Pachyglossa has cristate
, spinose, and perforate perispores, whereas those of subsect.
This new species is apparently restricted to southern Brazil, and is characterized by cristate
to irregularly reticulate megaspores and microechinate microspores.
5 [micro]m in equatorial view, with an irregular cristate
type, however, seems unique among dryopteroid ferns.

Using the Lellinger and Taylor system, the following patterns are found in Isoetes microspores: aculeate, with bullae (radially symmetrical, low protuberances), no higher than wide, with a broad base and acute apex; cristate
, with walls that are narrow, sharp edged, and nonanastomosing; and echinate, with stelae (radially symmetrical, high protuberances) higher than wide, conical, widest near base.
