Determinate simple inflorescences are generally called cymose. The main kind of cymose inflorescence is the cyme (pronounced / s aɪ m /), from the Latin cyma in the sense 'cabbage sprout', from Greek kuma 'anything swollen'). [9] [10] Cymes are further divided according to this scheme: Only one secondary axis: monochasium
The function of these flowers is to specialize, within a group of flowers that are perfect, in attracting pollinating insects to the inflorescence. Such flowers, called neutral or asexual, are usually arranged on the periphery of the inflorescence and can be observed, for example, in many species of the compositae family, such as the daisy ...

Guard cell – one of the paired epidermal cells that control the opening and closing of a stoma in plant tissue. Heartwood – the older, nonliving central wood of a tree or woody plant, usually darker and harder than the younger sapwood. Also called duramen. Herbaceous – non-woody and dying to the ground at the end of the growing season.
In botany, an umbel is an inflorescence that consists of a number of short flower stalks (called pedicels) that spread from a common point, somewhat like umbrella ribs.The word was coined in botanical usage in the 1590s, from Latin umbella "parasol, sunshade". [1]
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. A corymb has a flattish top with a superficial resemblance towards an umbel , and may have a branching structure similar to a panicle .
Flower differentiation is a plant process by which the shoot apical meristem changes its anatomy to generate a flower or inflorescence in lieu of other structures. Anatomical changes begin at the edge of the meristem, generating first the outer whorls of the flower - the calyx and the corolla, and later the inner whorls of the flower, the androecium and gynoecium.
