The more or less cylindric petioles are generally dark or reddish brown to blackish, with a shiny, glabrous character. Leaf blades are one to four-pinnate, with segments generally stalked and free, linear to rounded, sometimes lobed, often folded lengthwise when desiccated. The blade veins are normally free. Sporangia are exhibited in generally continuous, submarginal bands, sometimes among a whitish to yellowish exudate. Segment margins are typically recurved; spores are most often tan to light yellow.
