Synonyms: Gleichenia linearis (Burm.f.) C.B.Clarke
Mertensia linearis (Burm.f.) Fritsch
Polypodium linearis Burm.f.
Common names:
Status: Native
Rhizome widely creeping, glabrous at maturity. Fronds spaced apart. Stipe up to 1 m long, golden brown, glabrous. Lamina 2-3 times dichotomously divided with a pair of reduced pinnae present at each fork of the divisions; pinnae narrowly lanceolate, deeply pinnatifid. Pinnule lobes 15-30 × 4 mm, linear-oblong, glabrous on both surfaces, borne only on the ultimate branches, the other axes naked. Sori subcircular, c. 1 mm in diameter, arranged in two rows along the midrib of the pinnule lobes; exindusiate.
Notes: Differs from Sticherus umbraculiferus by having pinnules only on the distal lamina axes; differs from Gleichenia polypodioides by having superficial sori that are not sunken into the lamina and pinnules that are linear.
Derivation of specific name: linearis: linear, referring to the long pinnules.
Habitat: Along moist streambanks, forest margins and roadsides, in light shade or exposed.
Altitude range: (metres) Up to 2000 m
Worldwide distribution: Widespread in tropical Africa, Madagascar region and pantropical.
