Description
Genus Deparia
Plants
terrestrial
. Stems creeping
, stolons absent. Leaves monomorphic
, dying back in winter. Petiole
1/3--2/3 length
of blade
, base
swollen and persisting as trophopod over winter or not; vascular bundles
2, lateral
, lunate
in cross
section
. Blade elliptic to ovate-lanceolate, 1-pinnate-pinnatifid [pinnatifid
to 3-pinnate-pinnatifid], gradually reduced distally to pinnatifid apex, herbaceous. Pinnae not articulate
to rachis, segment margins
entire, crenulate
, or serrate; proximal
pinnae (several pairs) reduced or not, sessile, equilateral
; costae adaxially shallowly grooved
, grooves
not continuous with that of rachis; indument
on rachis and costae (both sides) of multicellular
hairs
. Veins free
, simple
or forked
. Sori on veins, elongate
, ± straight, or hooked
at distal end; indusia linear
, laterally attached, persistent
. Spores brownish, broadly winged
. x
= 40.
Species ca.
50: North America, e Asia, se and tropical
Africa including Madagascar, Pacific Islands, Australia.
Petiole bases are swollen and toothed
in sect. Lunathyrium (Koidzumi) M.
Kato but not or only slightly thickened and without teeth in sects. Athyriopsis (Ching) M. Kato, Deparia, and Dryoathyrium (Ching) M. Kato.
Two American species, one native
and the other introduced
, are usually placed in Athyrium or Diplazium. The genus Deparia, however, including these two species, is sufficiently distinct
to warrant generic
separation
because of its nondecurrent costal grooves and the presence of multicellular hairs on blades (M. Kato 1984).[1]
