  • TWICE-CUT FERNS 20 ROYAL FERN 40" D Osmunda regain is a bog-land plant, where the soil is acid and the roots can grow in water The spores develope at the top of the stem, in tiny spheres. Many leaves spntvj from the same rootstock, but only a small percentage are fertile and bear son 21 MOUNTAIN SPLEENWORT 4" E Asplenium montanum occurs only on shale outcroppings from which spring water contmu.iiiy seeps. Unlike other spleenworts, this species has leaflets with notched tips sori, as in all spleenworts, have long, narrow indusia The plant is ahonrian' within its restricted habitat. 22 MAIDENHAIR FERN 16" D Adiantum latum is unique in that the stem divides, rather than branches, and the ItaftaU have a distinctive shape. The sori are hidden in turned-over leaf margins. This is a common fern of damp and shaded woodlands. 23 CLIFF-BRAKE 12" E Pellaea atropurpurea stands in full sunlight on limestone cliffs, and is rare in the Park The son grow along the leaflet margins, protected by the turned-under edge. The stem is a dark purple and quite hairy. The fertile leaves are usually longer and more sharply pointed than the infertile ones. This species is also called purple cliff brake and hairy cliff-brake. 24 GIANT WOOD FERN 36" E Dryoptens goldiana requires rich woodland and deep shade. It resembles the more common marginal wood fern, but is larger in all dimensions. It is not common in the Park The indusia are circular, hairy, and are borne near the middle of the sub leaflet The plant is also known as Goldie's fern. 25 MARGINAL WOOD FERN 15" E Dryopteris margmalis does well in rich or poor soil, in both sun and shade. The stalk is scaly, the leaves are dark green, and the mid-rib of the leathery leaflet shows a marked curving from side to side. The circular sori are covered with large, hairless m dusia, and are located on or very close to the leaflet margin. This abundant fern is also called leather woodfern and marginal shield fern. 26 LADY FERN 30" D Athyrium asplen.oides has a lacy, fine-cut leaf, generally quite broad, with a sharply pointmq tip It is common in the Park, of wide distribution, and flourishes at high elevations The stalk is scaly when young, and almost smooth when mature. The shar- the sub-leaflet is somewhat variable, more deeply incised in some specimens than in others. The indusia are long and narrow. Both marginal and common wood ferns, in the lowest rank of leaflets, have sub-leaflets on the stem side that are longer than the sub-leaflets above them; in the lady fern, the sub-leaflets are o* equal size. 10
