Stem: often forked.
Leaf: opposite, sessile or petioled, pairs generally unequal; blade generally entire.
Inflorescence: generally forked; spike, head-like cluster, or umbel, flowers rarely 1, bracts forming a calyx-like involucre or not.
Flower: bisexual, generally ± radial ( bilateral), sometimes cleistogamous in some genera; perianth of 1 whorl, generally petal-like, bell- to trumpet-shaped, base hardened, tightly surrounding ovary in fruit, lobes 3–5, generally notched to ± lobed; stamens 1–many; ovary superior (appearing inferior due to hardened perianth base), style 1.
