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]
Young plants are hairy on the stems and leaves, while mature plants have scrambling rope-like branches that are armed with recurved thorns or conical knobs. [2] The alternate and bipinnately compound leaves consist of 5 to 13 paired primary leaflets (pinnae), and 7 to 16 paired leaflets per pinna. [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.
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 ]
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]
(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.
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 ...
