In the flowering period, the inflorescence axis of the top growth to continue upward, new buds, opening sequence is the base of the spent inflorescence open, and then turn to the top of the opening, or from the edge to the center opening, said that unlimited inflorescence inflorescence. Include: racemes corymbose, umbel, spikes, catkins inflorescence, spadix, capitulum, hidden head inflorescence, panicle, umbel compound, compound corymbs, complex spike inflorescence. Flowering period, the floral axis may continue to elongate and continuous generation of new inflorescence bracts and flower buds. Among them, the floral axis as the long column, and the flowers opening sequence is the base of the rachis, flowers bloom, and then advance to the top of the order; floral axis was shortened coils, each flower was a plane or spherical dense, the flowering sequence is first from the edge of the flower, and then turn to the center open. Raceme rachis longer than branches, many of its students on the flower stalk, the flower stalk, roughly equal to the length of the flowering sequence from the bottom up. Such as Wisteria, Chinese cabbage, rape, orchids, the inflorescence. A deformation of corymbose racemes. Unlike raceme inflorescence is that of varying lengths of the flower stalk, the lower longest flower stalk, the more recent Department of flower stalk flower axis shorter, the result that almost the entire inflorescence flowers arranged in a plane. Order flowers from outside to inside. Such as pear, apple, cherry, etc. inflorescence. Umbel floral axis shortening, most flowers grow from the top of the floral axis, radiating. The flower stalks roughly equal length, arranged in the inflorescence spherical. Order flowers from outside to inside. Such as Radix, ginseng, primrose, etc. inflorescence. Rachis erect spikes up, on which the students spend the majority of the sexes sessile. Such as taxi, verbena, etc. inflorescence. Catkins soft inflorescence rachis, the majority of its students on a sessile or with a short handle of the unisexual flowers (male or female flowers), flowers without perianth or involucre, inflorescence flexible, pendulous or erect, often after flowering, the inflorescence with the loss. Such as poplar, willow inflorescence; oak, hazel and other male inflorescence. Spadix rachis erect, fleshy and succulent, the majority of its students on a single floret of sessile. Such as corn, cattails, the female inflorescence. Some spadix are often outside the package has a large bract, the shape of corolla, quite beautiful, known spathe, it is also known as the Buddha of such flame spadix inflorescence. Such as Arisaema, Pinellia, calla lily flower and so on. Capitulum rachis extremely shortened and extended, full-width was head shape, on which the students spend the majority of sessile, the bracts of involucre often integrated, such as chrysanthemum, dandelion, sunflower, etc. inflorescence. Implicit in particular mast head inflorescence rachis, depression was cystic, with a small hole at the top only with the outside world, many sessile flowers born in the Depression of the cavity with walls, flowers unisexual, male flowers located in the inner wall of the upper part of the female distribution the lower part of the wall, from the outside, but not all of the flowers almost hidden, so named, such as fig inflorescence. Panicle rachis branching, to 1 per 1 sprig from racemes, the inflorescence racemes composed of many small, it is also known as complex raceme. Such as cloves, rice, South Tianzhu, etc. inflorescence. Compound umbel floral axis length of the top clusters of equal number of branches, each branch and from 1 to 1 umbel. Such as carrots, fennel, etc. Peucedanum inflorescence. Compound corymbs floral axis aligned with corymbose branches, each one into a branch and from corymbose. Plant inflorescence flower pollination. Complex spike rachis branch 1 or 2, each branch from 1 to 1 spike. Such as wheat, barley and the inflorescence.

Definition of infinite inflorescence
无限花序定义
无限花序定义
Unlimited inflorescence (indefiniteinflorescence), also known as infinite Highlights racemes, which is characterized by the main axis of inflorescence in flowering period, can continue to grow upward elongation, the continuous generation of bracts and flower buds, like uniaxial branches, so also called single-axis inflorescence. The opening sequence of each flower is the base of the rachis, flowers bloom, and then advance to the top of the order, and then click open. If you shorten the rachis, each flower was a plane or spherical dense when the order is to start with the edge of flowering, and then turn to the central opening.

