Asplenium dissectum

A finely divided spleenwort of Neotropical montane forest, from Mexico and the Greater Antilles to Colombia, Ecuador and northern Brazil. Most records come from 1400–1900 m in Costa Rica and Colombia, so it wants mild temperatures, high humidity and shade.

Where it grows wild

Montane wet and cloud forest; Colombian herbarium data list it as an herb at 800–2700 m in the Andes, Sierra Nevada de Santa Marta, Macarena and Pacific slope. It is treated here as a shade fern of mossy trunks and banks.

Recorded at 0–2722 m, median 1650 m (201 records); Colombian data give 800–2700 m.
