Rotala macrandra 'Butterfly'

Rotala macrandra 'Butterfly' (also 'Mini Type V') is a small-leaved selection of the variable southern Indian species R. macrandra (Lythraceae).¹²³ Upright, densely leaved shoots bear narrow, slightly wavy leaves that turn out somewhat larger than in 'Mini' and colour an intense red under strong light.¹ Forum reports describe the shade partly as magenta, partly as wine red.³

It is considered demanding; CO₂ addition, regular complete fertilisation, low carbonate hardness and fairly strong light are recommended.¹ Keepers report slow acclimatisation and new growth that stays green or reverts to the green parent form.³⁴ It is planted in groups in the midground and, owing to its small leaves, also in nano aquariums.¹
