Characteristics

Annual or perennial herbs with erect or rarely prostrate stems. Leaves alternate, cauline or forming a basal rosette, linear to spathulate, entire. Flowers in terminal racemes or corymbs; bracts at the base or near the middle of the pedicels. Calyx-tube adnate to the ovary in its lower half; limb 5-lobed, persistent. Corolla perigynous, subcampanulate; limb 5-lobed. Stamens inserted on the corolla-tube; subulate staminodes often present alternating with the stamens. Ovary subglobose; style short. Capsule globose, many-seeded, dehiscing by 5 valves. Seeds numerous, angular
More
Herbs annual or perennial. Stems erect, sometimes woody at base. Leaves alternate or sometimes basal leaves forming a rosette. Inflorescences terminal, racemose to corymbose. Calyx 5-lobed; tube fused with ovary at base or to middle. Corolla white, campanulate, 5-lobed. Stamens 5, inserted in corolla tube; filaments very short; anthers obtuse or acute at apex; staminodes 5, linear to ligulate, alternating with corolla lobes. Ovary semi-inferior; ovules numerous, semi-anatropous; style short, stigma obtuse to capitellate. Capsule globose, dehiscing by valves.
Cal campanulate, its broadly triangular lobes shorter than the tube; cor deeply 5-lobed, with a minute, scale-like staminode in each sinus; stamens about equaling the cor-tube and inserted near its base; ovary ca two thirds inferior; style very short or obsolete; stigma capitellate; capsule globose, dehiscent by 5 valves as far as the base of the cal-lobes; perennial herbs with entire lvs and small white fls in terminal (or in part axillary) racemes on slender pedicels bracteolate near the middle. 10, cosmop.
Fls in terminal or axillary bracted racemes or solitary. Stamens alt. with staminodes, on very short filaments. Ovary adnate to receptacle in lower half. Capsule 5-valved; seeds ∞, minute; embryo transverse. Annual or perennial herbs with alt. lvs. Some 100 spp., mainly of southern hemisphere.
Ovary globose; style short, stigma obtuse or capitellate; ovules numerous; placentation free–central.
