- Type
- Type: Guinea, Labè, Chevalier 12385 (P, holo.; BM!, photo)
- Morphology Stem Caudex
- Caudex short-creeping or ± erect with fronds densely tufted
- Morphology Leaves Stipes
- Stipe 25–56 cm long, glabrous or with minute capitate hairs
- Morphology Leaves Leaf lamina
- Lamina narrowly oblong, 30–45 cm long, 15–20 cm wide, with 1–4 pairs of very reduced pinnae, 3–10 mm long (these have been ignored in calculating stipe and lamina lengths).
- Morphology Leaves
- Pinnae narrowly oblong, up to 12 cm long, 1.5 cm wide, acuminate, very deeply pinnatifid almost to costa; lobes narrowly oblong to lanceolate, 6–10 mm long, 1.5–2.2 mm wide, straight or somewhat falcate, rounded to acute at apex, with dense small yellowish glands beneath; costules ± 2.5 mm apart; veins not anastomosing; sinus membranes thickened
- Morphology Reproductive morphology Sori Indusium
- Indusia small with very few to many small yellowish glands.
- Ecology
- River banks; ?900–1650 m
- Note
- In his key, Schelpe states ‘indusios pilosos’, so some doubt must rest on his records from Angola. The specimens cited above had ‘guineensis’ written on in pencil in B. Parris’ handwriting and I am sure this is correct.
