Palynology is the study of microorganisms and microscopic fragments of mega-organisms that are composed of acid-resistant organic material and occur in sediments, sedimentary rocks, and even some metasedimentary rocks.
Ever since, it has been debated in which ways and to what extent the understanding of the phylogeny of life should be used as a basis for its classification, with opinions including "numerical taxonomy" , "evolutionary taxonomy" (gradistics), and "phylogenetic systematics". From the 1960s onwards, rankless classifications were occasionally ...
For decades, most sources used a classification of the family published by Grant in 1959, but new evidence, including molecular phylogeny, veins of the corolla, pollen, and the flavonoids present, have led to reclassifications, such as the 1998 classification by Grant. [3] It recognizes two subfamilies.
Form classification, generally restricted to palaeontology, reflects uncertainty; the goal of science is to move "form taxa" to biological taxa whose affinity is known. [ 1 ] Form taxonomy is restricted to fossils that preserve too few characters for a conclusive taxonomic definition or assessment of their biological affinity, but whose study ...
Taxonomy (Greek language τάξις, taxis = 'order', 'arrangement' + νόμος, nomos = 'law' or 'science') is the classification, identification and naming of organisms. . It is usually richly informed by phylogenetics, but remains a methodologically and logically distinct discipline.
Linnaean taxonomy can mean either of two related concepts: The particular form of biological classification (taxonomy) set up by Carl Linnaeus, as set forth in his Systema Naturae (1735) and subsequent works. In the taxonomy of Linnaeus there are three kingdoms, divided into classes, and the classes divided into lower ranks in a hierarchical order.

Botany is a natural science concerned with the study of plants.The main branches of botany (also referred to as "plant science") are commonly divided into three groups: core topics, concerned with the study of the fundamental natural phenomena and processes of plant life, the classification and description of plant diversity; applied topics which study the ways in which plants may be used for ...
