| Botanist and explorer, born in Grossenhain, Saxony. He went to the USA in 1799, and managed a botanical garden near Philadelphia (1802–5). He undertook two botanical explorations of the territory from North Carolina to Vermont (1806, 1807). In 1814 he published Flora Americae Septentrionalis, which included many new species discovered by Lewis and Clark and was the most complete account to that time of the flora of the USA. |
