Pearl-flowered legume a surprise new find in the Cape Snowy Mountains, South Africa
Date:7/27/2011

A pearl-flowered legume collected in 2005 by Ralph Clark & Nigel Barker (Rhodes University) in the Sneeuberg, South Africa, was determined by taxonomists Charles Stirton & Muthama Muasya (University of Cape Town) to be a distinct new species. Psoralea margaretiflora is the latest endemic species from the Sneeuberg Centre of Floristic Endemism. The discovery highlights the importance of the poorly explored Great Escarpment in South Africa. The study was published in the open access journal PhytoKeys.

The Sneeuberg Centre of Floristic Endemism, Eastern Cape Province, and South Africa's newest Centre of Endemism, was recognised by Ralph Clark, Nigel Barker and Laco Mucina as recently as 2009 (Clark, V.R., Barker, N.P. & Mucina, L. 2009. The Sneeuberg: A new centre of floristic endemism on the Great Escarpment, South Africa. South African Journal of Botany 75: 196-238).

The recognition of the new Sneeuberg Centre arose out of the doctoral studies of Ralph Clark. The Great Escarpment Biodiversity Research Programme co-ordinates new research in the region and is lead by Prof. Nigel Barker at the Department of Botany, Rhodes University. The research effort is a response to the increasingly obvious lack of baseline biodiversity studies on the species-rich Great Escarpment in southern Africa. So far comprehensive biodiversity research work has been undertaken on the Sneeuberg, with further work currently being undertaken on the Nuweveldsberge, Roggeveldberge and Great Winterberg-Amatolas, and in future further afield in collaboration with other biodiversity scientists.

The Pearl-flowered Psoralea was one of several new spec
