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.
