Quite frequent in shady rock crevices and woods, especially on limestone. Fronds 5-35 cm, longest pinnae 1-4 cm Skye ID: General appearance is like a smallish Lady Fern. Stalks have very few scales, apart from at the base, those higher up on the rachis being hair-like. Rachis is black in lower part, then green. The longest pinnae are at or a little below the middle, but they hardly diminish in size from there to the lowest, so the general appearance of the frond is parallel-sided in the lower half and then tapering evenly in the upper half. (Lady Fern tapers to both ends) The pinnules nearest the rachis are well separated. Other features: Forms small tufts of typically 6-8 fronds as in picture below. Sori round, partly covered with a white oval undivided indusium. |
