Vegetative characteristics

The Cordia styles are subshrubs , shrubs or trees . The alternate, rarely opposite leaves are divided into petiole and leaf blade. As with most members of the predatory family , the leaves of most Cordia species are clearly hairy. The leaf margin is smooth or serrate, rarely lobed. There are no stipules.

Generative characteristics

The zymous inflorescence is usually umbrella- shaped and has no bracts . The radial symmetry , mostly hermaphrodite flowers are four to eight, but mostly five. The sepals are fused tubular to bell-shaped. The petals are fused bell-shaped to tubular and are white, yellow or orange-red depending on the species. With the stamens , the stamens are often hairy at the base and there is only one stamen circle (so there are usually five stamens per flower). The two carpels are a hairless, di- or vierkammerigen, upper permanent ovary grown. Many species are heterostyle .

The spherical, ellipsoidal or egg-shaped drupes contain one to four seeds each. In some species the perianth is permanent and surrounds the fruit.

ecology

Some Cordia species serve as food plants for the larvae of some butterfly species such as Endoclita malabaricus .

The genus Cordia belongs to the subfamily Cordioideae within the Boraginaceae family . The Cordiaceae family was incorporated into the Boraginaceae family as a subfamily. Cordia used to be part of the Ehretiaceae family.

The genus Cordia has its greatest biodiversity in the New World . Some species are native to Africa and Asia . There are five species of the genus in China .

The Cordia genus includes 250 to 325 species (selection):

The following species described in the genus Cordia are assigned to other genera:

Cordia sebestena as an ornamental plant

use

Many Cordia species are popular ornamental plants in tropical to subtropical parks, gardens and avenues because of their fragrant, decorative flowers .

The fruits of some tropical species are edible. In India , fruits of native species are eaten raw, cooked or pickled as vegetables.

Wood is used by many other types:
