Thyrse:Ī branched inflorescence in which the main axis is indeterminate and the lateral branches determinate in their growth. Syconium:Ī multiple fruit with a hollow center, e.g. Spike:Īn unbranched, indeterminate inflorescence in which the flowers are without stalks. Spadix:Ī spicate inflorescence with a stout, often succulent axis. Raceme:Īn indeterminate inflorescence in which the main axis produces a series of flowers on lateral stalks, the oldest at the base and the youngest at the top. Cyme:Īn inflorescence in which each flower, in turn, is formed at the tip of a growing axis and further flowers are formed on branches arising below it.

Corymb:Ī Racemose inflorescence in which the pedicels of the lower flowers are longer than those of the flowers above, bringing all flowers to about the same level. Catkin:Ī spike in which the flowers are unisexual and without conspicuous perianth.

Heads can be determinate or indeterminate.Ī many-flowered inflorescence with an indeterminate central axis and many opposite, lateral dichasia a mixed inflorescence, with determinate and indeterminate shoots.Ī determinate inflorescence with 2 dichotomous lateral branches and pedicles of equal length.Ī determinate cyme in which the branches develop only on 1 side, due to the abortion of opposing paired bud, the inflorescence thus appearing simple.Ī tight, modified helicoid cyme in which the pedicels are very short.Ī zig-zag determinate cyme with branches developing alternately on opposite sides of the rachis, due to abortion of opposing paired bud.Ī dense cluster of sessile flowers.

Umbels can be determinate or indeterminate.Ī branched umbel, with primary rays arising from a common point, and secondary umbels arising from the tip of the primary rays.Ī dense vertically compressed inflorescence with sessile flowers on a receptacle and subtended by an involucre of phyllaries, characteristic of the Asteraceae. Inflorescence: the group or arrangement in which flowers are borne on a plant.Īn elongate, unbranched, indeterminate inflorescence with sessile flowers.Ī small spike, characteristic of grasses and sedges.Īn elongate, unbranched, indeterminate inflorescence with pedicelled flowers.Ī flat-topped raceme with elongate pedicels reaching the same level.Ī flat-topped or rounded inflorescence with the pedicels originating from a common point.
