Ergänzungen und Korrekturen zum Katalog der Gefäßpflanzen Südtirols (9)

The catalogue of the vascular plants of South Tyrol: additions and corrections (9)
The ninth article in the series again presents taxa that are new to the flora of South
Tyrol or whose status has changed since the publication of the catalogue of the vascular
plants in 2006. Due to the increase in the number of members of the “Flora of
South Tyrol” working group, a comparatively large number of new records has been
obtained in the last few years. Among the new finds are the adventitious and most
likely established species Cotoneaster dielsianus, Elodea nutallii, Erigeron bonariensis,
Oenothera adriatica, Oe. deflexa, Oe. cf. latipetala, Oe. oakesiana, Oe. royfraseri, Oe.
stucchii, Verbascum sinuatum, the locally established cultural relics Cistus albidus and
C. laurifolius, as well as the casual garden refugees Allium tuberosum, Aloë maculata,
Carex muskingumensis, Chaenostoma cordatum, Eranthis hyemalis and Hyacinthoides
non-scripta. Amsinckia menziesii, Ornithopus sativus and Sesamum indicum derived from
seed mixtures or their impurities and are also unstable, while the mode of introduction
appears unclear in the case of Scrophularia scopolii. The casuals Dracocephalum
moldavica and Plantago coronopus have already been historically proven.
The status of Sisymbrium austriacum and Delosperma cooperi, also classified as adventitious,
and Juncus capitatus is unclear for the time being.
Among the new finds to be classified as native are Sorbus austriaca and Ranunculus
peltatus, the latter recently being proven to have historically occurred in South Tyrol.
After many decades, the indigenous or archeophytic species Calamagrostis canescens,
Centunculus minimus, Lathyrus aphaca, Orobanche minor, Papaver argemone, Plantago
holosteum, Ranunculus sardous, Rorippa amphibia, Rumex aquaticus, R. pulcher and
Scirpoides holoschoenus were found and reconfirmed, respectively.
New occurrences of Crepis rhaetica, Plantago atrata, Potentilla multifida, Saxifraga cuneifolia
and Trichophorum pumilum have been discovered, some of them far outside the
previously known South Tyrolean distribution area.
