Description: Epiphytic, rarely terrestrial, ferns; rhizome ± erect to short-creeping, covered with clathrate scales, roots few, spongy.
Fronds usually uniform; stipe short; lamina entire, glabrous, veins anastomosing.
Sori ± sunken, a single long sorus or a line of sori on each side of the frond, marginal or submarginal, indusium absent.
Distribution and occurrence: World: c. 50 species, tropical regions. Australia: 2 species (native).
Both species of Vittaria known from New South Wales have recenty been proposed as members of the genus Haplopteris see PPG 1 and Field (2020). PlantNet currently follows the Australian Plant Census, where that change has not yet been accepted.

|1||Terminal cells of paraphyses approximately as long as wide. Rhizome scales uniformly clathrate, marginal cell walls thickened and pigmented to the same degree as medial cell walls||Vittaria elongata|
|Terminal cells of paraphyses twice or three times as long as wide. Rhizome scales with marginal cell walls thinner and less intensely pigmented than medial cells||Vittaria ensiformis|
