Abstract

Taraxacum pseudohamatum is reported from Rēkohu / Wharekauri / Chatham Island in the Chatham Islands, Aotearoa / New Zealand. This species is an addition to that island group’s naturalised flora and the New Zealand Botanical Region. It is also the second member of Taraxacum Sect. Hamatum to be recorded from the islands. The first species of that section to be recorded from the islands is Taraxacum hamatum, which is still only known from a collection made from Hokorereoro / Rangatira / South East Island. Taraxacum pseudohamatum is locally common on Rēkohu / Wharekauri / Chatham Island. The species is described using material from that island, and notes on its recognition and distinction from T. hamatum presented. The ecology of the species on Rēkohu / Wharekauri / Chatham Island is described.
