  Title: Adiantum viridimontanum
  Passage: Adiantum viridimontanum, commonly known as Green Mountain maidenhair fern, is a rare fern found only in outcrops of serpentine rock in New England and Eastern Canada.  The leaf blade is cut into finger-like segments, themselves once-divided, which are borne on the outer side of a curved, dark, glossy rachis (the central stalk of the leaf).  These finger-like segments are not individual leaves, but parts of a single compound leaf.  The "fingers" may be drooping or erect, depending on whether the individual fern grows in shade or sunlight.  Spores are borne under false indusia (rolled flaps of tissue) at the edge of the subdivisions of the leaf, a characteristic unique to the genus "Adiantum".
