Arisaema ringens tuber
Pen and ink on Bristol board, unframed
An original pen and ink illustration of an Arisaema ringens tuber.
Japanese common name: Musashi-abumi. Abumi are early Japanese stirrups, Miyamoto Musashi (c. 1584 – June 13, 1645) was an expert Japanese swordsman and rōnin. My conjecture is that the common name may mean Mushahi’s stirrups. The abumi are very similar in shape to the hooded spathe of A. ringens.

A. ringens is quite unique amongst Pistillata, in that it has a galeate inflorescence (helmet shaped/hooded), a simple eophyll (first leaf) and a creamy white receptacle. The galeate inflorescence is similar to A. galeatum, in the Arisaema section, however the shape of the spadix appendage shows its relation within Pistillata. It is popularly cultivated because of its great foliage and fantastic inflorescence, but it seldom produces ripe fruits, probably due to lack of a good pollinator outside of its natural environment.
Deciduous, to 110cm tall and 80cm wide, distribution through Japan; Honshu, Shikoku, Kyushu and Ryukyu, S Korea, China; Taiwan, Jiangsu and Zhejiang. Woodland clearings in leafy soil at low altitude near the seacoast. Flowering period March to May, ripening November.
