Adiantum viridimontanum, commonly known as Green Mountain maidenhair
fern, is a rare fern found only in outcrops of serpentine rock in New
England and Canada. It is named after the site of its discovery in the
Green Mountains in Vermont; it has since been located in Quebec and in
one site on serpentine in coastal Maine. Until 1991, it was grouped with
the western maidenhair fern A. aleuticum, which itself was classified
as a variety of the northern maidenhair fern A. pedatum. It was then
established that A. viridimontanum was a hybrid species and that the
other two ferns were distinct species, although it is difficult to
distinguish between the three species in the field. Due to the limited
distribution of A. viridimontanum and its similarity to other species,
little is known of its ecology. It thrives on sunny, disturbed areas
where ultramafic rock is covered with thin soil, such as road cuts,
talus slopes, and asbestos mines. Individual plants seem long-lived, and
new individuals only infrequently reach maturity. It is one of four
species endemic to serpentine in eastern North America and is considered
globally threatened due to its habitat restrictions.

Wikiquote quote of the day:
Truth has no path. Truth is living and, therefore, changing.
Awareness is without choice, without demand, without anxiety; in that
state of mind, there is perception. To know oneself is to study oneself
in action with another person. Awareness has no frontier; it is giving
of your whole being, without exclusion.
