This species conies between P. Swartzii and' P. lycopodioides. It has the
Slender rhizome and the thin texture of the first (but the chaff of the-rhi-
zome is broader and shorter), and the larger frondfe of the second. " The
venation varies a good deal even in the same frond. The paraeostal areoles
are broad, and often have a free veinlet running in from the outer margin
of the areola The sori are borne on either single veinlets or on a ..pair of
veinlets, as in Phlekpdium ; and sometimes the paraeostal areole opens into
the fruiting areole outside of it, in which case the fertile venule* bears a
short branch or two below the sorus. A single sterile frond differs ven
