Epigynous вЂ“ Ovary is inferior and other whorls are arranged above the ovary as thalamus envelops the ovary e.g. Perigynous вЂ“ Ovary is present in the centre and other floral whorls are arranged on the rim of the thalamus as thalamus is flat and disc like e.g. Hypogynous вЂ“ Ovary occupies more space as thalamus is conical in shape e. Unisexual вЂ“ Any one essential floral whorl is absent in the flowerДЎ. Bisexual flower вЂ“ Both the essential floral whorls are present in the flowerД¤. Incomplete flower вЂ“ Any one whorl is absent in the flowerДЈ. Complete flower вЂ“ All four whorls are present in the flowerДў. Components of whorls are concentrically arranged on a thalamus.Д¬alyx and corolla do not participate in the process of reproduction but helps in protection and attraction and hence they are called as accessory floral whorls.ДЄndroecium and gynoecium takes part in the process of reproduction and hence called as essential floral whorls.ДЇlowers are classified based on the whorls present in it or on the position of the ovary present in gynoecium.ДЎ. Thalamus - An expanded tip of the pedicel. Gynoecium вЂ“ Present at the inner most side of the androecium and made up of carpel. Pollen grains are produced within anther.Д¤. Filament and anther are joined through connective. Each stamen contains filament, anther and a connective. Androecium вЂ“ Present inside the corolla and made up of stamens. It attracts insects for pollination due to its color.ДЈ. Petals are different in color and shapes and protects the other whorls present inside it. Corolla вЂ“ Present inside the calyx and made up of petals.

Sepals are green and protect the other whorls of the flower.Дў. Calyx вЂ“ Outermost whorl of the flower made up of sepals. A typical flower contains four whorls (calyx, corolla, androecium and gynoecium) and thalamus.ДЎ. All members of the arum family (Araceae) have a spadix inflorescence.A shoot is modified for sexual reproduction, and then it is called as flower. All members of the sunflower family (Asteraceae) have heads, including chrysanthemums, zinnias, marigolds, and dandelions. For example, nearly all members of the carrot family (Apiaceae) have compound umbels. Some types of inflorescences characterize different groups of plants. Spadix: The flowers have no pedicels and are attached along the length of the thickened or fleshy peduncle, which is enveloped by a conspicuously colored bract called a spathe (example: philodendron, anthurium). This type of inflorescence is also referred to as ament. The flowers are usually very small and fall as a group. The youngest flowers in any cluster occur farthest from the tip of the peduncle (example: chickweed).Д¬atkin:The flowers have no pedicels, are unisexual (either staminate or pistillate), and are at tached along the length of the peduncle (examples: hazelnut, willow, birch, walnut). This type of inflorescence is also referred to as capitulum.Д¬yme: The flowers with pedicels are located at the ends of the peduncle and lateral branches as well as along the length of the lateral branches. Head: The flowers do not have pedicels, and they all cluster tightly on the expanded tip of the peduncle (examples: sunflower, daisy, marigold). A compound umbelis formed when the peduncle produces branches that end at approximately the same level, forming a flat top, and the ends of these branches arise from a common point (examples: carrot, dill, parsley). Umbel: The flowers are with pedicles, which are all attached at about the same point at the end of the peduncle this is specifically called a simple umbel (examples: onion, geranium, milkweed). Panicle: The flowers are with pedicels, which are attached along the branches arising from the peduncle of the inflorescence (examples: oats, rice, fescue).Д¬orymb: The flowers are with pedicels of unequal length, which are attached along an unbranched, elongate peduncle, forming a flattopped inflorescence (examples: hawthorne, apple, dogwood).

The oldest flowers are at the base of the inflorescence and the youngest at the apex. Raceme: The flowers are with pedicels of about the same length, which are attached along the elongate and unbranched peduncle of the inflorescence (examples: lily of the valley, snapdragon, mustard, currant). Spike: The flowers, which are with a very short or with no pedicel, are attached along the elongate and unbranched peduncle of the inflorescence (examples: plantain, spearmint, tamarisk). Some of the common types of inflorescences are as follows: The arrangement of pedicels on a peduncle characterizes different kinds of inflorescences. It mayalso bear numerous smaller stalks called pedicels, each with a flower at its tip. An inflorescence has one main stalk, or peduncle.

Flowers may be solitary, or they may be grouped together in an inflorescence, a cluster of flowers.
