Plant Material Exchanged between James Petiver (ca. 1663–1718) and Joan Salvador I Riera (1683–1725). I. The Balearic Plants Conserved in the Bc-Salvador and Bm-Sloane Herbaria

The BC-Salvador herbarium, conserved in the Botanic Institute of Barcelona, is the oldest plant collection known in Spain, with 4025 sheets collected between the late seventeenth century and the middle of the eighteenth. Joan Salvador, the main contributor, sent duplicates of some of these sheets to James Petiver and Hans Sloane; the sheets are now conserved as a part of the BM-Sloane herbarium. Both herbaria conserve the testimonies of the first well-known systematic explorations of the Balearic Islands carried out by Joan and Josep Salvador between 1711 and 1725. In this article we list the contents of Petiveriana III, published by Petiver in 1717, in which some Balearic plants are described as new taxa by Joan Salvador, and we point out the sheets of the BC-Salvador and BM-Sloane herbaria on which these diagnoses are based.
