186 Mr. D. Don’s Descriptions of new Genera and Species 
place of the Cichoracee of the Northern hemisphere, to whom 
they bear a striking analogy both in habit and structure; but in 
the Chilian Flora, where this family is more especially abundant, 
they form nearly one-half of the whole class. 1 have ventured 
to give the descriptions of a few interesting species from Brazil 
belonging to this family, whose affinities seemed to justify their 
insertion in this memoir.
