Plant nomenclature and taxonomyTaxonomy is the science of naming of leaving organisms and their correct integration into the existing system of nomenclature.

The exact naming (taxonomy) and an understanding of the species relationship to other species is an essential basis for pharmacognostic

work.

Only taxonomy allows the correct identification of a botanical drug, and consequently is the basis for further pharmacological, phytochemical, analytical, and clinical study.

By Dr. Youssef Ibrahim Ph.D.

Plant nomenclature and taxonomy

Morphological and microscopical character of the plant organs plays an important role in identifying a botanical drug.

Based on the analysis of character, plants are classified into the following levels or categories:

Kingdom

Phylum: (plural=phyla)

Class

Order

Family

Genus: (plural=genera)

Species

Each formal grouping at any given level is a taxon (pl.,taxa)

By Dr. Youssef Ibrahim Ph.D.

Plant nomenclature and taxonomyClosely related species grouped together in a common genus

Related genera can be grouped in a more inclusive group called family

Families are grouped into order

Orders are grouped into classes

classes are grouped into phyla

Biologists group phyla can be assigned into six Kingdoms

1-Archaebacteria (unicellular prokaryotic cells without nuclei)

2-Eubacteria (bacteria)3-Protista (protozoa)

4-Fungi (Yeast)5-Planta (Complex multicellular

organisms, carry out photosynthesis)

6-Animalia (multicellular organisms that eat other organisms for nutrition)
