Genus: LeptosiphonView DescriptionDichotomous Key

Habit: 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.
Species In Genus: 30 species: western North America, Chile. Etymology: (Greek: narrow tube, for corollas of some species) Note: Calyx lobe membrane generally expressed as length relative to calyx or lobe length, or as width relative to calyx lobe.
