Aceriphyllum rosii Engler

Japanese: イワヤツデ（英語表記）Aceriphyllum rosii Engler

A perennial plant of the Saxifragaceae family, with only one species in the genus, native to the Korean Peninsula and northeastern China, which is often cultivated in Japan for decorative purposes (illustration). It is also called Tancho-sou. It is deciduous, with a thick horizontal rhizome from which new leaves and flower stalks emerge every spring. The leaves have long stalks measuring 20-30 cm, and are hairless, along with the blades. The leaf blades are deeply palmately lobed like maples and fatsias, green on the upper side and pale green on the underside, with prominent veins. In early spring, it produces many white flowers in cymes, the branches of which initially curl outwards.

朝鮮半島や中国東北に自生する1属1種のユキノシタ科の多年草で，日本ではしばしば観賞用として栽培される（イラスト）。タンチョウソウともいう。落葉性で，横にはった太い根茎があって，毎春，そこから新しい葉と花茎を出す。葉には20～30cmの長い柄があり，葉身とともに毛はない。葉身は，カエデやヤツデのように掌状に深く裂け，表は緑色，裏は淡緑色で，浮き出た脈が目立つ。春先に集散状の花序に多くの白い花をつけるが，花序の枝は，初め外側に巻いている。
