Remarks on typification of nineteen names in Tamarix (Tamaricaceae)

The earlier typifications of 12 names of Tamarix (T. arabica, T. aralensis, T. boveana, T. chinensis, T. hohenackeri, T. karelinii, T. kotschyi, T. leptopetala, T. laxa var. araratica, T. laxa var. subspicata, T. mannifera var. persica and T. pycnocarpa) are discussed. In eight cases, a second‐step lectotype was selected, because several specimens of the type collection were found at the herbaria where the first‐step lectotypes were indicated. Five previous indications of holotypes were corrected to lectotype designations, as no particular specimens had been explicitly mentioned in the protologue. The typifications of T. hampeana and T. mascatensis are clarified. Moreover, four additional names (T. bengalensis, T. gallica var. arborea, T. mannifera var. purpurascens and T. passerinoides var. macrocarpa) are lectotypified, and an epitype is selected for T. pallasii var. macrostemon. Lectotypes are designated from the material present at G‐BOIS, P, P‐LOUR, PRC, and W. Most of the 19 names treated in this work were described in the 18th and 19th centuries by important European botanists such as Bunge (12), Boissier (1), Candolle (1), Ehrenberg (3) and Loureiro (1).
