antennaria, in which it had been included by Gsertner. 
The truncate polygamous flowers, the hemispherical, non- 
scariose, rayless involucrum, and the simple setae at the 
base of the anthers, alone distinguish it from Antennaria ; 
but as these characters, joined to the remarkable bractese, 
appear to warrant such a separation, I have willingly fol- 
lowed Mr Brown in the expediency of keeping them distinct. 
Both species are polygamous ; that is, they have either se- 
parate stalks bearing male and female heads of flowers from 
the same root, or the centre involucrum in each head is 
male, and surrounded by several female ones. The female 
involucra are constantly furnished with some male florets, 
and the male involucra with either female, or neuter ones.
