The Hu Card Index is a file of 158,844 cards for Chinese plant names (1753-1955) which was produced by Dr. Hu Shiu-ying (Arnold Arboretum of Harvard University). A web interface is available for browsing and searching the cards. Because infraspecific names and their places of publication are difficult to find (e.g., the Index Kewensis did not begin recording these until 1971), the following ca. 9000 infraspecific names were extracted from the Hu Card Index, and listed here so that they can be more easily located via web searches. Please note that these have not been standardized or verified at this time. Literature and specimen citations were added to a separate file. It is hoped that these will eventually be indexed by IPNI and Tropicos, and linked to images of types, etc.
