is a monotypic genus which contains only one species, Emmenanthe penduliflora
, known by the common name whispering bells
. This is a grassland wildflower found in the western United States. It is an annual plant with fleshy foliage which exudes a sticky juice with a light medicinal odor. The plant comes up from a weedy-looking basal rosette of sharply lobed leaves. It produces long inflorescences hung with small yellow or pink bell-shaped flowers which dry and become light and papery. The dry hanging flowers make a rustling sound when a breeze comes through, giving the whispering bells its common name. The dry flower also contains a fruit about a centimeter wide. This flower is most common in dry, recently burned areas; germination of the seeds may be triggered by the presence of burned plant material. It is a common plant of the chaparral
ecosystem, which is prone to wildfire.
