dichasium [dī′kā·zhē·əm]
(botany) A cyme producing two main axes from the primary axis or shoot. Dichasium the inflorescence in plants of the cymose type. The primary axis in dichasium ends in a single apical flower. From the two opposite axils under that flower two lateral branches develop that exceed the primary axis in height and also end in flowers, which blossom later. On each of them in turn, two more lateral branches develop that overtake them in height and end in apical flowers, which blossom still later, and the process continues. Dichasium is typical for many plants of the family Caryophyllaceae and others. Sometimes branching and growth in dichasium is disturbed somewhat and inflorescences form that outwardly do not resemble dichasium (as in so-called false whorls in plants of the family Labiatae).
