Compound leaves may be pinnate with pinnae (leaflets) on both sides of a rachis (axis), or may be palmate with multiple leaflets arising from a single point. [1] Leaf structure is described by several terms that include: Bipinnate leaf anatomy with labels showing alternative usages A ternate compound leaf with a petiole but no rachis (or rachillae)
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 ...
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.
It is a deciduous tree growing to 15–25 m (rarely up to 50 m) tall, with a trunk diameter of up to 1 m belonging to Family Leguminosae and sub-family Caesalpiniaceaea. . The leaves are bipinnate, 30–60 cm long, with 16–20 pinnae, each pinna with 20–40 oval leaflets 8–25 mm long and 4–10 mm br
They are medium-sized deciduous trees growing to 10–20 m (33–66 ft) tall, with spirally arranged pinnate or bipinnate leaves.The flowers are small and yellow, produced in large branched panicles 20–50 cm (8–20 in) long.
They are trees, shrubs or lianas, which may be armed or unarmed. [36] Where they have spines, these are modified stipules. In some, prickles arise from the stem's cortex and epidermis. [37] The leaves are bipinnate or are modified to vertically oriented phyllodes. A few have cladodes rather than leaves. [38]
Gymnocladus species are very large, deciduous trees with bipinnate leaves. The greenish-white flowers only appear after long periods of warm weather. Very long legumes are formed that hang from the branches. The species of this genus are predominantly distributed endochorically.
The tree has thin, straight, light, grey spines in axillary pairs, usually in 3 to 12 pairs, 5 to 7.5 cm (3 in) long in young trees, mature trees commonly without thorns. The leaves are bipinnate, with 3–6 pairs of pinnulae and 10–30 pairs of leaflets each, tomentose, rachis with a gland at the bottom of the last pair of pinnulae.
