description

Vegetative characteristics

Aniseia luxurians is a strongly branched liana , the shoots of which are hairy with backward-pointing, fine to fine-felted, reddish, sloping trichomes . Roots form at the nodes .

The leaves are elliptical with a length from 1.5 to 12 centimeters and a width of 0.5 to 4 centimeters, oblong to lanceolate with wedge-shaped to rounded and blunt Spreitenbasis to sharpened and stachelspitzigem upper end. Most of the leaves are hairy, at least along the main veins, with attached, later sloping trichomes.

Inflorescence and flower

The flowers stand individually or in pairs to ten in mostly hairy zymose and inflorescences . The flower stalks are 3 to 10 mm long.

The hermaphrodite flowers are five-fold with a double flower envelope. The sepals are 7 to 12 mm long and 5 to .7 mm wide, elliptical to obovate with a blunt to pointed and spiky upper end, mostly hairy and ciliate. The inner sepals often have only a line-shaped hair lying in the middle. The crown is white, funnel-shaped and 3 to 4 inches long. The thickenings along the axis of the petals (interplicae) are densely tomentose.

The stamens are unevenly shaped, the stamens are hairy glandular at the base. The ovary is ovoid, hairless at the base but hairy towards the tip. The stylus has a double-spherical scar .

Fruit and seeds

The black capsule fruit does not open, is almost spherical and hairless with a diameter of 9 to 14 mm or finely hairy on the upper side. They contain four dark, 4 to 6 mm long seeds that are hairless or covered with trichomes on the edge.

Occurrence

The distribution area of Aniseia luxurians extends from Honduras to the northern part of Argentina . It can be found there mainly on river banks.

Systematics

Within the Convolvulaceae, the genus Aniseia is classified into the Aniseieae tribe according to molecular biological knowledge . In addition to the genus Aniseia , the genera Odonellia and Tetralocularia also belong to this tribe. Previously, Iseia was also assigned to the tribe Merremieae or the tribe Cresseae .
