as the rachis stramineous paleaceous with subulate ciliated 

 ferruginous scales, fronds firm-membranaceous villoso-squa- 

 mose 1-H foot long 2-3| inches broad lanceolate acuminate 

 attenuate and subpinnate below, the rest deeply pinnatifid 

 nearly to the rachis, segments patent approximate and with a 

 very narrow and acute sinus or wider apart and broad sinuses 

 with 1-2 short triangular confluent lobes in these sinuses, 

 from a dilated base oblong-acuminate, those closely placed 

 are entire or crenato-lobulate, the distant ones pinnatifid with 

 ovate or rounded lobes, the axillary lobes (those in the si- 

 nuses) entire often fertile, veins pinnated, sori dorsal upon 

 the veinlets small, capsules few mixed with long hairs. — •

 IVilford. — A very peculiar and distinct species. Most of the specimens from 

 Formosa are simply pinnatifid, with close-placed segments, and no intermediate 

 lobes ; yet they are mature and copiously soriferous : others of them exhibit a 

 passage to what may be considered the normal form. Kunze and others consider 

 the small tuft of hairs in the sori to arise from a small scale or imperfect invo- 

 lucre.

 or ascending scaly, stipites tufted short 1-2 inches long par- 

 tially scaly, fronds 6-10 inches long 1-2 inches broad lan- 

 ceolate acuminate much attenuated below firm subcoriaceo- 

 membranaceous opaque pinnate often for their whole length, 

 generally pinnatifid at the apex and sometimes the rachis 

 runs out into long nearly naked decurved and rooting apex, 

 pinnae subpetiolate horizontal i-1 inch long hastate (the 

 margin entire), uppermost oblong sessile without basal lobes 

 and at the apex confluent, lowermost dwarfed ones reflexed, 

 veins simple or forked quite free in the upper half bearing 

 each a dorsal sorus between the costa and the margin. — Sw.
