  • ALMOST THRICE-CUT FERNS 27 COMMON WOODSIA 14" D-E Woodsia obtusa is a small fern of limestone cliffs and soils, and is not common in the Park. The stems are brown at the base and yellow at the leaf, scaly when young and smooth when mature. The sori are enclosed in rounded sacs that split into star-like shapes that are soon hidden by the developing sori. The veins that lead to the sori do not reach the leaflet margins. This species is also called blunt-lobed cliff fern. 28 HAIRY LIPFERN 8" E Cheilanthes lanosa is another fern of limestone slopes and ledges, often of dry, sunny exposures, and very rare in the Park. The entire plant is hairy. The sori are hidden in the rolled-over margins of the thick, leathery leaflets. 29 HAV-SCENTED FERN 16" D Dennstaedtia punctiloba does best in moderate shade or full sun, and is one of the more common ferns in the Park. The leaf is yellow-green, soft, and the leaflet edges are often curled under. The stem and the underside of the leaflets have a wealth of silvery hairs, each tipped with a tiny glad from which issues the odor of newly-mown hay. The sori are enclosed in minute cups at the leaflet margins. 30 UPLAND BRITTLE FERN 10" D Cystopteris protrusa is widespread within the Park, without being common. It is found in shaded locations with rich soil. The leaflets are few and short. The sori mature in open cups from which they soon break free and hide, to resemble those of other species that possess no indusia. Several varieties of this species have been described from this area. 31 BULBLET BRITTLE FERN 30" D Cystopteris bulbifera is rare in the Park. Its leaflets resemble those of the brittle fern, but the stems are much longer and trending downward. Bulblets frequently develope at the juncture of the stem and the leaflet; these can take root and become new plants. Ferns of the Cystopteris family are also called bladder ferns, and this species bulblet fern. 32 COMMON WOOD FERN 24" E Dryopteris intermedia is common throughout the Park, preferring shaded woodlands. The stem is scaly, the leaves are soft and green, and each sub-leaflet has half a dozen or more sharp points. The indusium is circular, and covered with stalked glands. This fern is also called fancy fern. 33 MOUNTAIN WOOD FERN 24'" D Dryopteris spinulosa is extremely abundant in the spruce-fir forests. It is almost identical with the common wood fern, but has fewer leaflets, no glands on the indusium, and the subleaflet closest to the stem on the underside of the lowest leaflet is longer than the one next to it. 12 W mf
