The alternate leaves are arranged in a petiole and a leaf blade. The leaf stalks are relatively short. The simple leaf blades are linear to ovate or elliptical, prickly and entire.
Generative characteristics
The flowers are small and axillary either individually or in little-flowered dichasial inflorescences . The inflorescences are accompanied by two small bracts .
The hermaphrodite flowers are five-fold with a double flower envelope . The five free sepals are herbaceous and unequal. Three outer sepals are larger and often descending on the peduncle and enlarged on the fruit. The crown is colored white, broadly funnel-shaped, the coronet is five-toothed or almost entire. On the outside of the crown, five longitudinal stripes are hairy. The five stamens and the pen are not beyond the crown. The pollen grains are smooth. The ovary is bald, zweikammerig, in each ovary chamber are two ovules . A flower base is small or absent. The slender stylus ends in a double-spherical scar .
The spherical capsule fruits have two fruit compartments and open with four fruit flaps and contain four seeds .
Systematics and distribution
The genus Aniseia was created in 1834 by Jacques Denys Choisy in Mémoires de la Société de Physique et d'Histoire Naturelle de Genève , Volume 6, 2, Pages 481-484, Plate 2, f. 9 set up. A synonym for Aniseia Choisy is Aniseion St.-Lag. orth. var. Since 2017, the only species of the genus Iseia O'Donell has also belonged to the genus Aniseia .
The genus Aniseia belongs to the tribe Aniseieae within the family Convolvulaceae .
The three or so species are common in the Neotropics . Aniseia martinicensis is a neophyte in many tropical areas .
There are about three types:
- Aniseia argentina (NEBr.) O'Donell (Syn .: Ipomoea argentina N.E.Br. ): It occurs in southern Brazil , Uruguay , Paraguay and northeastern Argentina .
- Aniseia luxurians (Moric.) Athiê-Souza & Buril (Syn .: Ipomoea luxurians Moric. , Aniseia trichantha Pittier , Iseia luxurians (Moric.) O'Donell ): It is from southeastern Mexico via Central America and the island of Trinidad to tropical South America spread. It was placed in this genus in 2017.
- Aniseia martinicensis (Jacq.) Choisy (Syn .: Aniseia cernua Moric. , Convolvulus martinicensis Jacq. ): It is originally distributed in the Neotropics . It is a neophyte in many countries of the Old World.
