Lamina 2–3-pinnate at base, ovate or triangular, 8–31 cm long, 4.5–22 cm wide, slightly leathery, sparsely scaly. Primary pinnae in 9–15 pairs, ovate to triangular or narrowly triangular; apices acute to obtuse (rarely acuminate); longest pinnae at or near base, 2.2–14 cm long, 1.5–5.5 cm wide. Secondary pinnae ovate or elliptic; bases unequally cuneate, mostly stalked; margins often deeply incised; apices rounded or truncate and toothed; longest secondary pinnae 9–28 mm long, 6–21 mm wide, sometimes divided into tertiary pinnae up to 14 mm long and 8 mm wide.
