In order to explore micromorphologic characters in Pecluma eurybasis var. villosa (Polypodiaceae), the sporangium development and its accompanying structures were observed, using optical microscopy (OM) and transmission electron microscopy (TEM). The formation of a tapetum with a single layer of cells and non-clavate paraphyses with obtuse tips were identified as potentially important characters in the systematics of the genus. 
Ontogenia de los esporangios y esporogénesis del helecho Phymatosorus scolopendria (Polypodiaceae)
TLDR
The sori are exindusiate, superficial, vascularized and have mixed development; they are associated with uniseriate and multicellular receptacle paraphyses and sporogenesis of Phymatosorus scolopendria.

Pecluma, a new tropical american fern genus
TLDR
It is concluded that those authors who reaffirmed an alliance with Polypodium are correct, but that Copeland's error may be partly excused on the grounds that Pecluma also has many features reflecting a shared ancestry with Ctenopteris, features that mark it as abundantly distinct fromPolypodium.

TLDR
Gametophytes and primary roots of young sporophytes of the Gleicheniaceae were studied and vesicular-arbuscular mycorrhiza with a completely intracellular development of the fungus was found.
Seven new species, 13 new combinations, and one new name of Polypodiaceae from Bolivia
TLDR
Seven new species, 13 new combinations, and one new name of Polypodiaceae from Bolivia are described and three new combinations are proposed in Pecluma, and ten new combinations and onenew name in Pleopeltis.
Microtubule and actin filament organization during stomatal morphogenesis in the fern Asplenium nidus. II. Guard cells.
TLDR
The post-cytokinetic guard cells of Asplenium nidus display a prominent perinuclear microtubule system and a few microtubules under the periclinal walls, and it seems likely that the successivemicrotubule systems in guard cells are formed by putative micro Tubule organizing centres operating in a definite spatial and temporal succession.
