Leptinella alpina (Hook.f.) Schmidt-Leb. , comb. nov.

Ctenosperma alpinum Hook.f., London J. Bot. 6: 115–116 (1847); Cotula alpina (Hook.f.) Hook.f., Fl. Tasman. 1(3): 192, t. 51 A (1856). Type: Marlborough, Tasmania, Jan. 1841, R.Gunn 1155 (lecto, here designated: K000885266 , image seen; isolecto: BM 810481 , image seen).

We designate the duplicate at K as the lectotype because that herbarium was the workplace of Joseph Dalton Hooker, and the specimen includes labels and drawings indicating that it was used by Hooker to prepare the description. The two specimens cited above represent all the material of the original collection that is currently known. A third specimen at K is also labelled R.Gunn 1155 ( K00885265 ). However, it is dated 1844, suggesting that it is from a separate gathering. Gunn is known to have re-used numbers to refer to multiple collections that he believed to represent the same taxon, rather than using a series of unique collecting numbers ( Buchanan 1988). We therefore do not consider K00885265 to be an isolectotype.
