Moonwort
''Botrychium'' is a genus of ferns, seedless vascular plants in the family Ophioglossaceae. ''Botrychium'' species are known as moonworts. They are small, with fleshy roots, and reproduce by spores shed into the air. One part of the leaf, the trophophore, is sterile and fernlike; the other, the sporophore, is fertile and carries the clusters of sporangia or spore cases. Some species only occasionally emerge above ground and gain most of their nourishment from an association with mycorrhizal fungi. The circumscription of ''Botrychium'' is disputed between different authors; some botanists include the genera '' Botrypus'' and '' Sceptridium'' within ''Botrychium'', while others treat them as distinct. The latter treatment is provisionally followed here.

Botrychium Lunaria
''Botrychium lunaria'' is a species of fern in the family Ophioglossaceae known by the common name moonwort or common moonwort. It is the most widely distributed moonwort, growing throughout the Northern Hemisphere across Eurasia and from Alaska to Greenland, as well as temperate parts of the Southern Hemisphere. Description This is a small plant growing up to in height from an underground caudex. The leaf is pinnate and is divided into a sterile frond and a fertile frond. The sterile frond of the leaf has 4 to 9 pairs of fan-shaped leaflets or pinnae. The fertile part of the leaf is very different in shape, with grapelike clusters of round sporangia producing spores by which it reproduces. As in other members of the family Ophioglossaceae, this species is eusporangiate, the sporangia derived from more than one initial cell and having sporangial walls more than one cell thick. Their spores develop into underground, mycotrophic gametophytes. Moonworts die down at the end of su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
