Hong Kong croton (Croton hancei)
Description
Croton hancei Benth., the Hong Kong croton, is a shrub or small tree, a species of Croton which is endemic to Tsing Yi Island, Hong Kong. In Hong Kong, it is listed in the book Rare and precious Plants of Hong Kong. Croton hancei was discovered by H. F. Hance on Hong Kong Island in the 1850s and published by botanist George Bentham as a new species in Flora Hongkongensis in 1861. The species was not observed again until 21 February 1997, when staff of the Hong Kong Herbarium of the Agriculture, Fisheries and Conservation Department found an "unknown" species on a steep slope woodland under the highest peak, Tsing Yi Peak, on Tsing Yi Island. After confirmation by experts from the South China Institute of Botany, the Hong Kong Croton was re-discovered after a gap of over a century. The woodland measuring 1.05 hectares (2.6 acres) is considered to be a Site of Special Scientific Interest (SSSI) for the protection of the endemic Hong Kong croton.
