Morphology and ultrastructure of megaspores and microspores of Isoetes savatieri Franchet (Lycophyta)

Review of Palaeobotany and Palynology, 2003
Abstract The general morphology, organization, structure and ornamentation of the sporoderm of megaspores and microspores of Isoetes savatieri Franchet have been studied with a stereoscopic microscope, light microscopy, transmission and scanning electron microscopy.

Ethnobotany of Lycophyta and Polypodiophyta in Priority Terrestrial Regions of Oaxaca, Mexico

American Fern Journal, 2017
Lycophyta and Polypodiophyta have been used by humans worldwide since ancient times, yet little has been documented. This paper analyzes and discusses the different uses of these plants in three Priority Terrestrial Regions (PTR) of conservation in the state of Oaxaca in Mexico.

Connective structures between tapetal cells and spores in Lycophyta and pollen grains in angiosperms — A review

Review of Palaeobotany and Palynology, 2009
This article is a review of research and accumulated information about connective structures between, respectively, microspores in the locular space in anthers of angiospermis and the spores in the megasporangia of Lycophyta, as well as a comparison between these structures.

Megaspore wall in Lycophyta-ultrastructure and function

Review of Palaeobotany and Palynology, 1995
Abstract New contributions on megaspore walls in the genus Selaginella are presented. The study was carried out with electron microscopy (SEM and TEM), light microscopy including phase and differential interference contrast, fluorescence and confocal microscopy.

Ultrastructural analysis of sporoderm development in megaspores ofSelaginella galeottii (Lycophyta)

Plant Systematics and Evolution, 1991
Structural members within the exospore ofSelaginella galeottii suggestive of those present at maturity are first detectable when the exospore is approximately 5 µm in thickness. Subsequent changes in successively larger sporangia involve a gradual size increase of the component units simultaneously throughout the exospore.

Phenology and Geographic Extension of Lycophyta and Fern flora in Nokrek Biosphere Reserve of Eastern Himalaya

Proceedings of the National Academy of Sciences India Section B - Biological Sciences, 2014
Tropical and subtropical hilly vegetation in Himalayan regions are well suited for the taxonomical research because of the diverse habitat available in close proximity and the regions promote high species richness and endemism due to variation in slopes, soils, rocks, microclimate, exposure, latitude and altitude. Pteridophytes have evolved to fill the

Environmentally Related Demography: Field Studies on Isoëtes Lacustris L. (Lycophyta, Isoëtaceae) in Europe

2003
At each population level studied (plant, leaf, and megaspore) a relationship between growth conditions and Isoetes L. performance was recognized that is in the leaf number per rosette, leaf surface area, megaspore number and size. Leaf number per plant and variation coefficient proved to be dependent on plant density. Data of plant dry mass and density
