Thelypteris yaucoensis is a rare species of fern known by the common name Puerto Rico maiden fern.[1] It is endemic to Puerto Rico, where it is known from only three localities. It is a federally listed endangered species of the United States.
This fern was placed on the endangered species list in 1993. At that time it was known to exist at three locations: two in Yauco and one in Ciales in Puerto Rico. There are a total of about 65 plants known at all three combined.[2]
This terrestrial fern has fronds up to 52 centimeters long with the blades divided into 13 to 15 pairs of segments.[2]
