multiplication. The derived polyploid species may blend the 
morphological traits of two or more of their parental taxa, often 
making it difficult to assign species names to particular popula¬ 
tions. The taxonomy of hybrid complexes is often handled dif¬ 
ferently by different authors, and in our comments in the Check¬ 
list, we usually indicate whose opinions we are following in par¬ 
ticular genera. In Oregon there are excellent examples of polyp¬ 
loid complexes in Agoseris, Antennaria, Arnica, Artemisia, Aster, 
Crepis, Ericameria, Eriophyllum, and Pyrrocoma. When polyp¬ 
loidy is combined with asexual propagation, as for example in 
Antennaria, Arnica, and Crepis, it becomes nearly impossible, in 
many cases, to draw sharp distinctions between the species. 
The Asteraceae Checklist is the first of many such lists of 
Oregon plants to be distributed by the Oregon Flora Project.
