Fall-lands, etc.] FLORA ANTARCTICA. 311 



A very minute species, which at one time I was inclined to consider a seedling state of G. spicatum-, but the 

 whole plant is perfectly glabrous, the stems very slender, the capitula aggregated at the apex of the stem and 

 much smaller than those of G. spicatum. 



I regret having found but few specimens of this very minute Gnaphalium, they were quite concealed amongst 

 the stems of grasses and other herbs.

This plant seems identical with Hartweg's n. 314 of Mexico, which Mr. Bentham has named G. inornatum, DC, 

 but I can distinguish neither from European and N. American specimens of G. luteo-album, which is a very frequent 

 inhabitant of the wanner and temperate parts of the globe.

In the sphacelated apices of the involucral scales, this genus approaches Senecio, from which it essentially 

 differs in the fomi of the florets of the circumference, which refers it to DeCandolle's second division Frect/utea 

 of the Senecionea. Its habit and foliage are different from other Antarctic plants, though it resembles some alpine 

 Composites of New Zealand.
