The orange flowers ( Choisya ) are a small plant genus in the family of the Rutaceae (Rutaceae) from the southern North America . The genus got its botanical name after the Swiss botanist Jacques Denis Choisy .
description
Orange flower species are evergreen shrubs that reach heights of between 1 m and 3 m depending on the species.
The opposite leaves are fingered, with some species threefold, with others up to thirteen. The shape of the leaflets can be linear to broadly ovoid. The leaves contain numerous inclusions of essential oil and give off a strongly aromatic, orange-like odor when rubbed.
The white flowers also smell strongly of oranges. There are too few of them in the leaf axils or at the end in small umbels. The number of petals is between four and seven, but usually five petals are present. Stamens are 8 to 15 present, the stamens widened like a leaf and like the petals are pure white. They form two- to sixfold, leathery capsule fruits .
distribution
All species come from southern North America or northern Central America ( Texas , Southwest USA and Mexico ).
use
Some species of the genus are cultivated as ornamental plants, most of which can only tolerate light frost. Choisya 'Aztec Pearl', a hybrid of Choisya arizonica and Choisya ternata , is one of the most popular ornamental plants of the genus because of its three to five-fold, narrow leaves.
species
Depending on the author, the genus consists of five to eight species, as Choisya mollis and Choisya arizonica are also considered to be varieties of Choisya dumosa and Choisya grandiflora can be used as a synonym for Choisya ternata .
- Choisya arizonica Standl. : It only occurs in Arizona .
- Choisya dumosa (Torr.) A. Gray , with up to 13-part leaves made up of very narrow leaflets. It occurs in Arizona, New Mexico, Texas and the Mexican state of Chihuahua.
- Choisya grandiflora rule is also Choisya ternata found
- Choisya katherinae C.H. Garbage. : It occurs in the Mexican states of Chihuahua and Coahuila.
- Choisya mollis standl. : It was described from Mexico.
- Choisya neglecta C.H. Garbage. : It was described from Mexico.
- Choisya palmeri Standl. : It was described from Mexico.
