Study Notes
Medicinal Plants Lecture Notes
- Lecture 8 Topics: Anatomy (Lectures 1-7), Dusting powders, Taxonomy (Lecture 6), Physiology, Introduction to Pharmacognosy
- Taxonomy: The science of describing, naming, and classifying organisms. Organism grouping is based on similarities. Scientific names are essential because the same common name can be used for different plants in different regions. Latin is the language used for scientific classification.
- Binomial System: A two-part naming system for scientific names. The first part is the genus (always capitalized). The second part is the species (never capitalized). Both words are italicized or underlined. Example: Ocimum africanum (Genus: Ocimum, Species: africanum)
-
Family Classification (Examples):
- Compositae/Asteraceae: Sunflower family
- Umbelliferae/Apiaceae: Carrot or Parsley family
- Cruciferae/Brassicaceae: Mustard or Cabbage family
- Labiatae/Lamiaceae: Mint family
- Gramineae/Poaceae: Rice, maize, wheat family
- Leguminosae/Fabaceae: Bean or pea family
-
Scientific Classification of Syzygium aromaticum L. (Clove):
- Kingdom: Plantae
- Clade: Tracheophytes
- Clade: Angiosperms
- Clade: Eudicots
- Clade: Rosids
- Order: Myrtales
- Family: Myrtaceae
- Genus: Syzygium
- Species: aromaticum
- Binomial name: Syzygium aromaticum (L.) Merr. & L.M.Perry (Author: L.)
- Synonyms: Various (e.g., Caryophyllus aromaticus, Eugenia aromatica)
- Example of Monocot: Maize plant (Note: Monocot plant features include parallel leaf venation and a single cotyledon)
- Example of Dicot: Mentha plant (Note: Dicot plant features include net-like leaf venation and two cotyledons)
-
Monocot Families:
- Gramineae (Poaceae): (Oryza sativa (Rice), Triticum aestivum (Wheat)): Caryopsis fruit, parallel leaf venation
- Zingiberaceae: (Ginger, Curcuma (turmeric)): Rhizomatous and sympodial stems
- Liliaceae: (Squill, Colchicum): Food stored in a bulb or rhizome, basal and cauline leaves
- Dicot Families (Examples): Umbelliferae (Apiaceae), Solanaceae (Potato, Tomato), Compositae (Asteraceae), Leguminosae (Fabaceae), Lamiaceae (Mint family)
- Plant Origins (Example): The dried leaves of Mentha piperita (Family: Lamiaceae)
- Species Name Considerations: Morphological characteristics, Geographic source (e.g., Olea europea, Cannabis indica), Special indications (e.g., Quillaia saponaria)
- Old Classification (Two Kingdoms): Animalia and Plantae (Linnaeus 1758), Separating subkingdoms like Thallophyta and Embryophyta
- New Classification (Five Kingdoms): Whittaker's classification, including Monera, Protista, Fungi, Animalia, and Plantae (1920-1980 – Important dates)
- Plant Parts:
- Plant Kingdom Types
- Angiosperm: Flowering plants, stems with xylem tissue (vessels), ovules and seeds enclosed in ovaries(fruits), closed carpels/fruits
- Gymnosperm: Cone-bearing plants, stems with tracheids, ovules and seeds exposed/unenclosed
- Quiz Questions: Identification (monocot vs. dicot), stomata type, plant family, etc.
