Abstract:

A checklist of 97 rare flowering plant species are presented. 30 species have been selected for recommendation for inclusion on the Red List of Tonga plants produced by the IUCN. These are discussed in more detail, arranged in the following categories: Tongan endemics, represented by six species; indigenous non-orchid species, represented by 19 species; and indigenous orchid species, represented by five species. Additionally, eight non-native species have also be selected for recommended for inclusion on the Red List. These species should also be considered for some kind of status, since these are either ancient Polynesian weeds possibly threatened over their entire range, or traditional cultigens possibly threatened over their entire range. They are divided into Polynesian adventives, represented by three species; and Polynesian cultigens, represented by five species. For details on the 30 recommended species, see their complete descriptions in the species profiles.
