Species Bowkeria gerrardiana

For James Henry Bowker (1822–1900), South African naturalist and army colonel who took part in the seventh and eighth Cape Frontier Wars (1846–1853). He became an authority on butterflies collected in the Eastern Cape and elsewhere (including plants) together with his artist sister, Mary Elizabeth Barber née Bowker (1818–1899), a noted botanist and entomologist who corresponded regularly with Joseph and William Hooker at the Royal Botanic Gardens, Kew, and Charles Darwin. She sent many plant specimens, many previously unknown, to the herbarium of Trinity College, Dublin and Kew Gardens. She authored scientific papers on botany and entomology and general articles in many fields, including stone-age implements. The Bowkeria name commemorates them both.
