20. Nephrolepis arida D.L. Jones

Nephrolepis arida D.L. Jones (1988) 474 . - Type: Jones 1598 (holo DNA n.v.; iso K), Australia.

The duplicate in K of the type of this species is a well-developed plant, with basal scales somewhat thickened in the best developed tuft, and spreading sideways away from the stipe exactly like in N. biserrata . Sori are irregularly shaped, most reniform, but some are more athyrioid with unequal base, and none contain well-developed sporangia. On the whole, the characters of this specimen are consistent with a hybrid origin involving almost certainly N. biserrata and possibly N. cordifolia , but considering that the specimens occur in sites where the growth conditions for Nephrolepis appear to be marginal, it may also represent a somewhat aberrant specimen of the former.
