Dryopteridaceae, JP Roux, M Shaffer-Fehre, B Verdcourt. Flora of Tropical East Africa. 2007

Type
Nepal, Wallich 377 (K-Wall.!)
Morphology General Habit
Terrestrial.
Vegetative Multiplication Rhizomes
Rhizome erect, to 20 cm high, covered in scales (not seen in East African material)
Morphology Leaves
Fronds tufted, dimorphic, to 1.5 m long.
Morphology Leaves Stipes
Stipe straw-coloured, later mahogany-coloured, to 70 cm long, near base with dark brown ovate scales 1–10 × 0.4–2 mm, acuminate, with paler margins, stipe near apex with multicellular glandular trichomes ± 0.3 mm long.
Morphology Leaves Pinnae
Pinnae in 6–8 pairs, the lowermost to 42 × 27 cm and longest, with stalks of 1.5–3 cm, others much shorter and gradually adnate to rachis by basiscopic half; basal pinnules largest, to 16 cm, with basiscopic part of pinna broader, basal few pinnules free, other pinnules joined by a continuous wing; ± straight free veinlets in central areoles, absent along costae.
Morphology Leaves Leaf lamina
Lamina with some hairs near margin plus glandular trichomes to 0.4 mm restricted to in and near sinus, and each areole with a single trichome to 0.3 mm; sori almost marginal, 1–2 mm in diameter. Lamina mid- to dark green, subcoriaceous, sterile lamina deltoid in outline, to 68 × 64 cm, the fertile lamina almost lanceolate above the wide basal pinnae, 50–108 × 43–84 cm, 3-pinnatisect.
Morphology Reproductive morphology Sori Indusium
Indusium round, persistent, sometimes flabellate
Figures
Figure 1: 1-7, figure 2:1
Ecology
Moist forest; 1000–1900 m
Conservation
Widespread; least concern (LC)
Note
Blunt-rounded lobes of the decurrent lamina fill gaps between tissues of blade before the lamina expands; probably an adaptation to support increased photosynthesis in the deep shade of the plant’s habitat.
Distribution
