Updated typification of the Tasmanian pteridophytes described by Labillardière in his Novae Hollandiae plantarum specimen of 1806

Abstract

We present updated type information on the Tasmanian species of ferns and lycophytes described by Labillardière in his Novae Hollandiae plantarum specimen of 1806. Among the 13 names introduced, we list a total of 80 specimens with type status (13 lectotypes and 67 isolectotypes), mainly from FI, which houses Labillardière's herbarium (and the main set of plants) in FI‐W, but also from B (including B‐W), BM, F, G, GH, K, L, LE, MEL, P (including P‐JU), PRC, RB, and WAG. Another nine specimens are cited as probable isolectotypes, since they lack confident label data. Four lectotypifications and one second‐step lectotypification are newly proposed. Some specimens previously regarded as “holotypes” are better referred to as inadvertently chosen lectotypes. We show evidence that Lindsaea lanceolata Labill. (= L. ensifolia Sw. subsp. ensifolia), although originally described from Tasmania, was probably mislabeled, and the specimen was actually from Amboyna (= Ambon), Indonesia. We provide an Appendix with links to online images of nearly all type specimens.
