Color & Pattern
Deep rich green upper surface with lighter undersides. Slight yellowing along leaf margins and minor browning/necrosis near insect-damaged areas.
Venation Pattern
Pinnate venation with prominent central midrib and pale, yellow-green secondary veins arching toward the apex.

Leathery (coriaceous), semi-glossy adaxial (upper) surface with a slightly papery, smooth feel.
Description
This leaf comes from an avocado tree (Persea americana), a medium to large evergreen tree in the laurel family. The leaves are typically thick and leathery with aromatic foliage when crushed. The tree bears green to dark purple pear-shaped drupes containing a single large seed.
Key Features
Smooth entire margin, pale prominent pinnate veins, thick leathery texture, distinct aromatic scent when crushed, alternate spiral arrangement.
Habitat
Subtropical and tropical climates; prefers deep, well-draining, nutrient-rich soils with full sun exposure.
Geographic Range
Native to South-Central Mexico and Central America; widely cultivated in tropical, subtropical, and Mediterranean regions worldwide (e.g., California, Florida, Mexico, Chile, Israel).
Condition Notes
Fair condition overall. Shows minor mechanical or insect feeding damage along the upper left and lower right margins, along with mild marginal chlorosis/necrosis.
Interesting Facts
Avocado leaves contain essential oils that give them an anise-like scent when crushed. In Mexican cuisine, dried avocado leaves are used as a spice to flavor beans and stews.
Medicinal & Uses
Edible fruit is highly nutritious, rich in healthy fats and potassium. Leaves are used in traditional teas and culinary seasonings. Avocado oil is widely used in cosmetics and cooking.
Ecological Role
Provides shade and canopy cover; flowers attract bees and other nectar-feeding insects, while fruits support frugivorous birds and mammals in native habitats.
Similar Species
Bay Laurel (Laurus nobilis) has smaller, stiffer, aromatic leaves; Camphor tree (Cinnamomum camphora) has 3-nerved leaf bases and strong camphor scent.
Foraging Tips
Crush a fallen or freshly picked leaf to smell for the characteristic subtle anise or herbal laurel aroma. Look for trees with dense evergreen canopies and alternate leathery leaves.
Toxicity Warning
Moderately Toxic to many animals (dogs, cats, horses, birds, goats) due to the fungicidal toxin 'persin' present in leaves, bark, and seeds. Generally non-toxic to humans, though leaf tea should be consumed in moderation.
