Arachniodes simplicior ("Hakatashida")
Japanese name: ハカタシダ (博多羊歯)
Scientific name: Arachniodes simplicior
[Overview]
An evergreen fern growing on cliffs and forest edges in somewhat dry woods in hills and low mountains.
It seldom forms colonies.
A short rhizome creeps.
The fronds are twice pinnately compound, ovate-elliptic, 30–40 cm long and 15–35 cm wide.
The lateral pinnae are linear-lanceolate with pointed tips; the lower 3–5 pairs are large and widely spaced and very conspicuous, while the pinnae above them become smaller and form the terminal pinna.
On the lower side of the base of the lowest lateral pinna there is a pinna of almost the same shape as the lateral pinnae.
The upper surface of the frond is dark green and glossy, sometimes with white to cream markings along the pinna axis, and the margins of the pinnules have pointed teeth.
The sori are borne midway between the midrib and the margin of the pinnule, and the indusium is round-reniform, with an entire or slightly wavy margin.
The stalk is 25–45 cm long and pale straw-colored, with brown scales fairly densely attached at the base.
[Cultivation]
Propagate by division.
It prefers a place in partial shade that is well drained and retains water well.
It prefers an environment with high air humidity.
It is easy to grow.
Fertilizer is not particularly necessary.
There are no particular pests or diseases.
[Notes]
The Japanese name is said to compare the pattern of the leaves to Hakata-ori (Hakata woven fabric), but there is also a theory that it means a "hard-leaved" fern.
