The genus GnaphaUum, as now limited, forms a very- 
natural and distinct group. It is abundantly characterised 
by having its male and female florets in the same involu- 
crum, and by the uniformity of its pappus in both sexes. 
In the structure of its flowers, Gnaphalium has a striking 
analogy to Erigeron, as constituted by me in the ' Prodro- 
mus Florae Nepalensis but the latter differs essentially in 
the anthers being destitute of setae at their base. This ge- 
nus forms, through the Conyzeae, the transition to the Aste^ 
7'edB, the family to which Erigeron belongs. The species 
belonging to this genus are, GjiapJialium germanicum Sm., 
arvense Willd., montanum Willd., gallicum Sm., pyramid 
datum Willd. (all included by Linnaeus in his genus Filor- 
go), uliginosum L., minimum Sm. ,^uscim Scop., pusillu7n
