sawtooth oak (クヌギ) #7532

Quercus acutissima, the Sawtooth Oak, is an oak originally native to eastern Asia, in China, Korea and Japan. It is now also present in North America. It is closely related to the Turkey Oak, classified with it in Quercus sect. Cerris, a section of the genus characterised by shoot buds surrounded by soft bristles, bristle-tipped leaf lobes, and acorns that mature in about 18 months.

An oak is a tree or shrub in the genus Quercus ( /ˈkwɜrkəs/; Latin "oak tree"), of which about 600 species exist. "Oak" may also appear in the names of species in related genera, notably Lithocarpus. The genus is native to the northern hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in Asia and the Americas.
