Trained as a horticulturalist in Germany, Betche arrived in Sydney in 1881 and almost immediately was appointed collector for the Sydney Botanic Gardens, New South Wales. Promoted to Botanic Assistant (to Maiden) from 1897. With C.Moore he wrote The Handbook of the Flora of New South Wales (1893) and with J.H.Maiden, Census of New South Wales Plants (1916), published after his death. He cooperated with Maiden on various short notes on the flora of New South Wales, and himself published on Goodeniaceae. His herbarium is to be found in NSW.
