[1][4][5] Most of the plates in the book are by Sowerby, starting with Plate 10,[6] and range from clematis, dianthus, petunia, and calceolaria to the Australian wildflower Sturt's desert pea (Swainsona formosa, formerly Clianthus dampieri).
[1] Although most of Sowerby's known works are botanical illustrations, there is extant an 1854 watercolor by her of a quartz crystal with asbestos inclusions, apparently drawn from a specimen in her family's collection.
[8] There are also three drawings of volcanoes made for George Julius Poulett Scrope.
[8] She is buried in a family grave on the west side of Highgate Cemetery with her father George Brettingham Sowerby I and brother George Brettingham Sowerby II.
In 1997, a detail of Sowerby's watercolor of Guzmania splendens was included in a British stamp issue.
