Oddly pinnate, pinnatifid leaves (Coriandrum sativum, coriander or cilantro) Partial chlorosis revealing palmate venation in simple leaves of Hibiscus mutabilis
Leaf Parts: – A complete leaf is composed of a blade, petiole, and stipules, but in many plants one or more might be lacking or highly modified. Blade – see lamina. Lamina – the flat and laterally-expanded portion of a leaf blade. Leaflet – a separate blade, among others, of a compound leaf
Automated species identification is a method of making the expertise of taxonomists available to ecologists, parataxonomists and others via digital technology and artificial intelligence. Today, most automated identification systems rely on images depicting the species for the identification. [1]
Quercus chrysolepis, commonly termed canyon live oak, canyon oak, golden cup oak or maul oak, is a North American species of evergreen oak.Its leaves are a glossy dark green on the upper surface with prominent spines; a further identification arises from the leaves of canyon live oak being geometrically flat.

Leaf area index (LAI) is a dimensionless quantity that characterizes plant canopies. It is defined as the one-sided green leaf area per unit ground surface area (LAI = leaf area / ground area, m 2 / m 2) in broadleaf canopies. [1] In conifers, three definitions for LAI have been used: Half of the total needle surface area per unit ground ...