Simple inflorescence
1, raceme (raceme) Rachis single, long, bottom-up followed by the birth to the flower stalk, the flower stalk, roughly equal to the length of the flowering sequence from the bottom up, such as wisteria, shepherd's purse, rape flowers. 2, the spike (spike) Rachis are especially large, cystic depression was only there a hole in the top and the outside world, many sessile flowers born in the Depression of the cavity with walls, flowers unisexual, male flowers located in the upper wall, located in the inner wall of female flowers the lower part, from the outside, but not all of the flowers almost hidden, so named, such as fig inflorescence. Such as Gramineae, Cyperaceae, Amaranthaceae and Polygonaceae many plant species have spikes. 3, catkins (catkin) Soft floral axis, the majority of its students on a sessile or with a short handle of the unisexual flowers (male or female flowers), flowers without perianth or involucre, inflorescence flexible, pendulous or erect, often after flowering, the inflorescence with the loss. Such as poplar, willow inflorescence; oak, hazel and other male inflorescence. 4 corymbs (corymb) Also known as flat-topped racemes, the racemes of deformation is different from the racemose inflorescence is that different lengths of the flower stalk, the lower longest flower stalk, the more recent Department of flower stalk flower axis shorter the result that almost the entire inflorescence flower arranged in a plane. Flower stems, arranged near the top of the inflorescence axis, below the stalk long, getting up short, take in a similar plane, such as Mama Hydrangea, hawthorn and so on. Such as the number of inflorescence corymbose total shaft arranged in near the top who said compound corymbs, such as Spiraea. A variant of the raceme. Order flowers from outside to inside. Such as pear, apple, cherry, etc. inflorescence. 5, flower heads (capitulum) Extreme shortening of the enlarged flower axis, flat, spreading, the bracts often integrated involucre leaves, flowers sessile, the majority of flowers _set_ was born in a receptacle to form a head shaped like a flower. Such as chrysanthemum, dandelion, sunflower and so on. 6, implicit first inflorescence (hypanthodium) Rachis swelling and retraction into the special short form, and many sessile flowers hidden cavity wall cavity was born in depression, almost all hidden, far from the top of the inflorescence leaving only a small hole and foreign the same, as the insects out of cavity spread pollen channel. Flowers and more single-sex, male distribution of the upper wall, located in the lower part of female flowers, such as fig, Ficus pumila and so on. 7, umbrella inflorescence (umbel) Floral axis shortening, most students take the top of the floral axis. Each flower has a pedicel nearly equal length, extending from the top of a peduncle nearly as long as more than a flower stalk, the flower-shaped like an umbrella, said the umbel. Each pedicel called umbrella stems. Such as Primula, Androsace, ginseng, Acanthopanax, ivy and so on. 8, spadix (spadix) The same basic structure and spikes, the difference is chunky floral axis, hypertrophy and succulent, with the majority of single-sex students sessile flowers, such as corn, cattails, the female inflorescence, and some spadix and covered with a large bract, called spathe (spathe), which is also called the Buddha of such flame flower inflorescence, such as Pinellia, Arisaema, taro and so on. Listed above are not all branches of inflorescence rachis, it is a simple inflorescence. Some other flowers of inflorescence axis with infinite branches, each branch has presented the above on an inflorescence, said this type of inflorescence compound inflorescence. There are several common look:

Compound inflorescence
1 cones inflorescence (panicle) Also known as compound raceme. Spent many long axis meristem twigs, branches and each self-contained racemes, such as Southern Tianzhu, rice, oat, yucca, etc.. 2, compound umbel (compound umbel) Rachis length of the top clusters of equal number of branches, each branch has become an umbel, a corymbose branching and self-contained, such as carrots, Peucedanum, cumin and so on. 3, compound corymbs (compound corymb) Rachis branch into the umbrella-like arrangement of rooms, each branch has self-contained corymb, flower pollination. 4, complex spike (compound spike) Rachis with 1 or 2 times branched spikes, each self-contained branch spikes, that spike, such as wheat, crabgrass and so on. 5, multiple flower heads (compound capitulum) Single flower heads on a branch, each branch of the capitulum and self-contained, such as co-head Ju.
