Sterile specimens of Lithocarpus densiflorus
are often confused with Chrysolepis
and vice versa. Nonfruiting material of L . densiflorus is recognizable by the loose tomentose pubescence of the leaves and inflorescences (although the leaves are often glabrate with age). Chrysolepis
lacks this tomentose pubescence and has only a tight vestiture of glandular-peltate trichomes, except for some stellate and straight simple trichomes associated with the flowers.
The Costanoan used infusions prepared from the bark of Lithocarpus densiflora (no varieties specified) as a wash for facial sores and to tighten loose teeth (D. E. Moerman 1986).
