Such whorl of bracts is called involucre. Usually the lemma also known as inferior palea bears a long awn as an extension of the mid-rib at the apex or back. Typical examples, are—Ocimum, Coleus, Mentha, Leucas, etc. or tubular floret. Ray floret or ligulate floret.The flower and inflorescence are In this type of inflorescence the growth of the main axis is ceased by the development of a flower at its apex, and the lateral axis which develops the terminal flower also culminates in a flower and its growth is also ceased. This type of inflorescence is found in Acacia, Mimosa and Albizzia. The flowers may be pedicellate (stalked) or sessile (without stalk). It bears sessile or sub-sessile flowers on it.
young flowers at baseInflorescences in which both This type of opening of flowers is known as centrifugal. The main axis of the inflorescence together with the latest axes, if present, is termed as the peduncle. Examples are sunflower florets, Sisyrinchium.

But an inflorescence is a group of flowers arising from a branched or Example - mustard. Based on the symmetry of the flowers can be described in to following types: 1. The leaves of most monocotyledons lack petioles. Zygomorphic: …

An example is Achyranthes. In the former case it becomes a compound raceme and in the latter case it becomes a compound cymose inflorescence. In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts which have no stalk. A flower without a stalk or pedicel is called sessile and a flower having a stalk is called pedicellate.
