blades (crowded, internodes 1–5, sometimes to 10 mm) narrowly obovate to subspatulate, 1–3(–6) cm × 2–8 mm (distal smaller, oblanceolate to narrowly oblong or linear), bases subclasping, usually decurrent 1–2 mm, margins weakly revolute, faces mostly concolor to weakly bicolor, abaxial gray-tomentose, adaxial usually gray-tomentose, sometimes glabrescent, neither glandular.
blades narrowly lanceolate to nearly linear, 3–10 cm × 3–6 mm, bases not clasping, decurrent 4–8 mm, margins flat or slightly revolute, faces concolor, tomentose-sericeous (bases of hairs enlarged), sessile-glandular beneath tomentum.

Pseudognaphalium luteoalbum
Pseudognaphalium jaliscense
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.

Pseudognaphalium jaliscense is recognized by its relatively long, narrow, concolor to weakly bicolor leaves with non-clasping, short-decurrent bases, relatively large heads with white, opaque, dull phyllaries, and relatively large numbers of pistillate and bisexual florets. Counts of pistillate and bisexual florets from the United States collections are mostly 90–115 and (6–)8–12 (fewer than in Mexico).
