Neuropeltis is a plant genus of the family of wind plants (Convolvulaceae). The approximately 14 species are common in western Africa and Asia .
description
Neuropeltis species are woody lianas . The alternately arranged leaves are divided into petioles and leaf blades . The parchment-like or leathery one is simple and the leaf margin is entire.
The lateral inflorescences are racemose or almost panicle-shaped towards the end of the inflorescence . The bracts are initially very small, but one of the bracts increases in size as the fruit ripens, is then paper-like and clearly veined like a network. The bracts are tiny.
The hermaphroditic flowers are radial symmetry and five-fold with a double flower envelope . The five sepals are almost the same size. The crown is white or reddish in color, wheel-shaped or broadly bell-shaped and deeply lobed. The five stamens are fused with the base of the corolla tube and can protrude beyond the corolla. There are five stamens . The stamens can be finely hairy at the base . The pollen grains are not prickly. The ovary is divided into two chambers, whereby the chamber wall cannot be fully developed. Each chamber contains two ovules . The two short styles stand free from each other and have more or less lobed, shield-shaped or kidney-shaped scars .
The relatively small, hairless capsule fruits open via four flaps and contain a single seed. The seeds are spherical, smooth and hairless.
Systematics and distribution
The genus Neuropeltis was established in 1824 by Nathaniel Wallich . The type species is Neuropeltis racemosa Wall.
Within the Convolvulaceae , the genus Neuropeltis is provisionally classified in the tribe of Cresseae according to molecular biological knowledge .
Around ten Neuropeltis species are found in western Africa , the remaining species are found in Asia .
There have been around 14 species in the genus Neuropeltis since 2014:
- Neuropeltis acuminata (P.Beauv.) Benth. (Syn .: Neuropeltis vermoesenii De Wild. ): It is distributed from tropical West Africa to Angola .
- Neuropeltis aenea R.D.Good : It is widespread in western-central tropical Africa.
- Neuropeltis alnifolia Lejoly & Lisowski : It is distributed from Nigeria to western-central tropical Africa.
- Neuropeltis eladii Breteler : It wasfirst describedfrom Cameroon in 2014.
- Neuropeltis incompta R.D.Good : It is distributed from tropical West Africa to Central Africa.
- Neuropeltis indochinensis Ooststr. : It is common in Indochina .
- Neuropeltis laxiflora Lejoly & Lisowski : The home is Cameroon and Gabon .
- Neuropeltis maingayi Peter : It occurs in two varieties, both of which are common on the Malay Peninsula .
- Neuropeltis malabarica Ooststr. : It is common in southern India .
- Neuropeltis occidentalis Breteler : It was first described in 2010 and is widespread in tropical West Africa.
- Neuropeltis prevosteoides Mangenot : It occurs in Liberia and the Ivory Coast .

Nud.): It is in Myanmar , Thailand , in the Chinese provinces of Hainan and southern Yunnan andwidespreadin western Malesia in Malaysia as well as Indonesia .
- Neuropeltis velutina Hallier f. (Syn .: Neuropeltis anomala Pierre ex De Wild. , Neuropeltis sanguinea R.D.Good , Neuropeltis velutina var. Longiapiculata De Wild. ): It is spread by the western-central Africa to the south-eastern Nigeria.
