Coloured engravings of heaths; vol. 3

"Coloured Engravings of Heaths; Vol. 3" by Henry Cranke Andrews is a comprehensive early 19th-century scientific work with detailed color illustrations. It catalogs various heath species, especially those from the Cape of Good Hope. The writing contains botanical information, like flowering times and where they live. The author aims to document the growth of heath types since his first book. Andrews mentions how many species grow successfully from seeds, which was a change from what people thought at the time. Also, he plans a fourth book with all heath types now known, including pictures of seeds to complete the work. The book then organizes Erica species, pointing to the author's care in classifying them.
