length of their slender petioles ; those of the branches similar, but smaller. There 

 are often a few glands on the face of the leaf, as well as at the obscure repand 

 crenatures. Peduncles, heads, &c. as described by De Candolle ; except that the 

 involucre is not quite an inch long, and its scales are scarcely if at all apiculate or 

 mucronate. Achenia pubescent. — This is more closely allied to P. ruderale (which 

 often has pellucid glands on the leaves) than to P. ellipticum.
