Hiroyoshi Ohashi

is a botanist formerly at the University of Tokyo and Tohoku University. He began publishing on Japanese ''Arisaema'' in the early 1960s. He published a couple of miscellaneous notes on ''Arisaema'' in 1963 and 1964 and these were followed by a revision of the genus for Japan jointly published in 1980 with J. Murata, and by the Araceae treatment for the Wildflowers of Japan (Ohashi, 1982).

He continued the work of the noted botanist Hara on the ''Flora of Eastern Himalaya''. He has also compiled a list of types of ''Arisaema'' in Japanese herbaria and studied pollen morphology of Japanese ''Arisaema'' (Ohashi et al., 1983). Provided by Wikipedia
