provided by wikipedia EN

Saccoloma is a fern genus in family Saccolomataceae.[2][3] It is the only genus in the family in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), but further investigation is needed.[2] It is pantropical and its species are found in wet, shaded forest areas.[4] Saccoloma species are characterized by an omega-shaped (Ω) vascular bundle in the cross-sections of their petioles.[5][6] The common name soralpouch fern is used for Saccoloma.[7]

Phylogeny

Saccoloma includes Orthiopteris in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), with a total of 18 species.[2] As of August 2019, Plants of the World Online accepts the following species (which may be based on a wider circumscription of the genus). Synonyms are taken from the Checklist of Ferns and Lycophytes of the World.[8]
