Descriptions
Asplenium terrestre Brownsey
Rhizome short, erect, bearing dark brown subulate scales up to 15 × 2 mm. Stipes 5-15 cm long, brown below, green above, covered in subulate to narrowly triangular scales with long filiform apices (Fig. 24J-N, Q-V). Laminae lanceolate to elliptic, 10-30 × 5-20 cm, dark green, leathery or very thick and fleshy, slightly drooping or stiff and upright, bi- to tripinnate. Raches green, scaly, prominently ridged. Pinnae 7-20 pairs, those at the base ovate, those above very narrowly ovate or elliptic, acute to acuminate, stalked, 3-10 × 0.5-3 cm, covered on underside in tiny scales. Upper pinnules linear, acute, entire and sessile; lower pinnules ovate to narrowly elliptic and pinnatifid or pinnate, up to 30 × 10 mm. Sori submarginal, 2-7 mm long. Spores (38)43-51(56) mcm long, (25)29-34(38) mcm wide (14 populations), perispore prominently winged and ridged (Fig. 30 O-R). 288 chromosomes in the sporophyte; 144 bivalents at meiosis.
