- Diagnosis
- The new fossil is placed in the genus Davallia, due to the
presence of at least 3–pinnate fronds with free veins; sub-terminal
sori on veinlets with an abaxial extension of the ultimate veinlet along
the indusium; elongate indusia attached by the base and sides;
stalked sporangia; and annuli straight to curved, interrupted. The
spores are ±oblong-reniform, bilateral, with a perispore and
numerous, low, rounded verrucae, spreading ±radially from the
laesura.
