Some apply it to the leaflets of a pinna, especially the leaflets of bipinnate or tripinnate leaves. [7] Others also or alternatively apply it to second or third order divisions of a bipinnate or tripinnate leaf. [8] It is the ultimate free division (or leaflet) of a compound leaf, or a pinnate subdivision of a multipinnate leaf.
Chart illustrating leaf morphology terms. The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1]
(of a compound leaf) Having precisely two leaflet s, usually in a symmetrical pair, e.g. a leaf of Colophospermum mopane. Compare jugate lobed leaf, e.g. most species of Bauhinia. bifusiform Fusiform with a pinch in the middle. bilabiate Having two lips, e.g. the form of the petal s in many irregular flowers. bilateral 1.
Pentaclethra macrophylla, also known as the African oil bean, tree is a large size tree with long bipinnate compound leaves that is endemic to West and Central Africa. It is within the family Fabaceae. Seeds of the species are prepared and fermented to make Ugba, a soup condiment in Nigeria.
Burkea africana is a tree growing from 4 to 20 meters high. [1] Leaves are bipinnately compound, silvery pubescent or glabrescent. Flowers are creamy white, fragrant and in pendulous racemes of up to 300 mm in length.
A simple leaf has an undivided blade. However, the leaf may be dissected to form lobes, but the gaps between lobes do not reach to the main vein. A compound leaf has a fully subdivided blade, each leaflet of the blade being separated along a main or secondary vein. The leaflets may have petiolules and stipels, the equivalents of the petioles ...
Meadow-rue leaves are alternate, bipinnately compound, and commonly glaucous blue-green in colour. [citation needed]The flowers are small and apetalous (no petals), but have numerous long stamens, often brightly white, yellow, pink or pale purple, and are produced in conspicuous dense inflorescences.
The leaves are alternate, bipinnately compound leaves; with an ovate shape and a pinnate venation, they have a green color which turns yellow in fall, leavelets measuring between 5–10 cm long. The flowers are small and yellow with a touch of red at the base, with four petals, produced in large branched panicles that are 20–50 cm long. They ...
