Monograph of Coccinia (Cucurbitaceae)

Area of Science:

• Botany
• Plant Taxonomy
• African Flora

Background:

• The genus Coccinia (Cucurbitaceae) encompasses numerous described names, necessitating a taxonomic revision.
• Understanding the diversity and distribution of Coccinia is crucial for conservation and ethnobotanical studies.

Purpose of the Study:

• To conduct a comprehensive taxonomic monograph of the genus Coccinia.
• To identify and describe new taxa within the genus.
• To map the distribution and characterize the habitats of Coccinia species.

Main Methods:

• Examination of 3157 collections, with 2024 georeferenced for distribution mapping.
• Morphological analysis of floral and fruit characteristics.
• Review of existing taxonomic literature and type specimens.

Main Results:

• Recognition of 25 species within the genus Coccinia.
• Description of three taxonomic novelties: Coccinia adoensis var. aurantiaca, Coccinia sessilifolia var. variifolia, and Coccinia adoensis var. jeffreyana.
• All species are found in sub-Saharan Africa, with Coccinia grandis having a wider distribution.

Conclusions:

• The monograph provides a modern taxonomic framework for the genus Coccinia.
• Coccinia species exhibit diverse ecological adaptations and are utilized for food and medicinal purposes.
• Further research into the ethnobotany and conservation of Coccinia is warranted.
