Nomenclature Note:
“Quercus annulata was described from specimens collected by Scottish physician Francis Buchanan-Hamilton in Nepal. Smith (1814) described it as: ‘Leaves evergreen, rigid, exactly like those of [Q. glauca], but somewhat silky beneath, and less glaucous, the young ones very silky.’ Quercus glauca is variable in the colour of the leaf underside and the leaves can be silky when young. Smith continues: ‘We find great reason to think that it may be, as Dr. Buchanan suspected, the same species with Thunberg’s glauca.” (cf. Trees & Shrubs Online Taxonomic Note)
Further, ongoing molecular work supports the synonymization of this name (Min Deng, pers. comm.)
