Beech and the species "F. okamotoi", proposed by the botanist Chung-Fu Shen in 1992, comprise this subgenus. The better known "Fagus" subgenus beeches are high-branching with tall, stout trunks and smooth silver-grey bark. This group includes "Fagus sylvatica", "Fagus grandifolia", "Fagus crenata", "Fagus lucida", "Fagus longipetiolata", and "Fagus hayatae". The classification of the European beech, "Fagus sylvatica" is complex, with a variety of different names proposed for different species and subspecies within this region (for example "Fagus taurica", "Fagus orientalis", and "Fagus moesica"). Research suggests that beeches in Eurasia differentiated fairly late in evolutionary history, during the Miocene. The populations in
Luzula sylvatica Luzula sylvatica Luzula sylvatica, commonly known as greater wood-rush or great wood-rush, is a perennial flowering plant in the rush family Juncaceae. With regards to the etymology of the binomial, "Luzula" could come from the Italian "lucciola" ("to shine, sparkle") or the Latin "luzulae" or "luxulae", from "lux" ("light"), inspired by the way the plants sparkle when wet with dew; whilst "sylvatica" comes from silva, Latin for forest.
