Sceptridium Elegans, S. × Elegans
''Sceptridium'' is a genus of seedless vascular plants in the family Ophioglossaceae, closely allied to (and often included as a subgenus of) the genus ''Botrychium'' (the moonworts and grapeferns). It is also closely related to the genus ''Botrypus'' (the rattlesnake fern, often treated as the subgenus ''Osmundopteris'' under ''Botrychium''). ''Sceptridium'' species are commonly called the grape-ferns. These plants are small with fleshy roots, and reproduce by spores shed into the air. They differ from the moonworts in having at least some sterile fronds (all fronds in ''Botrychium'' are spore-bearing), and in the fronds being bi- or tri-pinnate (''Botrychium'' are single pinnate, or rarely bipinnate); and from ''Botrypus'' in being evergreen, or at least winter-green (''Botrypus'' are deciduous) and having the non-spore-bearing part of the frond long-stalked (short-stalked in ''Botrypus'').

Sceptridium Dissectum
''Sceptridium dissectum'' is a common fern (or fern-ally) in the family Ophioglossaceae, occurring in eastern North America. Like other plants in this group, it normally only sends up one frond per year. It has long been the subject of confusion because the frond presents in one of two forms, either the normal form (forma ''obliquum'') that resembles other plants in the genus, or the skeletonized form (forma ''dissectum''). This is the most common grape fern throughout most of its range. It is a frequent denizen of disturbed lands, often growing with ''Diphasiastrum digitatum'' and ''Asplenium platyneuron''. It has an unusual growing season, with the new frond emerging in July and dying back in May. The frond often turns from green to a bronze color during the winter. Like other grape ferns, it depends on a mycorrhizal association in the soil. Description ''Sceptridium dissectum'' (Spreng.) Lyon has two separate fronds. The fertile frond looks superficially like a stalk o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sceptridium Rugulosum
''Sceptridium rugulosum'', also known as the ternate grapefern or the St. Lawrence grapefern, is a species of fern. It is an evergreen, perennial species found in the vicinity of the St. Lawrence Seaway. Description Similar to ''Sceptridium multifidum'', ''Sceptridium rugulosum'' is found in low-lying, mossy areas, although its leaves emerges in later than those of ''S. multifidum''.

Sceptridium Jenmanii
''Sceptridium jenmanii'', the Alabama grapefern or Dixie grapefern, is a species of fern in the Ophioglossaceae native to the southeastern United States. It is a rare species, and is apparently in decline. Like other grape ferns, it depends on a mycorrhizal A mycorrhiza (; , mycorrhiza, or mycorrhizas) is a symbiotic association between a fungus and a plant.
