Forking Fern Family

Gleicheniaceae

Description

provided by Flora of Zimbabwe
Terrestrial or lithophytic ferns. Rhizome thin, widely creeping, branched, apex with fringed scales or branched hairs. Fronds widely spaced, arranged in 1 row, scandent, with indeterminate growth. Lamina variously compound, pseudo- dichotomously branched with a dormant apical bud between the pairs of pinnae, herbaceous to coriaceous. Veins free, forked. Indumentum composed of stellate and branched hairs and fimbriate bracts confined to the rhizome and frond axes. Sori circular, superficial or immersed, on acroscopic vein branches, without indusia.

Gleicheniaceae

provided by wikipedia EN

The forked ferns are the family Gleicheniaceae, which includes six genera and about 160 known species.[1] The formerly independent families Dicranopteridaceae and Stromatopteridaceae are generally included in the Gleicheniaceae, whereas the Dipteridaceae and Matoniaceae, although closely related, are considered separate families by most authors.[2]

Description

These tropical ferns are the most widespread living lineage of Gleicheniales. Their rhizomes have a "vitalized" protostele or in some taxa a solenostele. The leaves are indeterminate, with pseudodichotomously forked leaves except in Stromatopteris, and free veins. The sori are abaxial but not marginal and carry 5–15 exindusiate round sporangia each. These have a transverse-oblique annulus and contain 128 to 800 bilateral or globose-tetrahedral spores. The sori and sporangia mature at the same time, and the spores grow into surface-dwelling green prothalli beset with club-shaped hairs.[2]

Systematics

There is some dispute about ranking these ferns. They are typically placed in the order Gleicheniales. They may alternatively be considered a subclass Gleicheniatae or class Gleichenopsida, so that a distinct taxon can be established for the leptosporangiate ferns. In this case, the Gleicheniaceae are upranked to an order and receive the name Gleicheniales. Irrespective of their modern taxonomic treatment, the Gleicheniaceae were formerly included in the order Polypodiales. But the ferns in the loose sense are much too diverse a group to be shoehorned into one taxon at such a low rank.[2]

The Triassic Antarctipteris and Gleichenipteris are sometimes ascribed to the Gleicheniaceae, but are probably better considered Gleicheniales incertae sedis.[2] The seven extant genera recognized as of February 2020 are:[3][4]

풀고사리과

풀고사리과(Gleicheniaceae)는 풀고사리목에 속하는 양치식물 과의 하나이다. 이전에 별도로 분류했던 발풀고사리과(Dicranopteridaceae)와 스트로마톱테리스과(Stromatopteridaceae)는 현재는 풀고사리과에 포함시켜 분류하며, 풀고사리과와 밀접한 관련이 있는 디프테리스과마토니아과는 대부분의 저자들이 독립된 과로 분류한다.[1]
