Tins fern suggests P. insigne Rlnme, and is more like the original than more 
recent descriptions of that species. It is well distinguished by its slenderness, 
segments connected by a wing instead of directly confluent, briefly decurrent base, 
and lax venation.

The smallest and most delicate sjiecies of the natural group of 7’. pleropns Bl. 
and P. insigne Bl., remarkable because the midribs of the segments have no 
branches visible by reflected light. .Judging bj" the description alone, P. pciila- 
phyllmn Baker is a decidedly larger and coarser fern, with shorter stipe; and 
its rhizome is said to be woody.

Near P. affine Blume, but larger and stouter, with conspicuous venation, most 
distinct in tlie clothing of the rhizome. 
The real nature of Blnine’s Polypodimn affine is not absolutely clear. The 
original description, in Flora Javae, 2: 100, is: “Filix mirifica, saepe orgyalls 
el altior.” * * * ‘Caudex as thick as the little finger, * * dull green, 
entirely naked or with scattered solitary peltate darklirown resinous-shining 
remnants of scales. * " Fronds 11 to nearly ?, feet high, 10 to 15 inches 
broad, oblong, acuminate, decurrent, membranaceous, glabrous, hlack-jmnetate
