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

Ornamentation of Isoetes (Isoetaceae, Lycophyta) Microspores
The Botanical Review, 2002More than any other taxonomic character, megaspores have been used in the genusIsoetes (known by the English common name of “quillwort”), despite the fallacy of a single-character taxonomy. Microspores, on the other hand, have been largely neglected in taxonomic schemes.

Ethnobotany of Lycophyta and Polypodiophyta in Priority Terrestrial Regions of Oaxaca, Mexico
American Fern Journal, 2017Lycophyta 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.

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.

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

The Botanical Review, 2006
Abstract The microspores of Isoetes escondidensis, I. gardneriana, I. herzogii, I. pedersenii, and I. savatieri were analyzed with transmission and scanning electron microscopy. The selected species were found to be representative of the diversity found in 24 taxa previously studied that grow in southern South America.
