Species: Botrychium minganense
Encyclopedia of Puget Sound
Mingan Island Moonwort is a small perennial fern with a single aboveground frond. The frond varies in height, but may reach about 20 cm. It is divided into two segments which share a common stalk, and it is usually a deep, dull green and somewhat fleshy. The sterile segment is once pinnatifid with up to 10 usually well separated pairs of pinnae. The pinnae are variable; they are generally narrowly fan-shaped with rounded, entire margined apices, but can be broader and may be lobed or have incised margins. The fertile segment is longer than the sterile segment, is branched, and bears grape-like sporangia. Spores germinate underground and develop into minute subterranean, non-photosynthetic gametophytes which depend on an endophytic fungus for nourishment.
