Fruit and foliage of a dwarf variety of Buxus microphylla (Hohman's Dwarf)

Buxus microphylla (Japanese Box or Littleleaf Box) is a species of Buxus native to Japan and Taiwan.[1]

It is an evergreen shrub or small tree growing to 2–3 m tall. The leaves are bright green, 10–25 mm long, oval with a rounded or notched tip.[2][3]

The species was first described from Japanese cultivated plants of an unknown origin; these are dwarf shrubs that only grow to a height of 1 m, possessing small leaves less than 18 mm long. Wild box plants in Japan differ somewhat, growing to be 2–3 m tall with leaves up to 25 mm long; they are sometimes distinguished as Buxus microphylla var. japonica (Muell.-Arg.) Rehder & Wilson (syn. B. japonica Muell.-Arg.).[1][3]

Plants from Taiwan are distinguished as Buxus microphylla var. tarokoensis S.Y.Lu & Y.P.Yang.[4]

Plants from China and Korea formerly often cited as Buxus microphylla var. sinica are now treated as a distinct species Buxus sinica.[5]

The species is grown as an ornamental plant, both in its native area and elsewhere in temperate regions around the world.[6]

Buxus microphylla var. compacta (Kingsville Dwarf Boxwood) and similar cultivars are frequently used for bonsai.
