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). Like other grape ferns, it depends on a mycorrhizal association in the soil.
