Summary
An account of the five species of Talinum native to Bolivia based on field and herbarium studies is presented. Line drawings, photographs and SEM images of seeds highlight differences in habit, inflorescence and seed morphology. A key to the species is provided and notes on diagnostic characteristics, ecology and distribution are provided. Talinum porphyreum M. Mend. & J. R. I. Wood is described as new. Additionally Phemeranthus punae (R. E. Fr.) Eggli & Nyffeler, long placed in Talinum, is recorded for the first time from Bolivia, indicating the presence of the genus Phemeranthus in Bolivia. The opportunity is taken to lectotypify this species.
