Pollen morphological characters variation among species of Strobilanthes s.l. from Sumatra, Indonesia and its taxonomic implications

Abstract. Suratman, Suranto, Muzzazinah, Purnomo. 2022. Pollen morphological characters variation among species of Strobilanthes s.l. from Sumatra, Indonesia and its taxonomic implications.

Evolution of Angiosperm Pollen. 1. Introduction1

The methods available for such a study are examined, the effects of coding strategy, method of optimization, and starting tree topology upon inference of trait evolution are considered, and several palynological characters showed consistent, structured patterns in the context of phylogeny.

A Contribution of the Palynological Criteria in Evaluating the Relationships among some Species of Apocynaceae Sensu Lato

Light is shed on the different pollen morphological characters of the species under investigation and whether pollen morphology is considered an additional fundamental tool that helps in explanation of the evolutionary trend within the family is discussed.

Pollen studies in the genus viola (violaceae) from Iran

Abstract Pollen morphology of 17 species of Viola representing five sections, Melanium, Plagiostigma, 'Spathulidium' ined., Sclerosium, and Viola, was studied using light and scanning electron

Progress and problems in the assessment of flower morphology in higher-level systematics

It appears that apomorphic features in the strict sense are less helpful to characterize larger clades than earlier assumed, and rather apomorphic tendencies of features are more useful at this level.

Glossary of pollen and spore terminology

Pollen Diversity in Some Modern Magnoliids

It is concluded that there are no fundamental differences between pollen of the ANITA and eumagnoliid groups and the ancestral angiosperm pollen grain was probably monosulcate with a distal aperture and a homogeneous or partly granular ectexine.

Pollen Characters and Their Evolutionary Significance With Special Reference to the Flora of Karachi

The pollen morphology of 353 species from Karachi, belonging to 67 families of angiosperms, distributed in 58 dicots and 9 monocots were investigated by scanning electron microscope and light microscope and revealed great pollen diversity in their qualitative and quantitative characters.

Phylogenetics of the Hamamelidae and Their Allies: Parsimony Analyses of Nucleotide Sequences of the Plastid Gene rbcL

A parsimony analysis using nucleotide sequences of the plastid gene rbcL from 134 species found that Leitneriaceae are clearly a member of Sapindales.

A Study of the Fossil Pollen Wodehouseia Spinata. I. Ultrastructure and Comparisons to Selected Modern Taxa. II. Optical Microscopic Recognition of Foot Layers in Differentially Stained Fossil Pollen and their Significance

ABSTRACT Pollen of Wodehouseia spinata Stanley, 1961, obtained from a sample of the Upper Cretaceous Lance Formation in east-central Wyoming, was studied with the scanning and transmission electron

The Morphology and Relationships of Austrobaileya


Pollen grains of taxa representing the four described pollen types of Fagus and Nothofagus were observed with the scanning electron microscope to determine preparation effects. Pollen grains were
