Blechnum binervatum

A climbing fern of humid montane forest in the Lesser Antilles and the northern Andes, whose creeping rhizome scrambles up tree trunks and carries separate sterile and narrow fertile fronds (often placed in Lomaridium). It wants steady mild temperatures, shade, constant moisture and very humid air.
