The Salvias (Lamiaceae) of Bolivia

This paper presents an account of Salvia L. in Bolivia based on the author's own field work and herbarium studies. All 28 species that occur naturally are described. The distribution, habitat, phenology and conservation status of all species is discussed. Attention is drawn to the high rate of endemism in the genus in Bolivia and to different patterns of distribution. Both dichotomous and multi-entry keys are provided to facilitate identification. Six new species are described, S. alba J. R. I. Wood, S. cardenasii J. R. I. Wood, S. ophiocephala J. R. I. Wood, S. raymondii J. R. I. Wood, S. serranoae J. R. I. Wood and S. sucrensis J. R. I. Wood. One naturally occurring hybrid is named S. × westerae J. R. I. Wood. Subspecies are recognised for geographically separated populations of three variable species. Subsp. mairanae J. R. I. Wood of S. raymondii is described as new; S. platystoma Epling is treated as a subsp. platystoma (Epling) J. R. I. Wood of S. rypara Briq.; S. cuspidata Ruiz & Pavon is treated as a widespread species that has three recognised subspecies, subsp. bangii (Rusby) J. R. I. Wood from Bolivia, subsp. gilliesii (Benth.) J. R. I. Wood centred on Argentina and subsp. rosea J. R. I. Wood described as new. High Andean plants previously treated as S. rhombifolia Ruiz & Pavon are shown to be a distinct species whose correct name is S. tafallae Benth. Several Argentinian species, including S. rhinosina Griseb., S. exserta Griseb. and S. australis Epling, are reassessed. All new taxa are illustrated and distribution maps are provided.
