Nesaea pedicellata

Nesaea pedicellata is a synonym of Ammannia pedicellata; since 2013 all Nesaea species have been placed in Ammannia.²³ This East African marsh plant is recorded from Tanzania including Mafia and Zanzibar and from Mozambique, and according to POWO also from south-eastern Kenya.²³⁴ At swamp margins and in pools it reaches up to 50 cm; its stems are green to dark red.²

This large-growing species suits the midground or background of tanks from about 190 l.⁴ CO₂ is not essential but makes it bushier; it should be fertilised regularly, as it recovers only slowly from deficiencies, especially of nitrogen.⁴ The shoots are planted with spacing so that light also reaches the lower parts; kept too dark, they stay small and the lower leaves turn blackish.²
