Notes

Isaac Louis Drège was born in Paarl, the son of Carl Friedrich Drège, a German apothecary, naturalist and traveller who travelled extensively into various parts of South Africa with his brother, Franz, collecting plants and zoological and ethnological specimens.  He trained as an apothecary and settled in Port Elizabeth, collecting plants in the Albany, Uitenhage and Port Elizabeth districts, particularly at Aloes, north of Port Elizabeth.  He published 'A preliminary list of flowering plants, ferns and fern allies found in the Port Elizabeth District' in South African Journal of Science, 1912: pp. 151-175 (1913).   He corresponded with Schonland and Burtt Davy and sent living plants to Kew in the United Kingdom. Volumes I and II were donated to the Royal Botanical Gardens, Kew, UK, in 2002
