Loto subbiflori-Chaetopogonetum fasciculati), sobre litosuelo arenoso con encharcamiento temporal y algo alterado, en un rellano de roquedo granitico, asi como en el interior de una pequena cubeta inundada del mismo, en una zona localizada entre pinares de Pinus pinaster y Pinus radiata, y en compania de Isoetes
histrix, Thrincia aff.
The spores of Pteridophyta, Isoetes
and Sphagnum were counted and quantified as percentages based on the pollen sum.
Morphology, ultrastructure and typology of orbicules in Isoetes
Constant species: Isoetes
echinospora, Potamogeton perfoliatus, Subularia aquatica.
Por otra parte, algunas especies que restringen su area a zonas de alta montana, como Callitriche heterophylla, Isoetes
mexicana, Jaegeria glabra, Ranunculus hydrocharoides y R.
A new species of Isoetes
(Isoetaceae) from Turkey, with a study of microphyll intercellular pectic protuberances and their potential taxonomic value.
melanopoda, Croomia pauciflora, Brickellia cordifolia, and Stewartia malacodendron were not re-located.
In the latter case, for example, no species of Isoetes
were reported for Mississippi in 1969, and today three are recognized, with the potential of several more.
Spores of Isoetes
lacustris were found at three sampling points from the eastern shore: VM38 (D 2.
The dominant species of marsh vegetation is Phragmites australis, and the companion species include Potentilla anse-rina, Salix brachypoda, Alisma plantago-aquatica, Isoetes
acustris, and Plantago asiatica.
However, like in the coverage groups, the LCB3 lakes are characterized by the lowest and the highest values also for macrophyte growth depth, which depends mainly on the presence of a moss polster, because in Estonian lakes the growth limit is mostly 2 m for Isoetes
and 1 m for Lobelia.
Wetland or semi-aquatic plant pollen from types such as Cyperaceae (sedge f amily), Typha latifolia (cattail), Sphagnum, and Isoetes
(quillwort) are present in these samples but they are not abundant (Fig.
