From these points it is possible to suggest that the short-rayed plants are established hybrids of 

 A. homogamos x radiatus and A. homogamos xclavatus. Observations on habit and cypsela 

 morphology support this interpretation, particularly in the variation of overall plant size, cypsela 

 size, wing structure and auricle shape. 



A. homogamos was not previously unrecognized but was considered to be only a variety of 

 A, valentinus L. A new name had to be found for the homogamous plants, as Linnaeus's type for 

 A. valentinus is a Spanish specimen of one of the hybrids A. homogamos X radiatus (see p. 109).
