ATHYRIUM rondoense Verdc. [family WOODSIACEAE], sp. nov. affinis A. lewalleani Pic. Serm. lamina stricte tripartita, pinnis basiscopicis partium lateralium haud anguste caudatis, pinnis, pinnulis lobisque pinnularum majoribus differt. Typus: Tanzania, Rondo Plateau, Bidgood et al. 1550 (K!, holo., BR, C, DSM, EA, MO, NHT, P, WAG, iso.)
Information
Rhizome creeping with blackish or black-veined clathrate scales ± 1.5 mm long; fronds single, 15–40 cm tall; stipe slender, 10–20 cm long with few scales and dense very short hairs. Lamina up to 20 cm long, 15 cm wide, tripartite, the parts ± confocal, each simply pinnate but pinnae very deeply divided so as to appear bipinnate; main parts broadly lanceolate in outline up to 18 cm long, 6 cm wide, acuminate but not long-caudate at the apex; each part with 6–9 pairs of pinnae up to ± 5 cm long, 2 cm wide, the apical ones reduced, toothed only at the apex, running together and narrowly decurrent into each other resembling a series of fish-tails; lower pinnae deeply divided into ± 6 elliptic lobes, the largest ± 15 mm long, 8 mm wide, ± entire to bluntly or subacutely lobed or toothed; main lobes of largest pinnae decurrent, separated by narrowly winged midrib 1–2 mm wide. Sori 1–4 per pinna-lobe, ± 1 mm wide; indusium fimbriate and hairy.
Range
DISTR. T 8 only known from the type
Altitude range
650 m
Distribution
TANZANIA Lindi District Rondo Plateau, Rondo Forest Reserve, 14 Feb. 1991, Bidgood et al. 1550!
Notes
This had been confused with Arachniodes foliosa (C. Chr.) Schelpe (Dryopteridaceae) and is superficially similar but the pinnule-lobes are not aristate-dentate.
