 — Within the tide of La Plata. Tweedie, {in Herb. Am.) — 

 The style has no appendage or cone ; but its pubescence is 

 not manifestly longer than the apex, as in the true species of 

 the genus. The external appearance of the style is thus 

 more of the Asleroidece than of the SenecionidecB ; but the 

 stigmatic lines reach to about the apex, and therefore much 

 beyond the commencement of the pubescence.
