About Botrychium ascendens W.H.Wagner
Botrychium ascendens W.H.Wagner is a species of fern in the family Ophioglossaceae, commonly known as triangle-lobe moonwort and upswept moonwort. It is native to North America, where it occurs from British Columbia to northern California, as well as in parts of eastern Canada. It grows in a range of habitat types, including grassy riverside areas. This is a very small plant that grows from an underground caudex, and produces just one yellow-green leaf above ground. The leaf reaches up to 6 centimeters in total height, and is divided into a sterile portion and a fertile portion. The sterile portion of the leaf bears fan-shaped or wedge-shaped leaflets. The fertile portion has a very different shape, and bears tiny, grape-like clusters of sporangia that the plant uses for reproduction.
