The flat, star-shaped flowers are 1-cm across, range in color from maroon in the sun to pale beige in the shade, and are displayed in loose cymes in the leaf axils.
This pattern is most clearly observed in shoots with five to seven cymes, while in shoots with two to four cymes male flowers are also frequently produced in basal positions.
Inflorescences are terminal or axillary, and are usually cymose , but less often racemose, capitate, clustered or spicate; the flowers are seldom solitary.
Their inflorescences are racemose or cymose , and aggregated in dichasial units.
Leaves of C. orbiculatus are broader, and the flowers are borne in axillary cymes .
The flowers are violet blue or bright blue, funnel or bell shaped and are five to 12 in number, produced on loose cymose clusters having small, five angled corolla 1.5 cm across.
The buckwheat inflorescence is a compound raceme that produces laterally flowered cymose clusters, the number of which was affected by the position of the inflorescence along the main stem.
S. wallichii and S. wightianus, native to India, produce numerous small flowers in terminal cymose or corymbose inflorescences.
The terminal and erect cymose inflorescence bears actinomorphic, hexamerous, dish-shaped flowers.
