Field work in Peninsular Malaysia as part of the first author's research into relationships and evolutionary polarity between Hanguana malayana, a widespread freshwater helophyte, and the numerous and mostly undescribed Sundaic forest species has to date resulted in the collection of five distinctive novel forest-dwelling Hanguana species. These are described here and figured in colour. Increased understanding of these and other forest species of Hanguana has enabled a concise delimitation of the taxonomically long-obfuscated colonial helophytic H. malayana, and this is here presented, and the species figured. The current taxonomy of Hanguana is summarised, and a key to the so-far described Peninsular Malaysian species is provided.
