An inflorescence, in a flowering plant, is a group or cluster of flowers arranged on a stem that is composed of a main branch or a system of branches. [1] An inflorescence is categorized on the basis of the arrangement of flowers on a main axis and by the timing of its flowering (determinate and indeterminate). [2]
[1]: 37 It is also possible to represent (partial) inflorescences by diagrams. A substantial amount of information may be included in a good diagram. It can be useful for flower identification or comparison between angiosperm taxa. Paleontologists can take advantage of diagrams for reconstruction of fossil flowers. Floral diagrams are also of ...

3. Sterile flower s, e.g. in Muscari and Leopoldia, at the apex of some inflorescences. 4. A tuft of hairs at the base of some flowers, e.g. in Pfaffia gnaphalioides. 5. A tuft of hairs at the apex or base of some spikelet s. 6. An axil tuft of hairs in inflorescences in some Poaceae, e.g. in Eragrostis comata. commercial name
The meristem can be defined as the tissue or group of plant tissues that contain undifferentiated stem cells, which are capable of producing any type of cell tissue.Their maintenance and development, both in the vegetative meristem or the meristem of the inflorescence is controlled by genetic cell fate determination mechanisms.
This type of inflorescence is called spikelet. The flowers can be hermaphrodites or unisexuals and present a rudimentary perianth of 2 or 3 pieces, the lodiculae or glumellulae. These lodicules are the organs that, when they become turgid, determine the opening of the antecio or floral box during flowering, allowing the feathery stigmas and the ...
