Mills (active 1836~1842) was also the main illustrator for Knowles and Westcotts The Floral Cabinet (1837-1842). Benjamin Maund's The Botanist was a five-volume series that introduced 250 new plants from 1836 to 1842. The series is notable for its many female artists: the plates were drawn by Maund's daughters Sarah and Eliza, Augusta Withers, Priscilla Bury, Jane Taylor, Miss R. Mills among others.
