Amauropelta

Amauropelta is a monophyletic genus of fern, the largest in the Thelypteridaceae family, with 233 species. The center of diversity of the genus is in the Neotropics, but the earliest-diverging lineages are from the Old World. The genus Amauropelta is very similar morphologically to the other two genera of the amaropeltoid clade, Coryphopteris and Metathelypteris, differing from the first in the lack of sessile, resinous, reddish glands on the lamina between veins (except in the A. resinifera group) and from the second by the veins running to the margins. Within the Thelypteridaceae in the Neotropics it is easily recognised by the pairs of gradually reduced proximal pinnae, which vary from few to many, depending on the species, and the veins usually prominent abaxially and adaxially, with the lowermost pair from adjacent segments running to the margin just above the sinus between adjacent lobes, rarely (in A. linkiana) running to the sinus, and never united to form excurrent veins tha......read more on Wikipedia.
