A correspondent of W.J. Hooker, Charles Millett was resident in Macau from about 1827 as an official at the East India Company's factory there. He collected plants in this area and later while stationed in Ceylon and Malabar. In 1831 he travelled to Java, where he employed locals to help him collect. Millett left Asia on the disbandment of the Company's Factory in 1834 and returned to London, where he married Anne Crohan.
