 Gnaphalium spicatum, Lam., Encyc, ii, 757. 



Caballero (602). January. 



Of the species of Gnaphalium here noted, no. 793 is the most 

 striking. It grows 4-9 dm. high, with a glandular, webby-haired 

 stem, crowded, oblanceolate leaves 8-10 cm. long, and a densely 

 crowded corymb of large heads. It reminded me in looks of an 

 overgrown Anaphalis margaritacea. No. 32 is very common in 

 open grounds both in Paraguay and the Argentine Republic. No. 

 602 is a slender, erect species, 3-6 dm. high, very silvery-white on 

 the stem and leaves. Flowers in small clusters at the ends of nearly 

 erect branches, the scales pale brown in tint. 



Acanthospermum liispidum, D.C., Prod., v, 522. 



Asuncion (162). November. 



We may well be thankful that of the 2 only known species (or 4 

 according to DeCandolle) of Acanthospermum, both of which are 

 South American, but one (A. xanthioides) has found its way into 

 our country. The sharp, 4-spined achenia, produced in great abund- 

 ance, are very annoying. The bare-footed natives of Paraguay 

 suffer very seriously from them sometimes, for wounds from thorns 

 are dangerous things in a climate where even a scratch is liable to 

 produce gangrene.
