Description: |
Rhizome short creeping to suberect, c. 3 mm in diameter; rhizome scales pale brown, narrowly lanceolate, entire, apex forming a long drawn out point, up to 4 mm long. Fronds simple, clustered, firmly herbaceous, erect, strongly dimorphous with the fertile fronds longer than the sterile fronds. Stipe of sterile fronds 0.4-1.8 cm long, of fertile fronds 2.5-4.6 cm, thin, densely set with almost hair-like, entire, pale brown scales up to 2 mm long. Sterile lamina 1-2 × 0.35-0.9 cm, narrowly oblanceolate to spathulate, apex rounded, base wedge-shaped and long decurrent, scales of the type of the stipe on both surfaces. Fertile lamina 0.8-1.2 × 0.6-0.85 cm, broadly elliptic to circular, base hardly decurrent, upper surface scaly as the sterile lamina, lower surface completely covered by sporangia, the two halves of the lamina often folded tightly along the midrib over the sporangia and sometimes quite difficult to unfold. |
Notes: | The small size and the distinctive scales on the lamina separate this species from others. E. spathulatum var. uluguruense has a sterile frond lenght > 4 cm and a blade width:lenght ratio 1:>4. |
Derivation of specific name: | spathulatum: spoonshaped, referring to the shape of the lamina. |
