Shrubs. Stems erect, ascending or spreading; twigs hairy, lepidote. Leaves persistent; blade usually oblong to elliptic, rarely obovate, coriaceous, margins entire or denticulate-crenulate, plane, abaxial surface glabrous, silvery, stramineous or brownish lepidote-scaled (splitting in age); venation reticulodromous. Inflorescences terminal, (leafy) racemes, (flowers secund), 8-20-flowered, (from buds produced in previous season). Flowers: sepals 5, distinct, ovate to broadly triangular; petals 5, connate ca. 3/4 their lengths, white, corolla cylindric to urceolate-cylindric, slightly narrowed at throat, lobes much shorter than tube, (glabrous); stamens 10, included; filaments ± straight, flattened, subulate, abruptly narrowed at base, papillate, glabrous, without spurs; anther with 2 awns (awns erect, tubular, as long as body), dehiscent by terminal or subterminal pore; pistil 5-carpellate; ovary 5-locular; (style enlarged just distal to ovary); stigma slightly expanded, truncate. Fruits capsular, depressed-globose, dry-dehiscent, (with unthickened sutures). Seeds 35-50, wedge-shaped, flattened, (without wings); testa reticulate, (cells isodiametric). x = 11.
