CONYZA. 297 
2. The characters of Jussieu and Sprengel are both er- 
roneous, although J'ussieu's is far the best, as there is only 
one scale which does not separate with each capitulum, aud 
as it is inferior to each, it is certainly a bractea, and belongs 
to the axis of inflorescence. All the rest are referable to the 
capitula. There is no common involucrum, at least more. 
than resulting from the outermost bractea. 
3. It is entirely a Corymbifera, its peculiarity being the 
aggregation of its capitula.
