leaf tip: Tailed at the apex cirrus, cirrate: leaf tip: Having a rachis that extends beyond the leaf blade or leaflets into a long whip-like extension or cirrus (common in climbing palms); antonym: ecirrate: cordate, cordiform: cordatus: whole leaf or base: Heart-shaped, with the petiole or stem attached to the notch cuneate: cuneatus: leaf base
Leaf morphology: Shape, margin and venation. Leaf Parts: – A complete leaf is composed of a blade, petiole, and stipules, but in many plants one or more might be lacking or highly modified. Blade – see lamina. Lamina – the flat and laterally-expanded portion of a leaf blade. Leaflet – a separate blade, among others, of a compound leaf

Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally above ground and specialized for photosynthesis.Leaves are collectively called foliage, as in "autumn foliage", [2] [3] while the leaves, stem, flower, and fruit collectively form the shoot system. [4]
The leaf apex can be acute, obtuse, or rounded, often with a mucronate tip. The base of the leaf is typically obtuse to cordate, sometimes rounded. The leaf margin is thickened and may appear flat or slightly rolled back. Most leaves are observed to be entire, although some may possess 1-3 pairs of sharp mucronate teeth near the apex.
The leaf shapes vary from lamina ovate to elliptic. The apex of the leaf also vary from acuminate to cuspidate and base of the leaf is attenuate with broad glossy hairs along midrib and veins. Flower are arranged in racemoid head that are 3 cm long, peduncle is 0.5–23 mm long, winged, and vary from being hairy to hairless.
These are emergent trees that can attain height about 50 m and girth up to 2 m. Leaves are simple and show alternate phyllotaxy. Mostly seen as clustered towards the end of branches. They are pubescent when young and glabrous when mature. Size: 8-20 × 6-10 cm. Leaf shape can be described as broadly elliptic or ovate. Leaf apex is shortly ...
