Burchell travelled in Africa between 1810 and 1815, collecting over 50,000 specimens. He described his journey in Travels in the interior of southern Africa (1822-4). He travelled in Brazil between 1825 and 1830, again collecting a large number of specimens, including over 20,000 insects.
A large part of Burchell's collection was presented to the Oxford University Museum after his death.
Burchell, who never married after that experience, left for Cape Town in 1810.
Burchell spent the next decade back in Fulham, arranging his specimens and writing up his results.
During his time at Fulham many enthusiasts visited Burchell to see his collections, and one of those who saw "Burchell's Clivia" was instrumental in locating and importing living specimens to Britain, some time in the 1820's.
