Abstract

A new species of Bituminaria is described and illustrated: Bituminaria antiatlantica Brullo, C. Brullo, Cambria, Cristaudo & Giusso, sp. nov., which is endemic to Anti-Atlas Mountains (Morocco). It is a true chasmophyte, characterized by a suffruticose habit, several woody branches, leaflets coriaceous, rounded to ovate, small, few-flowered inflorescences and corolla pale coloured.

Highlights

The genus Bituminaria Heist. ex Fabricius (Psoraleeae, Fabaceae), is widespread across the Mediterranean region and Macaronesian Islands, where, according to Egan and Crandall (2008), it is estimated to have diverged from other Psoraleoid genera approximately 6.78 million years ago
The causes of diversification of the Psoraleeae can be attributed mainly to range fragmentation, geographical isolation, reproductive biology, ecological adaptations, competitive factors, climatic changes and habitat modifications. These speciation processes have been active in the genus Bituminaria which is represented by eight distinct species (Stirton 1981, Greuter et al 1989, Minissale et al 2013, Giusso et al 2015, Brullo et al 2016; Bogdanović et al 2016): B. bituminosa (L.) C.H
Recent taxonomic investigations carried out on Bituminaria (Muñoz et al 2000, Minissale et al 2013, Bacchetta et al 2014, Giusso et al 2015, Toksoy et al 2015, Brullo et al 2016; Bogdanović et al 2016) highlighted that more studies were needed to discriminate clearly the taxa belonging to the B. bituminosa complex, which is widely distributed in the Mediterranean territories. As part of these investigations we examined an isolated population of plants occurring in Morocco, which had been described by Maire (1936) as Psoralea bituminosa var. rotundata
