Cinnamomum camphora Presl var.nominale Hayata subvar.hosyo Hatusima

Japanese: ホウショウ(芳樟) - ホウショウ（英語表記）Cinnamomum camphora Presl var.nominale Hayata subvar.hosyo Hatusima

A tall tree of the Lauraceae family. A subvariety of camphor, it is found from southern China to southeastern Taiwan. Its flowers and fruits are smaller than those of camphor, and it differs in that its leaf edges are wavy. The basic camphor species contains camphor in the plant body, but camphor contains almost no camphor, and instead contains 1.5 times as much linalool as camphor. Steam distillation of the branches and leaves produces about 1% essential oil, of which 30-70% is linalool. The essential oil has a refined fragrance and is used in high-end perfumes.

Japanese:

クスノキ科の高木。クスノキの亜変種で，中国南部から台湾南東部に分布する。クスノキに比べて花も果実も小ぶりで，葉縁が波打つ点で異なる。また基本種のクスノキは，植物体にショウノウ(樟脳)を含むが，ホウショウではショウノウはほとんど含まず，その代りリナロールをクスノキの1.5倍含有する。枝葉を水蒸気蒸留すると約1％の精油が得られるが，この精油の中の30～70％がリナロールである。精油は品のよい香りで，高級な香料に使われる。
