In angiosperms, the receptacle or torus (an older term is thalamus, as in Thalamiflorae) is the thickened part of a stem (pedicel) from which the flower organs grow. A thallus. The thalamus is the short floral axis, with compressed nodes and internodes on which various floral leaves are inserted. Thalamus is the direct prolongation of the pedicel and is also called torus or receptacle. A flower can be classified into several groups on the basis of their number and the presentation of their whorls, symmetry, floral appendages, amongst many other things.

Flower has short or long flower stalk which is called pedicel. When a raspberry is picked, the receptacle separates from the fruit, but in blackberries, it remains attached to the fruit. Based on the position of calyx, corolla and androecium in respect of the ovary on thalamus (receptacle), the flowers can be described as Hypogenous, Perigynous or Epigynous. In context|botany|lang=en terms the difference between torus and thalamus is that torus is (botany) the end of the peduncle or flower stalk to which the floral parts (or in the asteraceae, the florets of a flower head) are attached; see receptacle while thalamus is (botany) the receptacle of a flower; a torus.

The receptacle (thalamus) : Variation of the Receptacle, Insertion of floral leaves on the thalamus The receptacle (thalamus). Floral architecture is a term which is not commonly used. A flower having only functional stamens and lacking functional carpels is called a staminate flower, or (inaccurately) male. The flower is commonly borne on short or long stalk called the pedicel (stalked or pedicellate flower). Morphology of Flower Characteristics Flower is highly condensed and modified reproductive shoot. See Wiktionary Terms of Use for details. In botany, the receptacle refers to vegetative tissues near the end of reproductive stems that are situated below or encase the reproductive organs.

The flowers in which the margin of the thalamus grows upward enclosing the pvary completely and getting fused with it , the other parts are located above flower Calyx Is the outermost whorl of the flower and its members are called the sepals. Whereas in some cases the calyx forms a cup shaped structure called calyx tube such as in wild rose. n thalamus Specifically, the optic thalamus; the thalamus of the optic nerve; the great posterior ganglion of the cerebrum, forming the lateral wall of the cerebral ventricle, and connected with its fellow by the middle commissure of the brain. In phycology, receptacles occur at the ends of branches of algae mainly in the brown algae or Heterokontophyta in the Order Fucales. An area of the brain that helps process information from the senses and transmit it to other parts of the brain. The terminal part of the axis of the flower is the receptacle or thalamus. The flower is the reproductive unit in the angiosperms. Flowers with bracts are called bracteate and those without bracts are called ebracteate. Receptacle (noun) A plug (typically by receiving the plug's supply portable appliances or equipment. They are specialised structures which contain the reproductive organs called conceptacles. These 4 whorls consisting of the accessory organs and the reproductive organs are set up in the formation of a stalk known as the receptacle or the thalamus. There are usually four whorls as Calyx (Sepals) Corolla (Petals) (electricity, US) A contact device installed at an outlet for the connection of an attachment plug and flexible cord to supply portable equipment or appliances.

When a flower is borne singly, the internode between the receptacle and the bract (the last leaf, often modified and usually smaller than the other leaves) is the peduncle. Under this … All the four parts develop in ascending order on the swollen end (the thalamus or receptacle or torus) of the floral axis or stalk, the pedicel. A bisexual flower has both androecium and gynoecium, while a unisexual flower has either androecium and gynoecium. In context|botany|lang=en terms the difference between receptacle and thalamus is that receptacle is (botany) the part of the flower stalk (peduncle or pedicel) to which the floral parts are attached; also torus while thalamus is (botany) the receptacle of a flower; a torus.
