Monachosoraceae

Medium-size to large terrestrial ferns, the rhizome short, short-creeping and ascending to erect with clustered stipes, dictyostelic, the growing apex protected by a mucilaginous secretion in which fine brown clavate hairs are imbedded, no obvious large hairs or scales. Fronds long-stipitate, the stipes not articulate to the rhizome, grooved, with 2 lateral vascular bundles, the lamina pinnate to 4-pinnate finely divided with finely lobed ultimate pinnules, texture thin soft and herbaceous, dark, sparse to moderately dense glandular trichomes on the axes, veins free, each lobe with one vein, not reaching the margin, sori small, round or oblong, terminal on the veins or nearly so, exindusiate, sporangia mixed with glandular paraphyses, annulus longitudinal, interrupted; spores trilete, tetrahedral, finely muricate.

Distribution

A monogeneric family with c. 5 species from Malesia and tropical east Asia. In Papuasia the family is rare and represented by a single species.

Genera

A family of a single genus ... Monachosorum (1)

Note

Monachosorum is often included in the Dennstaedtiaceae where glandular sori and mucilaginous secretions are otherwise unknown. It appears that the family name may not have been validly published, but the group has been validly described as a subfamily of the Dennstaedtiaceae (Crabbe et al. 1975).
