List of Quercus species

The genus Quercus (oak) contains over 500 species,^[1] some of which are listed here.

The genus, as is the case with many large genera, is divided into subgenera and sections (see Taxonomic ranks in botany).

Use of # in this list[]

Species with evergreen foliage ("live oaks") are tagged #. Note that the change from the deciduous to the evergreen term (or vice versa) has happened on numerous occasions in the genus Quercus, and does not necessarily indicate that the species concerned are closely related.

Subgenus Cyclobalanopsis[]

Illustration of Quercus lamellosa, showing acorns in clusters, with visible rings on their cups

The ring-cupped oaks (synonym genus Cyclobalanopsis). Eastern and southeastern Asia. They are distinct from subgenus Quercus in that they have acorns with distinctive cups bearing concrescent rings of scales; they commonly also have densely clustered acorns, though this does not apply to all of the species. About 150 species.
