Taxonomy

The species was first described, as Chrysosplenium flagelliferum var. tosaense, by Japanese botanist Makino Tomitarō in 1901 (his 1892 mention of Chrysosplenium tosaense is a nomen nudum).^[1]^[2]^[4] In 1935, Sutō Chiharu elevated the variety to species rank.^[2] The specific epithet relates to the type locality, Nanokawa in Kōchi Prefecture (formerly Tosa Province).^[1]

Chrysosplenium tosaense grows to a height of 5–17 centimetres (2.0–6.7 in) and flowers from April to May.^[1]

Chrysosplenium tosaense is endemic to Japan, where it occurs from the Kantō region to the Chūgoku region of Honshū, Shikoku, and Kyūshū.^[2]^[3]
