(3) Blunt-Lobed Woodsia. Woodsia Obtùsa
Fronds broadly lanceolate, ten to eighteen inches long, nearly twice pinnate, often minutely glandular. Pinnæ rather remote, triangular-ovate or oblong, pinnately parted into obtuse, oblong, toothed segments. Veins forked. Fruit-dots on or near the margin of the lobes. Indusium conspicuous, at length splitting into several spreading, jagged lobes.
This is our most common species of Woodsia and it has a wider range than the others, extending from Maine and Nova Scotia to Georgia and westward. On rocky banks and cliffs. The sori of this species have a peculiar beauty on account of the star-shaped indusium, as it splits into fragments. Var. angústa is a form with very narrow fronds and pinnæ. Highlands, New York. The type grows in Middlesex County, Mass., but is rare.
