description

Ipomoea imperati is an upright herbaceous plant or a creeping or sometimes ascending liana that is somewhat woody and reaches up to 2 m in length. It forms a milky sap . The stems are cylindrical, thin and hairless, adventitious roots are formed in the area of ​​the nodes . The leaves are alternate and usually in groups on short side shoots. The leaf blade is simple, 2 to 10 cm long and 1 to 2.5 cm wide, and glabrous. It can be lanceolate, oblong, triangular or sometimes arrow-shaped, rarely three-lobed. They are fleshy when fresh, but paper-like when dried. At the top they are blunt or rounded, sometimes also edged and spiky. The base is wedge-shaped, truncated, almost heart-shaped or almost arrow-shaped. The top is dull and hairless, the veins do not emerge. The underside is also hairless, but here the midrib and the side veins extending from it emerge. The leaf stalks are 1 to 6.5 cm long, furrowed and finely hairy at the tip.

The flowers are solitary or in ascending dichasias . The flower stalks are 1.5 to 4.5 cm long. The calyx is green and does not enlarge on the fruit. The sepals are hairless, elliptical, awned at the tip and translucent at the edge. They are 10 to 15 cm long, the two outer ones are slightly larger than the inner ones. The crown is white and yellow in the middle and funnel-shaped. It is 2.5 to 5 cm long, the coronet measures 3 to 6 cm in diameter and is covered with five weak, blunt lobes. The stamens and stigma do not protrude beyond the crown.

The fruit is a spherical or cone-shaped capsule with a length of 1.2 to 1.5 cm. One to four seeds are formed per fruit . These are about 5 mm long and woolly hairy.

Systematics

The species is named after the Neapolitan naturalist Ferrante Imperato (1550-1631), who first described and illustrated it in 1599 in his work Historia Naturale . The basionyma Convolvulus imperati was first published by Martin Vahl in 1790 , the combination Ipomoea imperati in 1866 by August Heinrich Rudolf Grisebach . Important synonyms are Convolvulus sinuatus Petagna (non Ipomoea sinuata Ortega ), Convolvulus stolonifer Cirillo nom. illegal. and Ipomoea stolonifera (Cirillo) JFGmel. nom. illegal.

Ipomoea imperati belongs within the genus Ipomoea to the section Erpipomoea Choisy within the subgenus Eriospermum (Hallier f.) Verdc. ex Austin .

Occurrence

The species is widespread in coastal areas with a tropical to warm climate and occurs in Africa, tropical and subtropical Asia, Australia, North and Central America and the Pacific islands. In the north, the Japanese ( Ogasawara and Ryūkyū Islands ) are reached in East Asia , and in Europe the Azores ( Terceira , Pico , Faial ) and the Mediterranean region. In Spain, the occurrence on Cabrera (Balearic Islands) is based on error, the recent records from the Spanish mainland are not considered indigenous. It is also widespread in Italy (Sicily and lost at Locus classicus in Campania), in Greece (Crete and Rhodes), on the south coast of Anatolia, on Cyprus, in Lebanon, in Israel and in Morocco, Algeria, Libya and in Egypt. It occurs on sandy coasts.
