Lomariopsidaceae, A.H.G Alston. Flora of West Tropical Africa. 1959

Habit
Epiphytic or terrestrial; rhizome wide (rarely short) creeping or climbing, dorsiventral in structure with roots arising from the ventral surface; leaf–bases more or less decurrent as ridges on the upper surface of the rhizome; apex of rhizome covered with scales which may be cordate but not peltate; stipes jointed near the base in Elaphoglossum, with several vascular strands arranged in a U
[FTEA]

Lomariopsidaceae, John T. Mickel. Flora of Tropical East Africa. 2002

Habit
Terrestrial, lithophytic, epiphytic or hemi-epiphytic ferns
Rhizomes
Rhizomes short- to long-creeping or climbing, clothed with scales
[FTEA]

Oleandraceae, B. Verdcourt, B.Sc., Ph.D.. Flora of Tropical East Africa. 2001

Habit
Terrestrial or epiphytic plants or sometimes on rocks
Rhizomes
Rhizomes erect or creeping, dictyostelic, with peltate scales, sometimes producing tubers
[FTEA]

Dryopteridaceae, JP Roux, M Shaffer-Fehre, B Verdcourt. Flora of Tropical East Africa. 2007

Habit
Terrestrial, epilithic or low-level epiphytic plants with dictyostelic, erect or creeping, often stoloniferous rhizomes bearing scales
Leaves
Fronds spaced or tufted, monomorphic or dimorphic.
Stipes
Stipes mostly dark at the base, adaxially sulcate or with a central ridge in Lastreopsis, with two larger circular vascular bundles dorsally and two or more smaller ones ventrally, not articulated, variously set with scales and/ or hairs.
Rachis
Rachis sulci open or, if present, closed to the sulci of the lower order axes.
Leaf lamina
Lamina 1–4-pinnate, anadromous and/ or catadromous, the basal pinnae often basiscopically developed, often with proliferous buds along the lamina axes, variously set with scales, hairs and glands along the veins and lamina surfaces.
Leaf veins
Venation forked or pinnately branched, free or anastomosing, with or without included veinlets, veins mostly ending near the lamina margin
Sori
Sori circular or elongate, dorsally on veins or at vein endings, often on an abbreviated vein branch, receptacle with or without simple paraphyses; indusium reniform, circular, elongate, or exindusiate, peltate or marginally attached.
Note
The Dryopteridaceae as construed here is often treated as two independent families, Dryopteridaceae sensu stricto consisting of Didymochlaena, Cyrtomium, Polystichum, Nothoperanema, Dryopteris and Arachniodes, and Tectariaceae, which includes Tectaria, Triplophyllum, Lastreopsis, Ctenitis, Hypodematium and Megalastrum. Tectariaceae is characterised by raised costae and costules, presence of acicular and/ or ctenitoid hairs, and a chromosome number based on n = 40 or 41. In Dryopteridaceae sensu stricto the costae and costules are adaxially sulcate, never bear acicular or ctentoid hairs, and have a chromosome number based on n = 41. As treated here the family consists of 28 genera and approximately 1050 species.

Grammitidaceae, A.H.G Alston. Flora of West Tropical Africa. 1959

Habit
Epiphytes or rock plants with creeping or ascending solenostelic rhizomes or vascular system somewhat dissected; scales brown, often with stiff unicellular hairs
[FTEA]

Grammitidaceae, B. S. Parris, M.Sc., Ph.D.. Flora of Tropical East Africa. 2005

Habit
Usually epiphytic ferns, sometimes terrestrial and lithophytic, occasionally facultative rheophytes Usually epiphytic ferns, sometimes terrestrial and lithophytic, occasionally facultative rheophytes
Rhizomes
Rhizomes erect to long-creeping, usually scaly Rhizomes erect to long-creeping, usually scaly
[FTEA]

Davalliaceae, B. Verdcourt, B.Sc., Ph.D.. Flora of Tropical East Africa. 1999

Habit
Epiphytic or terrestrial, less often on rocks; rhizome short- to long-creeping, densely clothed with often cordate or peltate sometimes toothed often clathrate scales which have hairs (often glandular) on the surface and/or margin
[FWTA]

Davalliaceae, A.H.G Alston. Flora of West Tropical Africa. 1959

Habit
Epiphytes with wide–creeping rhizomes, rarely terrestrial or suberect (Nephrolepis); tubers sometimes present (Nephrolepis); scales peltate; stipes jointed to the rhizome, except in Nephrolepis and Arthropteris where the pinnae are jointed to the rhachis
