Discussion

Pseudognaphalium luteoalbum is native to Eurasia. It is similar in overall habit to P. stramineum but distinctive in its larger heads and red-tipped corollas (visible through the translucent phyllaries). Cypselae of P. luteoalbum have papilliform hairs; cypselae of other North American species of Pseudognaphalium are glabrous.
