15),the polyps produce buds right and left alternately, so that the hydranths are arranged in a zigzag fashion, forming a " scorpioid cyme," as in Obelia and Sertularia.
Terminal scorpioid cymes, small blue, pink or white flowers, a five-cleft persistent calyx, a salveror funnel-shaped corolla, having its mouth closed by five short scales and hard, smooth, shining nutlets.
The uniparous cyme presents two forms, the scorpioid or cicinal and the helicoid or bostrychoid.
The inflorescence in the family Boraginaceae are usually regarded as true scorpioid cymes.
Here there are scorpioid cymes of pairs of flowers, each pair consisting of an older and a younger flower.
In Saxifraga umbrosa (London-pride) and in the horse-chestnut we meet with a raceme of scorpioid cymes; in sea-pink, a capitulum of contracted scorpioid cymes (often called a glomerulus); in laurustinus, a compound umbel of dichasial cymes; a scorpioid cyme of capitula in Vernonia scorpioides.
