Pecluma pilosa (A.M.Evans) M.Kessler & A.R.Sm., Candollea 60(1): 281. 2005.

= Pecluma ptilodon (Kunze) M.G.Price var. pilosa (A.M.Evans) Stolze, Fieldiana, Bot. , n.s., 32: 124. 1993.

Range: — Trinidad; Guyana and Venezuela to Bolivia (CO, LP, PA) and Brazil.

Ecology: —Common; epiphytic, less commonly on rocks or fallen logs, in humid forests; 250–1500(2600) m.

Notes: —Superficially resembling P. consimilis (Mett.) M.G.Price , but differs by its generally narrower blades (mostly to ca. 8 cm vs. to 12 cm), narrow middle pinnae (3–6 mm vs. 8–10 mm) with many more pairs of gradually reduced pinnae (sometimes 25+ pairs) nearly to the rhizome (and hence, shorter petioles), longer septate hairs (often exceeding 1 mm) along the rachises abaxially, and presence (seen in only very young or undeveloped sori) of erect, short hairs in patches around the sori (such hairs apparently lacking in P. consimilis ). Possibly a tetraploid species (spores ca. 47 μm long).

According to Evans (1969), P. consimilis has a range that includes the Greater Antilles and southern Mexico to Venezuela and Colombia. It differs from P. eurybasis by much shorter petioles (1/7–1/20 vs. 1/2–1/5 of rachis length), pinnae basally reduced to obtuse or rounded lobes, and entire pinnae (vs. often crenulate or crenate), and from P. pilosa by blades abaxially glabrous or with minute (0.1 mm long), evenly dispersed hairs (vs. hairs in patches around the sori). Pecluma pastazensis (Hieron.) R.C.Moran , from Colombia and Ecuador, treated as a variety of P. consimilis by Evans, is another similar, closely related species.
