Twining woody vines (some exotic species nearly erect shrubs), with opposite entire deciduous leaves, and small yellow greenish or white flowers in terminal and axillary compound cymes. Calyx small, deeply. 5-parted, glandular within, the segments narrow. Corolla funnelform or salverform, the tube nearly cylindric, expanded above, the lobes convolute, more or less twisted. Stamens included, or short exserted; anthers sagittate, acuminate, connivent around the stigma and slightly adherent to it. Disk of 5 glandular lobes. Ovary of 2 carpels; ovules numerous in each carpel; style slender, its apex thickened below the narrow ring of the ovoid stigma. Follicles much elongated, slender. Seeds linear or oblong, not beaked, long-comose at the apex. [Greek, neck-seed, but the seed is not beaked.]
