Taxonomy
1 Potamogeton wrightii is the most frequent species of the genus in Malesia. It is highly polymorphic forming several local variants. The most aberrant ones are the following:
- a) from Papua New Guinea: Leach 7805 (UPNG). It unites characters of P. wrightii, P. lucens, and P. papuanicus and may also be regarded as a hybrid or as a species in its own right;
- b) from Mindoro: Britton 277 (L). A broad-leaved form with undulate margins and asymmetric leaf ground.
