Bearhorn - Bearhorn

Japanese: クマシデ - くましで
Bearhorn - Bearhorn

A deciduous tall tree of the Betulaceae family (APG classification: Betulaceae). It grows to a height of about 12 meters, but some can reach over 20 meters. The bark of old trees is dark brown and shallowly fissured. The leaves are narrowly ovate, 6-11 cm long, and have 20-24 pairs of lateral veins. The number of lateral veins is greater than in other hornbeam species. It is monoecious and blooms at the same time as the buds open in May. In autumn, large cylindrical fruit spikes hang down. The bracts of the spikes are densely packed and contain nuts at the base. It is commonly found in mountainous broadleaf forests, and is distributed in Honshu, Shikoku, and Kyushu west of Iwate Prefecture. The wood is hard and is used for toys, agricultural tool handles, charcoal, and shiitake mushroom logs. It is said to have been named after the carpinus arborescens because it is more magnificent overall than the carpinus arborescens.

カバノキ科(APG分類:カバノキ科)の落葉高木。高さ12メートルくらいであるが、20メートル以上になるものもある。老木の樹皮は黒褐色で浅く割れる。葉は狭卵形で長さ6~11センチメートル、20~24対の側脈がある。ほかのシデ類より葉の側脈数が多い。雌雄同株で、5月ころ芽が開くと同時に開花する。秋には大形の円柱状の果穂が垂れ下がる。果穂の包葉は密につき、基部には堅果を抱く。山地の広葉樹林内に普通にみられ、岩手県以西の本州、四国、九州に分布する。材は堅く、玩具(がんぐ)、農具の柄(え)、炭、シイタケ原木などに用いる。イヌシデより全体がより壮大なのでこの名があるといわれる。
