The aquarium plant later identified as Hyptis lorentziana was introduced from the vicinity of Manaus (Brazil) under the fantasy name “Hemigraphis traian”. Another trade name for H. lorentziana is “Hemigraphis sp. from Manaus”.
Hyptis lorentziana does bear some resemblance to some Hemigraphis species, but belongs to the mint family (Lamiaceae). Hemigraphis species, by contrast, belong to the acanthus family (Acanthaceae), as do Hygrophila and Staurogyne.
