Parasitic, twining herb. Stems slender to medium, yellowish. Inflorescences loose clusters; pedicels short. Flowers 3-4 mm long, glandular. Calyx shorter than corolla tube, lobed halfway down; lobes ovate-triangular, acute, edges revolute, sinuses rounded. Corolla long-campanulate to funnel-shaped, yellow; lobes ovate-triangular, apex acute, inflexed. Stamens shorter than corolla tube; filaments as long as anthers. Scales not reaching stamens, oblong to triangular-ovate, apex free, shortly fringed. Ovary globose; styles slender, often unequal, as long as ovary. Flowering time Jan., Feb. Fruit a globose capsule, irregularly dehiscent. Seeds 1.5-2.0 mm long, subglobose.
Stems slender to medium.. Flowers ± glandular, 3–4 mm. long, in loose racemose clusters; pedicels equalling or longer than the flowers.. Calyx-lobes shorter than the corolla-tube, triangular-ovate, abruptly acute, with edges often revolute (but not so in Nattrass 209).. Corolla 3–4 mm. long; lobes triangular, acute, shorter than the tube, somewhat thickened and inflexed at the apices.. Stamens a little shorter than the lobes.. Scales oblong, irregularly fringed, almost or quite reaching to the base of the corolla-lobes.. Styles long and slender, up to 2 mm. long, equalling the globose ovary.. Capsule globose, not splitting around the base.
Twining parasite. Inflorescence a very loose cluster. Calyx lobes obtuse or abruptly acute. Scales in corolla tube free, not bifid at apex, not reaching base of free part of filaments. Styles 2, free to base; stigmas globose. Flowers white.
A S. Amer. sp., has been reported from our range on alfalfa. It differs from no. 5 [Cuscuta indecora Choisy] most notably in that the ovoid-globose fr is not thickened around the styles.
Corolla campanulate or funnel-shaped, becoming globular about the developing capsule; lobes ovate-triangular with acute inflexed and somewhat thickened apices shorter than the tube.
Calyx shorter than the corolla tube; lobes ovate-triangular, more or less acute, not overlapping, often with revolute edges, separated by usually rounded sinuses.
Ovary globose; styles long and slender, about equal to the ovary or sometimes longer and distinctly unequal.
Scales usually not reaching the stamens, oblong, ovate or triangular-ovate irregularly fringed.
Stamens shorter than corolla lobes; filaments about as long as the anthers.
Flowers 3–4 mm. long, more or less glandular; pedicels variable in length.
Capsule globose, not splitting around the base.
Inflorescences loose racemose clusters.
Seeds subglobose, 1·5–2 mm. long.
Stems slender to medium thick.
