Guide to Botanical Explorers Throughout History

Botanical exploration is the systematic study, documentation, and collection of plants. It has been a pursuit motivated by curiosity, medicine, commerce, agriculture, and colonial ambitions. Over centuries, explorers risked extreme climates, disease, and political instability to expand knowledge of the plant kingdom. Their work shaped modern botany, ecology, horticulture, and pharmacology.

Legacy: Instrumental in transforming Kew Gardens into a global center of botanical research.

3.2. Taxonomy and Classification

Carl Linnaeus (1707–1778)

Nationality: Swedish
Contributions:
- Developed binomial nomenclature (genus + species) in Species Plantarum (1753).
- Encouraged global plant collection by students and explorers.
Legacy: Linnaeus’ classification system is still the foundation of modern botanical taxonomy.

Alexander von Humboldt (1769–1859)

Nationality: Prussian
Expeditions: South and Central America, including Venezuela, Colombia, and Mexico.
Contributions:
- Studied plant distribution relative to climate, altitude, and geography.
- Advocated for scientific observation and ecological thinking.
Legacy: Father of plant geography and ecological science.

4. 19th Century: Global Botanical Expeditions

The 19th century marked the golden age of plant exploration, often tied to imperial ambitions and global commerce.
