Shrubs, rhizomatous, much branched, to 4 m; young growth minutely pilosulous. Petioles (5–)10(–19) mm. Leaf blades ovate-oblong, obovate, or elliptic, (4.2–)10(–21) × (2–)4(–8) cm, base acute to rounded, apex acute to acuminate, surfaces puberulent when young.

Discussion
Pyrularia pubera can be locally abundant in the Blue Ridge Mountains and Appalachian Plateau, often forming dense stands in second-growth forests. The species is apparently a host generalist (D. J. Leopold and R. N. Muller 1983) and has been reported to parasitize planted fir trees (Abies fraseri) in Virginia (L. J. Musselman and S. C. Haynes 1996). The seeds are very high in oil. Cytotoxic and antimicrobial peptides called thionins are present in P. pubera (L. P. Vernon et al. 1985).
