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.) |
Pseudognaphalium microcephalum is characterized by stems commonly stiffly erect and slightly zigzag distally, relatively thick (3–5 mm diam. near bases), and closely grayish tomentose, leaves oblanceolate, sessile, sometimes clasping, not decurrent, and weakly bicolor, and heads usually in open, corymbiform arrays.
