Lunathyrium . Closely related Asian ferns have been treated as conspecific with Deparia acrostichoides , but D . acrostichoides differs from them in having creeping stems with rather distant leaves and pinnate-pinnatifid leaves. Deparia acrostichoides and Asian species such as D . pycnosora (H. Christ) M. Kato and D . allantodioides (Beddome) M. Kato are examples of vicariant species pairs with amphipacific disjunct distributions.
