Asplenium buettneri

Asplenium buettneri is a small, finely divided spleenwort that is widespread in tropical Africa, from Guinea to Ethiopia and south to Mozambique and Madagascar. One herbarium label describes it as a lithophyte up to 30 cm tall with a creeping rhizome and 3–4-pinnate fronds, growing on rock in forest. Grow it as a warm, shaded, humid rock fern.

Where it grows wild

Forest from lowland to submontane zones. One specimen label calls it a lithophytic herb growing on rock. Other labels only name forest reserves and river valleys, so the microhabitat is inferred from that note and from the genus.

The records range from 300 m to 4386 m, with a median of 1200 m. The top value is probably a georeferencing error, and most plants grow between about 600 and 1500 m.
