Annual, perennial herb.
Stem: generally erect, generally branched from base.
Leaf: cauline, opposite, entire or lobes 3–9, palmate, linear to narrowly lanceolate or spoon-shaped, generally not fused by membrane.
Inflorescence: head, open clusters, few-flowered cyme, or flower 1; bracts ± leaf-like, generally palmate-lobed, lobes generally not connected by translucent membrane; flowers sessile or not.
Flower: sepals generally equal; corolla funnel-shaped, salverform, or bell-shaped, with hairy ring inside tube or generally not (determined at 10×); stamens attached at 1 level, pollen yellow.
30 species: w North America, Chile. (Greek: narrow tube, for corollas of some species) [Battaglia & Patterson 2001 Madroño 48:62–78] Calyx lobe membrane generally expressed as length relative to calyx or lobe length, or as width relative to calyx lobe.
