Description: |
Rhizome shortly creeping rhizome, c. 4 mm in diameter; scales dark-brown, lanceolate, entire, up to 4 mm long. Fronds simple, closely spaced, erect, glabrous. Stipe up to 5 cm long, glabrous. Sterile lamina simple, 16-30 (including fertile segment) × 1.5-2.3 cm, narrowly elliptic in outline, base tapering, margins entire. Fertile segment linear, situated on top of the sterile lamina, c. 50 × 3 mm. Sori are spread out over the underside of the fertile segment. |
Notes: | The fertile segment on top of the sterile lamina makes it easy to distinguish B. spicata from other species. |
Derivation of specific name: | spicata: arranged in a spike, referring to the fertile segment at the apex of the frond. |
Habitat: | Epiphyte or lithophyte in low-altitude, semi-deciduous forest in montane areas. |
Altitude range: (metres) | 780 - 1300 m |
