Foliage leaves alternate, sometimes with much reduced internodes, linear to elliptical, apically obtuse to long caudate-acuminate, subsessile or sessile to amplexicaul, rarely perfoliate, often parallel-veined, sometimes reticulate-veined, sometimes dark-spotted. Inflorescence terminal or axillary, often 1-flowered, or umbelliform, sometimes a thyrse or a thyrsoid, rarely a raceme. Flowers bisexual, hypogynous, actinomorphic, erect or nodding, often showy.

Stamens usually 3 + 3, rarely 3 + 0 (Scoliopus), free, inserted at tepal base. Filaments often subulate or flattened, dilated at base, sometimes filiform. Anthers often oblong, sometimes sagittate, lanceolate or linear, dorsifixed versatile or basifixed, extrorse or latrorse.
