The 2012 edition of Check List of Hong Kong Plants was compiled on the basis of the Flora of Hong Kong and other relevant taxonomical information, and recorded 3329 plant species and varieties.

Besides the addition of new records and amendments, this edition also provides a reference list for tracing the scientific names recorded in the last edition but not in this one owing to new taxonomical findings or nomenclatural amendments. In addition, a section of colour plates displaying some examples of newly recorded plants has been included.
