Notulae Florae austrotiroliensis (1)

Abstract
This work marks the beginning of a new series of publications on first and new discoveries of vascular plants in the province of Bolzano. The series replaces the cycle ‘Additions and corrections to the catalogue of vascular plants of South Tyrol’ which appeared in 12 issues in this journal. The new series differs less in content than in its interlingual Latin title. Furthermore, different authors can now act as editors and the issues can be written either in German, Italian, or English, because of new academic requirements. This first edition presents 26 taxa that are new to South Tyrol, including the native and established Leontodon crispus, Orobanche elatior, and Ranunculus venetus, and non-native taxa with varying naturalization status, among them Abies cilicica, Actinidia deliciosa, Alcea setosa, Anthriscus cerefolium var. trachyspermus, Campanula poscharskyana, Centaurea montana, Chenopodium ×reynieri, Citrullus lanatus, Crocus ×luteus, Cucumis melo, Cyperus esculentus, Evansia japonica, Gamochaeta pensylvanica, Iris setosa, Metasequoia glyptostroboides, Portulaca grandiflora, Pseudotsuga menziesii, Puschkinia scilloides, Reynoutria sachalinensis, Sedum pallidum, Spiraea chamaedryfolia, and Symphyotrichum squamatum. Symphytrum tuberosum can be definitively confirmed for this area. Also new to South Tyrol is Lamium hybridum, whose indigenous status is unclear, though. Also unclear is the indigeneity of Radiola linoides, which, like the native or archeophytic Chenopodium vulvaria, Potamogeton coloratus, and P. gramineus, has been rediscovered after decades of missing records.
For several other taxa, new noteworthy distribution data are given.
