base, on petioles two lines long. Stems, as De Candolle 

 well observes, apparently climbing, so as, in conjunction with 

 the form of the petiolated leaves, to give the appearance of 

 0. Clematis. Capitula small. Scales of the involucre slightly 

 eroso-ciliate at the margin, with a dark green nerve down the 

 middle. Pappus of the male flowers rufous.

Rio grande do Sul. Isabelle. — This seems very different from 

 any described species. The pappus of the female plant is 

 tawny, longer than the styles, twice as long as the involucre.

 Tweedie — De Candolle places this very well-marked plant 



in the first division, but in the cuneate leaves it accords well 

 with the present section, though it must be confessed it has 

 little natural affinity with the following species. The rough 

 coarsely toothed leaves, with the very prominent nerves on 

 the under-side, give the plant a great resemblance to some 

 N. American species of Verbena.
