Gleichenia rupestris
R.Br.Rachis of major branches glabrous, with occasional, scattered fringed scales. Ultimate branches linear, 3–5 cm long, with close-set pinnules; undersurface of pinna-rachis without hairs or scales, usually glaucous; uncoiling tips (and young rachises) glaucous, with scattered fringed scales. Pinnules c. 1–2 mm long, oblong-ovate to semicircular, blunt, lower surface glaucous, flat or slightly concave (not inrolled on all edges to make a pocket). Sori with 3–4 sporangia grouped around central projection; sporangia dull, yellow-brown.
GGr, EGL. Also Qld, NSW. Occurs along the east coast of Australia, extending south to far eastern Victoria (Wingan Inlet area and Sandpatch Wilderness) where uncommon, occurring in seepage areas of sea-cliffs.
The glaucous ultimate rachises and pinnule undersurface are distinctive, although the degree of glaucousness is variable. The more or less glabrous rachises and branches are diagnostic.
