Cyrilla racemiflora is a plant from the family of Cyrillaceae and the only species of the genus Cyrilla . The generic name honors the Italian statesman, doctor and botanist Domenico Cirillo (Cyrillus) (1739–1799).
description
Cyrilla racemiflora is an evergreen or deciduous small tree or shrub. The pedicel has two permanent bracts, the petals are thickened and covered with glands on the upper side in the middle and below the middle. The five stamens are antepetal, the stamens are awl-shaped.
The ovaries are two to vierfächrig that each subject hanging one to three ovules, the permanent pen is short and has two up four short stylus branches. The fruit is furrowed lengthways, there is one seed per compartment, the seeds are often missing.
The number of chromosomes is 2n = 40.
distribution
The species is found from northern South America to the southeastern United States, including the Caribbean.
Systematics
The species, first described by Carl von Linné in 1753 after a description by Alexander Garden , was temporarily divided into up to eleven individual species, all of which were rejected by JLThomas in 1960; the genus has since been understood as monotypical. Together with the genus Cliftonia , Cyrilla forms the family of the Cyrillaceae. Since Cliftonia is also monotypical, the family only includes two species.
