Discussion

Pseudognaphalium macounii is recognized by its stipitate-glandular, proximally glabrescent stems, bicolor and decurrent leaves, relatively large and many-flowered heads, and hyaline, shiny phyllaries. Reports of P. macounii from Texas are based on specimens of P. viscosum.

Leaf insertion in Pseudognaphalium californicum is unusually variable: bases may be clasping to subclasping without decurrent margins or decurrent and not show any clasping tendency.
