Contributions to a catalogue of alien plants in Tasmania III

Abstract

The status of six alien plant taxa recorded in 111smania is discussed. Cordyline australis (G.Forst.) Endl., Lupinus X regalis Bergmans, Pitto sporum crassifolium Banks & Sol. ex A. Cunn., Pittosporum eugenioides A. Cunn., Pittosporum tenuijolium Gaertn. and Pittosporum undulatum Vent. are ornamental taxa that are now recognised as naturalised in Tasmania. A description for each taxon is provided and distribution and habitat details are discussed. Keys to the Tasmanian species of Lupinus L. and Pittosporum Banks ex Gaertn. are included.

Pittosporum undulatum Vent. is an invasive tree on Robinson Crusoe Island (Juan Fernández Archipelago), Chile

“…To my knowledge, P. eugenioides has never been found as clearly invasive (Rejmánek & Richardson 2013). It is occasionally naturalized in Tasmania and continental Australia (Baker 2011, Hosking et al 2007). However, Pittosporum undulatum is a very difficult invader on many islands and even in parts of Australia where it is not native (Bellingham et al 2018, Gleadow 1982, Lourenço et al 2011, Silva et al 2017, Smith-Ramírez et al 2017.…”

Contributions to a catalogue of alien plants in Tasmania IV

“…This paper is the fourth of a series (Baker 2005(Baker , 2007(Baker , 2011) which aims to ensure that taxa that become naturalised in Tasmania are formally recorded; that taxa that are present in Tasmania, but have not become fully naturalised ("sparingly naturalised" in the sense of Buchanan (2005) and Baker (2005)) are likewise recorded; that new incursions of alien taxa are recorded; and to maintain up-to-date names for taxa that have been affected by nomenclatural change. In this paper, four species that were introduced as garden ornamentals (Mirabilis jalapa L., Phytolacca octandra L., Coleonema pulchellum I.Williams and Gomphocarpus fruticosus (L.) W.T.Aiton) are treated, giving diagnostic descriptions and notes on their distribution.…”
