Ophioglossum reticulatum - L.
                 
Common Name Adder?s tongue fern
Family Ophioglossaceae
USDA hardiness 10-12
Known Hazards Although we have found no reports of toxicity for this species, a number of ferns contain carcinogens so some caution is advisable[200 ]. Many ferns also contain thiaminase, an enzyme that robs the body of its vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase[172 ].
Habitats Grassland in open damp sandy soil at elevations up to 1,500 metres in Africa[200 , 299 ]. Moist sandy soils, seasonally wet soils, along roads, on termite hills, in montane grassland among rocks and forest margins, from sea-level up to 2,500 metres[299 ].
Range Pantropical.
