Rohdea Explained

Rohdea is a genus of plants native to eastern Asia (China, Japan, the Himalayas and Indochina).^[1] It was long thought to contain only a single species, R. japonica,^[2] but recent studies have resulted in several other taxa being transferred into the genus.^{[3] [4]}

In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). It has also been placed in the former family Convallariaceae.

Although sometimes misspelled as Rhodea, the genus was actually named after Michael Rohde (1782-1812), a botanist from Bremen.^[5]
