Bolbitis humblotii

A Madagascan Bolbitis recorded mostly in the humid lowland and lower montane rainforest of the north-east, from near sea level to about 900 m. Like its relatives it is best treated as a shade fern of wet, rocky stream margins: warm, constantly humid and never allowed to dry out. Little is published on this species, so the care below leans on the genus.

Where it grows wild

Recorded in the evergreen rainforest belt of north-eastern Madagascar. Bolbitis species typically creep over wet rocks and soil along shaded streams, sometimes in the splash zone; species-specific habitat notes were not found.

Records span 10–920 m, median about 420 m, so it is a lowland to lower-montane plant.
