Davallodes urceolatum Copeland, 1927
Description
Rhizome without the scales 4-7 mm in diametre (D. urceolatum Rhizome). Scales nearly black without pale border, distinctly acicular, with marginal setae at least in distal part or lacking marginal setae, basifixed with cordate base and much overlapping basal lobes, 15 mm long. Stipes dark brown, 5-19 cm long. Lamina compound (D. urceolatum Habitus), bipinnate towards base and in the middle part, bearing multicellular hairs, 20-80 cm long by 8-12 cm broad, lower pinnae not very small, about one third to about as long as the longest. Hairs between veins on both surfaces. Longest petiolules 1 mm long. Longest pinnae 5-9 cm long by 1.5-2.5 cm broad. Longest pinnules or pinnalobes 8-15 mm long by 3-5 mm broad. Hairs on leaf axes 0.2-1 mm long. Indusium also attached along the sides, pouch-shaped, oblong, longer than wide or about as wide as long, 0.7 mm long by 0.5-0.6 mm broad. Indusium lips truncate, separated from or even to laminar margin (D. urceolatum SEM, picture of indusia).
Distribution
Malesia: Sumatra (Karo Plateau near Berastagi 4 coll.; Kerinci 2 coll.).
Note
Two of the four collections were identified by Holttum as Davallodes hirsutum , from which this species differs in the cordate basally attached rhizome scales and the longer lowest pinnae.
