Blechnum fuscosquamosum

A high-elevation Andean and Central American fern from Costa Rica, Colombia and Bolivia, recorded mostly around 2,600–3,000 m. It is a cool, wet montane plant: steady mild days, chilly nights and rain most of the year. Little is published beyond the description, so conditions here come from the measured sites and from montane Blechnum in general.

Where it grows wild

Montane and upper montane cloud forest, probably in forest openings, edges and banks as is usual for terrestrial montane Blechnum. Habitat detail for this species is thin.

Recorded 225–3000 m, but the median is about 2,700 m; the lowest records look like georeferencing errors.
