Description:

  • Shrubs or small trees
  • Leaves petiolate, oblong, elliptic or lanceolate-elliptic, usually paler on undersurface; stipules shortly connate at base, shortly subulate, villous within, soon falling
  • Flowers in few- to many-flowered, dichotomously branched, axillary cymes, or terminating short, lateral shoots; peduncles short; pedicels mostly elongate
  • Calyx deeply 5-lobed; lobes usually almost as long as or longer than tube, elongate-spathulate or narrowly oblong-spathulate, obtuse; tube short, subglobose
  • Corolla 5-lobed, yellow, glabrous or hairy; lobes elongate, acuminate or acute, reflexed; tube cylindric to campanulate, with ring of deflexed hairs near base within, glabrous or sparsely hairy at throat
  • Stamens 5, arising in corolla mouth, exserted; filaments shorter than anthers; anthers apiculate
  • Disc annular, tumid
  • Ovary 5-locular, with a single pendulous ovule in each locule; style filiform, usually exserted; stigma broadly cylindric, sulcate, shortly 5-lobed
  • Fruit a drupe varying in shape according to number (1-5) of pyrenes developed; pyrenes asymmetrically ellipsoid, pyriform or subglobose with woody walls
  • x = 11 (high polyploidy)
