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.
The shrub or small tree has a dense rounded crown, and usually reaches between 1 and 3 metres in height. The grey bark turns brown and eventually blackish as the tree ages. The bipinnately compound leaves measure some 25 cm long, and bear 4 to 8 pinnae with 12 to 23 pairs of leaflets each. [2]
Its leaves are bipinnately compound, up to 5 - 9 of mostly opposite pinnae and each pinnae having 12 - 24 leaflets. Leaflets alternate, can reach 2 cm long and 1 cm wide, they are narrowly oblong to elliptic in shape and rounded at both the apex and the base. [ 5 ]
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.
The bipinnately compound leaves are up to 15 centimetres (5.9 in) long. Flowers of the Dichrostachys cinerea are characteristically arranged in bicoloured cylindrical spikes that resemble Chinese lanterns, 6 to 8 centimetres (2.4 to 3.1 in) long and fragrant. [9]
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.
The leaves are bipinnately compound, with one or two pinnae pairs, and 10–26 leaflets per pinna. The petioles are also prickly. Pedunculate (stalked) pale pink or purple flower heads arise from the leaf axils in mid-summer with more and more flowers as the plant gets older. A single flower survives for less than a day, and usually dies ...
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]
