What is Corymbose raceme?
Corymbose raceme – As the name suggests, it is a kind of amalgamation of the 2 above-mentioned inflorescences. The younger flowers (top part) resemble corymb (the younger few flowers are at the same level because of elongated pedicels). Spadix – It is a special type of spike racemose inflorescence.
What is Corymbose inflorescence?
Corymb is a botanical term for an inflorescence with the flowers growing in such a fashion that the outermost are borne on longer pedicels than the inner, bringing all flowers up to a common level. Flowers in a corymb structure can either be parallel, or alternate, and form in either a convex, or flat form.
What plants have raceme inflorescence?
In a raceme a flower develops at the upper angle (axil) between the stem and branch of each leaf along a long, unbranched axis. Each flower is borne on a short stalk, called a pedicel. An example of a raceme is found in the snapdragon (Antirrhinum majus). A raceme of lily of the valley (Convallaria majalis).
Is a raceme of cymes?
A raceme in which the single flowers are replaced by cymes is called a (indefinite) thyrse. The secondary cymes can be of any of the different types of dichasia and monochasia. A botryoid in which the single flowers are replaced by cymes is a definite thyrse or thyrsoid. Thyrses are often confusingly called panicles.
What is an example of Cymose inflorescence?
What is Cymose Inflorescence? Ans. In this type of inflorescence, the young flower buds are at the bottom, and the older ones are at the top. Some cymose inflorescence examples are night jasmine, Drosera, common European elder etc.
What is racemose and Cymose?
Racemose refers to a type of flowering shoot in which the growing region at the tip of the flower stalk continues to produce new flower buds during growth while cymose refers to a type of flowering shoot in which the first-formed flower develops from the growing region at the top of the flower stalk.
What are the types of Cymose?
There are four main types of cymose inflorescence:
- Monochasial cyme.
- Dichasial cyme.
- Polychasial cyme.
- Cymose capitulum.
What is the difference between two types of inflorescence?
Inflorescence is divided into two main types: Racemose: In racemose types of inflorescence, the main axis grows continuously and flowers are present laterally on the floral axis. Cymose: In the cymose type of inflorescence, the main axis does not grow continuously. A flower is present terminally on the main axis.
What kind of inflorescence is a corymb plant?
Common types of inflorescences among the angiosperms. In inflorescence: Indeterminate inflorescence. A corymb is a raceme in which the pedicels of the lower flowers are longer than those of the upper flowers so that the inflorescence has a flat-topped appearance overall, as in hawthorn ( Crataegus ).
Which is raceme has a flat topped inflorescence?
In inflorescence: Indeterminate inflorescence. A corymb is a raceme in which the pedicels of the lower flowers are longer than those of the upper flowers so that the inflorescence has a flat-topped appearance overall, as in hawthorn ( Crataegus ).
What kind of inflorescence is a racemose flower?
Racemose inflorescence – It is of two types. Typical Raceme – Unbranched, elongated peduncle bearing pedicellate or stalked flowers acropetally. Example – Delphinium, Linaria etc. Corymb – All the acropetally arranged flowers come to lie at the same level due to slight shortening or elongation of peduncles of lower flowers.
What kind of inflorescence is a cymose flower?
Cymose Inflorescence: Cymose inflorescence is the name of determinate or definite inflorescence in which the tip of the main axis terminates in a flower and further growth continues by one or more lateral branches which also behave like the main axis (Fig. 5.75). The arrangement of flowers is either basipetal or centrifugal.
