An English gardener who visited Australia collecting seeds and plants for British nurserymen. Collected on Kangaroo Island, South Australia (1822-1823), and possibly again in South Australia along the south coast in 1829. Later he collected along the southern coast of Western Australia (1823-1825, 1828-1829) at King George Sound, Cape Arid and Lucky Bay for nurserymen and private individuals. He also collected at Twofold Bay, New South Wales, and at Wilsons Promontory, Victoria (1826). His last expedition in 1828-1829 to Western Australia was arranged by Charles Fraser, in part to collect material for the Sydney Botanic Gardens, New South Wales, but the two disagreed over division of the material on his return. His collections are housed at BM and K, with a few duplicates at CGE, DBN, FI, MO and NY.
