Coca Seed

Erythroxylum Coca & Novogranatense — Botanical Reference Seeds for Research

Erythroxylum coca and Erythroxylum novogranatense are two closely related species with high botanical and ethnobotanical significance. These specimens are provided for scientific research, taxonomic study, and educational purposes. Each sample is documented and archived for reliable reference in comparative morphology and ethnobotanical investigations.

Taxonomy Overview

Within the Erythroxylum genus, several taxa display distinct morphological traits:

• E. coca var. coca – native to humid Andean forests
• E. coca var. ipadu – adapted to Amazonian regions
• E. novogranatense var. novogranatense – grows in dry South American areas
• E. novogranatense var. truxillense – adapted to arid Peruvian valleys

Phylogenetic studies indicate that E. coca var. coca represents the ancestral form, while novogranatense variants evolved through regional adaptation.

Ecological & Growth Conditions

Propagation & Planting (Research Context)

Seed specimens are used for botanical observation and reference. Researchers typically document germination and morphology under controlled lab or greenhouse conditions:

• Seeds can be pre-soaked for observation purposes.
• Use light, well-draining media (e.g., peat + perlite mix) in controlled studies.
• Maintain consistent temperature and humidity for accurate morphological comparison.

Identification Guide

Key morphological differences assist in taxonomic classification:

• E. coca: larger elliptical leaves, broader mid-section
• E. novogranatense: smaller, narrow leaves with parallel venation along the central vein

Scientific & Educational Applications

• Taxonomic research and comparative morphology
• Ethnobotanical and historical plant studies
• Herbarium collections and botanical documentation
• Academic projects and laboratory experiments
