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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
