This seminal publication began life as a collaborative effort between the Irish botanist William Henry Harvey 1811-66 and his German counterpart Otto Wilhelm Sonder 1812-81. Relying on many contributors of specimens and descriptions from colonial South Africa - and building on the foundations laid by Carl Peter Thunberg, whose Flora Capensis 1823 is also reissued in this series - they published the first three volumes between 1860 and 1865. These were reprinted unchanged in 1894, and from 1896 the project was supervised by William Thiselton-Dyer 1843-1928, director of the Royal Botanic Gardens at Kew. A final supplement appeared in 1933. Reissued now in ten parts, this significant reference work catalogues more than 11,500 species of plant found in South Africa. Volume 4 appeared in two parts, the first comprising sections published between 1905 and 1909, covering Vacciniaceae to Gentianeae.
