Ophioglossum petiolatum is a species of fern in the family Ophioglossaceae.[2] William Jackson Hooker named this species in 1823.[3]: 30 

The species occurs in parts of Asia, Australia, and North America.[1]

Common names

According to Encyclopedia of Life, in English the species goes by the common name longstem adderstongue or long-stem adder's-tongue.[2]

Some universities, including the Missouri Department of Conservation, give it the common name stalked adder’s-tongue.[4][5][6]

Description

It contains about 50 to 150 chloroplasts per epidermal cell and more than 200 in mesophyll cells.[7]

It grows quickly in pots making it suitable for botany instruction.[8]: 105 

Distribution

Ophioglossum petiolatum has a tropical and subtropical distribution in South America and Africa.[1] [9] It was probably introduced to North America early in the 1900s.[10]: 34  It is found in Hawaii[2] but may have been introduced recently.[11] It was introduced to other states in the United States.[1] In the state of Missouri it only occurs in Pemiscot County.[6] In Alabama it is present in 5 counties.[5] In Virginia it is present in 3 counties, first being reported in the state on the lawn of Tabernacle United Methodist Church in the year 1979.[12]

It is rare in New Zealand.[9] Robert Malcolm Laing was the first to record this species in Norfolk Island.[13]
