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 palmately compound, with 3-9 leaflets or it can be simple, leaves are deeply lobed when mature and tend to have a leathery glabrous to glabrescent upper surface, its young leaves tend to be tomentose; leaflets are 6-30 cm long and 2-18 cm wide. Leaflets are obovate to elliptical in outline, the margin is commonly entire to ...
Their leaves are typically grouped in umbrella-shaped arrangements at the tips of long erect branches. The leaves are carried on long petioles, and have conspicuous stipules. The leaves are very variable in shape, often palmately compound ( cf. subgenus Paniculata Strey ) [ 2 ] with leaflets likewise variable in shape, but also simple or palmate.
Composed of several parts, e.g. a leaf composed of multiple leaflet s, a gynoecium composed of multiple carpel s, or an inflorescence made up of multiple smaller inflorescences. compound palmate Having leaflet s that radiate from a central point (usually at the top of a petiole), like spread-out fingers radiating from the palm of a hand ...
Palmately compound leaf of hemp. A leaflet (occasionally called foliole) in botany is a leaf-like part of a compound leaf. [1] Though it resembles an entire leaf, a leaflet is not borne on a main plant stem or branch, as a leaf is, but rather on a petiole or a branch of the leaf. [2]
Argyrodendron actinophyllum is a tree that typically grows to a height of 50 m (160 ft) with prominent buttress roots and dark grey or very dark grey bark. The leaves are palmately compound with 5 to 9 lance-shaped leaflets, sometimes the narrower end towards the base, 100–180 mm (3.9–7.1 in) long and 15–50 mm (0.59–1.97 in) wide on a petiole 30–50 mm (1.2–2.0 in) long.
Because each leaflet can appear to be a simple leaf, it is important to recognize where the petiole occurs to identify a compound leaf. Compound leaves are a characteristic of some families of higher plants, such as the Fabaceae. The middle vein of a compound leaf or a frond, when it is present, is called a rachis. Palmately compound
Members of the alliance are morphologically similar, with an elongated fleshy rhizome and either ternate or palmately compound leaves. [5] The vegetative parts of this plant, which can reach 20–40 cm, arise from a segmented rhizome. The leaves are on long petioles, deeply and palmately dissected into five segments with large "teeth" on the ...
