A group of related plant families, classified in the order in which they are thought to have developed their differences from a common ancestor
Family
A group of related genera
Genus
A group of closely related species
Species
The most specific level of classification, referring to a group of organisms that can interbreed and produce fertile offspring
Plant classification process
1. Sort and classify organisms based on similarities and differences
2. Assign English and Latin names for different divisions
Theophrastus was a Greek philosopher and naturalist, often called the "Father of Botany"
Theophrastus was a pupil of Aristotle and was the first person to publish a classification of plants
Theophrastus classified plants based on form (herbs, shrubs, trees; annuals, biennials, perennials)
Herbs
Fragrant leaves or other parts of certain plants, called "damong-gamot" in the Philippines. Examples: mint, basil, oregano, parsley, kinchay, spinach baby leaf
Shrubs
A type of plant that typically have multiple woody stems and are smaller than trees. Examples: roses, pomegranate, jasmine, lemon, china rose
Trees
Woody perennial plants, having a single stem or trunk growing to a considerable height with lateral branches. Examples: mango, papaya, ylang ylang, banaba, narra, salingbobog
Carolus Linnaeus was the first person to propose an orderly system for classifying organisms
Linnaeus developed the Binomial System of Naming Plants in 1753
Binomial name
The scientific name of a plant composed of two Latin names, a genus and a species
Linnaeus is called the "Father of Taxonomy"
Plant classification system
Sorts and classifies organisms based on similarities and differences
Features both English and Latin names for different divisions

Includes over 275,000 plant species
Phylum Tracheophyta
Vascular plants, over 250,000 species

Flowering plants, over 235,000 species
Order Rosales
Roses and their allies, over 18,000 species
Family Rosaceae
Over 3,500 species

Species Rosa gallica
Moss rose
Vascular plants have tubelike structures that carry water, nutrients, and other substances, examples are ferns, gymnosperms, and flowering plants
Non-vascular plants do not have tubelike structures and use other ways to move water or substances, examples are algae, mosses, liverworts, and hornworts
Angiosperms
Plants which produce flowers
Gymnosperms
Plants which don't produce flowers
Dicotyledons (dicots)
Plants with two seed leaves, examples: papaya, tomato, rose, sunflower
Monocotyledons (monocots)
Plants with one seed leaf, examples: coconut, ginger, orchids
Cotyledon
A part inside a seed that looks like a small leaf, which the developing plant uses as a store of food
Monocot seeds produce a single leaf when they germinate, while dicot seeds produce two seedleaves
Monocots have parallel leaf veins, while dicots have net-like leaf veins
Monocots have vascular bundles arranged in a ring, while dicots have vascular bundles located in the middle
Monocots have clearly visible internodes on the stem, while dicots have internodes that cannot be seen clearly
The Philippines has a total of 13,500 plant species, with 1,500 being medicinal plants and 3,500 being indigenous
120 Philippine medicinal plants (12.5%) have been validated for safety and efficacy
10 Philippine medicinal plants have been promoted by the Department of Health since 1993 and the Philippine Institute for Traditional & Alternative Health Care since 1997
