Shrubs or trees, to 20(-45) m. Bark gray or brown, smooth or deeply furrowed. Twigs densely yellowish tomentose. Leaf blade adaxially convex, to 60-120 mm, leathery to brittle, margins often revolute, regularly toothed, teeth prominent to obscure; surfaces abaxially prominently and densely woolly, often glabrate at maturity, revealing gray or bluish green waxy surface, veins often distally impressed. Fruits: cup scales subulate, spreading to strongly recurved, hooked; nut yellowish brown, globose to cylindric-tapered, to 15-35 mm, extremely hard, densely tomentose, eventually glabrate.
Distribution
Only in the flora.
Discussion
Varieties 2: only in the flora.
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).
