The apex is the tip of the leaf blade. Acuminate apices have a long, slender, sharp point, with a terminal angle less than 45 degrees, and straight to convex sides. Acute apices have a sharp-pointed tip, with a terminal angle between 45 and 90 degrees, and straight to convex sides.

Leaf apex is the tip or protruding part of the leaf. The leaf apices can vary in shapes and sizes in different plants. Let us look at the different types of leaf apices found in plants.

Leaf Apices (The Leaf Apex) The leaf tip, or apex, is used to help describe the leaf. There are many species with leaves that differ only slightly by shape, but can be readily distinguished by their apices.

Leaves are lateral determinate structures formed in a predictable sequence (phyllotaxy) on the flanks of an indeterminate shoot apical meristem. The origin and evolution of leaves in vascular plants has been widely debated.

The leaf apex refers to the tip or end of a leaf. It is the terminal point of the leaf blade, opposite to the leaf base. They are classified as acuminate, acute, obtuse, rounded, emarginate, mucronate, and cuspidate, etc.

This document defines and illustrates various types of leaf apices: 1. It defines 10 different types of leaf apices including acute, obtuse, emarginate, caudate, and aristate. 2. For each type of leaf apex, it provides a textual definition describing the shape and features. 3.

(e) Leaf Apices: The apex of the leaf may be one of the following kinds: 1. Obtuse: Rounded tip i.e. Banyan. 2. Acute: When it is pointed to form acute angle, but not stiff i.e. Hibiscus. 3. Acuminate: Pointed tip with much elongation, Peepal.

The purpose of this tutorial is to introduce basic botanic terminology to students using verbal and visual examples to help describe and learn woody plant material. Explore the various helpful leaf identification features. Start by choosing one of the categories below.

Jul 16, 2018 · A stipule is the outgrowth of the hypopodium or leaf base. Ordinarily a stipule is a tiny structure growing on both sides of a leaf at its base, but in many cases they are large and conspicuous or variously modified to discharge special functions.

Emarginate Leaf Apex. The apex of the leaf is notched downward (towards the petiole) at the midvein. In the case of the Five-leaved Akebia, every leaflet is notched on this compound leaf.
