|Proximal pair of pinnae (7–)10–20 cm, connected to those next above by wing along rachis; scales on costae abaxially whitish to light tan, narrowly lanceolate, mostly 3–5 cells wide at base; hairs of costae abaxially mostly less than 0.25 mm, a few sometimes to 0.5 mm; segments of larger pinnae deeply lobed; veins always forked to pinnate.

|Proximal pair of pinnae 3–10(–15) cm, sessile or slightly adnate to rachis; scales on costae abaxially tan to often shiny brown, ovate-lanceolate, usually 6–12 or more cells wide at base; hairs of costae abaxially mostly more than 0.3 mm with many ca. 0.5 mm; segments of pinna entire or crenate, rarely shallowly lobed; veins in segments of middle pinnae mostly simple.
