Shape
Oblong to elliptic leaflets with rounded or slightly pointed tips, arranged in pairs along a central axis (rachis)
Margin
Entire to very finely crenate or serrulate (finely toothed)

Alternate arrangement on the twig, though the leaflets themselves are oppositely or sub-oppositely arranged along the rachis
Venation
Pinnate venation with a central midrib and fine secondary veins branching out, though veins are subtle and relatively indistinct on the small leaflets
Key Features
Finely textured pinnately or bipinnately compound leaves with small leaflets, often accompanied by branched, sharp woody thorns on the trunk and branches in wild-type trees, and large flattened seed pods
Description
The Honey Locust is a medium to large deciduous tree recognized for its open, spreading crown, delicate fine-textured foliage, and often formidable branched thorns on the trunk and branches (though thornless cultivars are common in landscaping). The tree produces fragrant greenish-yellow flowers in spring followed by large, twisted, dark brown leathery pods that contain sweet pulp.
Habitat
Typically found in moist, rich soils along streams and floodplains, but remarkably adaptable to dry uplands, urban environments, and poor soils; thrives in full sun
Native Range
Native to central North America, from the Ohio and Mississippi river valleys west to the Great Plains, and widely planted as an urban shade tree across North America and parts of Europe
