Abstract

Jeanmonod, D. & Y. Naciri (2021). A taxonomic revision of Ranunculus sect. Batrachium in Corsica: a morphological and statistical analysis. Candollea 76: 275–292. In French, English and French abstracts.

In Corsica, the species of Ranunculus sect. Batrachium DC. are poorly defined due to a lack of sufficient observations and because the group is taxonomically complex. Our study concerns 113 individuals collected around the whole island, and is based on a biometric study of 16 morphological characters and field observations (plant development, intrapopulation variability, ecology). As a result, several species are excluded from the section and the groups Ranunculus peltatus aggr., Ranunculus penicillatus aggr., and Ranunculus trichophyllus Chaix are retained. These groups are statistically discriminated by fruiting pedicel length and multifidous leaf length. The species present on the island are Ranunculus penicillatus (Dumort.) Bab., Ranunculus saniculifolius Viv. (initially attributed to Ranunculus peltatus aggr.), and Ranunculus trichophyllus Chaix. An identification key to Corsican species is provided, as well as information concerning the ecology and distribution of each species.
