Abstract
The Linnaean name Arenaria tenuifolia (Caryophyllaceae) is lectotypified on a specimen preserved at LINN (no. 585.36). To verify its identity, the names A. dichotoma (nom. illeg.), A. hybrida (currently Sabulina tenuifolia), A. tenuifolia var. vaillantiana (currently S. tenuifolia subsp. vaillantiana), Minuartia hybrida var. palaestina, M. hybrida var. parviflora, and M. hybrida subsp. turcica (currently S. tenuifolia subsp. turcica) were investigated. Two iconography, one by Villars and a second by Vaillant are designated as lectotypes of A. hybrida, and A. tenuifolia var. vaillantiana respectively. In addition, the holotypes of M. hybrida var. palaestina, M. hybrida var. parviflora, and M. hybrida subsp. turcica (basyonim of S. tenuifolia subsp. turcica) were examined at WU (var. parviflora) and E (var. palaestina, and subsp. turcica). The results show that Linnaeus’s 1753 A. tenuifolia, has priority over Villars’ 1779 A. hybrida. Therefore we here confirm the treatment of these two names by M. Dillenberger and J. Kadereit although neither name was typified by them. All of the above names are included in Sabulina. Since var. palaestina and var. parviflora have not yet transferred to Sabulina two new combinations are proposed herein, namely S. tenuifolia var. palaestina, and S. tenuifolia var. parviflora.
