Japanese pepper - Japanese pepper

Japanese: サンショウソウ - さんしょうそう

A perennial plant of the Urticaceae family that grows in the valleys of evergreen broad-leaved forests (illustration). The leaves are lined on both sides of the stem that creeps along the ground surface, and resemble the compound leaves of the Japanese pepper plant, hence the Japanese name. The stem branches and grows to cover the ground surface, 10-30 cm long, with short, spreading hairs that stand out. The leaves are small, 0.4-1.5 cm long. The closely related giant salamander P. radicans (Sieb.et Zucc.) Wedd. has larger leaves, 2-4.5 cm long, and the hairs on the stem are very short and inconspicuous.

照葉樹林帯の谷間に生えるイラクサ科の多年草（イラスト）。葉は地表面をはう茎の両側に並び，そのようすがサンショウの複葉に似ていることから和名がついた。茎は分枝して地表面をおおうように伸び，長さ10～30cm，開出する短毛があってよく目だつ。葉は長さ0.4～1.5cmと小型。近縁のオオサンショウソウP.radicans (Sieb.et Zucc.) Wedd.は葉がより大型で，長さ2～4.5cm，茎の毛はごく短く目だたない。
