A new heterosporous fern species, Azolla boliviensis sp. nov., is described from latest Maastrichtian (latest Cretaceous) to Paleocene (earliest Palaeogene) terrestrial sediments of the Eslabón and Flora Formations, Subandean belt, Bolivia. The species is represented by dissociated but abundantly co-preserved megasporocarps, megaspores, microsporangia, massulae and microspores. The genus consistently characterizes warm-climate lacustrine settings. Fossil Azolla is first identified around the…

Azolla Sporophytes and Spores from the Late Cretaceous and Paleocene of Patagonia, Argentina
TLDR
The inability to fully classify A. keuja to section, in combination with the great morphological diversity of fossil Azolla, indicates that a comprehensive reevaluation of phylogeny and taxonomy that incorporates both extant and fossil species is needed.

STUDIES ON FOSSIL AZOLLA: AZOLLA MONTANA, A CRETACEOUS MEGASPORE WITH MANY SMALL FLOATS
TLDR
Azolla montana is a new species from the late Cretaceous which has a megaspore apparatus with a single large and conspicuous columella which resembles the floats of the megaspor apparatus of many extant species; it is suggested that the floats were derived, phyletically, by segmentation of the colum Bella.

A CONTRIBUTION TO THE EARLY TERTIARY FOSSIL RECORD OF THE SALVINIACEAE
TLDR
The columella of the floating apparatus of the megaspore apparatuses of Azolla appears to be a phylogenetic localization of the perispore around themegaspore, suggesting a less specialized condition than in living species, where these two structures differ greatly in size.
