Elaphoglossum serpens is a rare species of fern that grows only on Cerro de Punta, the highest mountain in Puerto Rico.

This fern is an epiphyte which grows on the trunks of the tree species Lyonia rubiginosa var.

[1] The fern grows on mossy tree trunks in the elfin forest on the highest peak on the island of Puerto Rico.

[1] Because this plant is known from only one location, habitat destruction or disturbance in that area could result in the extinction of the species.

[1] Many permits have been requested by entities interested in building structures in the area, an activity that has caused plant destruction in the past.
