Abstract
The status of a putative new species of Lepidosperma from the mountains of south-western Tasmania, Australia, was investigated. Phenetic analysis (Flexible UPGMA Agglomerative Hierarchical Fusion and semi-strong hybrid multidimensional scaling) was conducted on a database derived from morphological and anatomical characters scored from herbarium material, culm anatomy slides and scanning electron micrographs of fruit. The results of the analysis support the recognition of a new species, here described as Lepidosperma monticola G.T.Plunkett & J.J.Bruhl. The distribution, habitat and conservation status are discussed.
Highlights
Lepidosperma Labill. (Cyperaceae) is a genus of c. 75 described species (Barrett and Wilson 2012) and up to 230 species based on current estimates of undescribed taxa (Barrett 2012)
A total of 25 specimens were used for the phenetic analysis (Table 1)
The phenogram produced from the cluster analysis (Figure 1) shows distinct clusters of operational taxonomic unit (OTU) that match the three described and one putative species
Summary

(Cyperaceae) is a genus of c. 75 described species (Barrett and Wilson 2012) and up to 230 species based on current estimates of undescribed taxa (Barrett 2012). 75 described species (Barrett and Wilson 2012) and up to 230 species based on current estimates of undescribed taxa (Barrett 2012). Australia is the centre of diversity for Lepidosperma, which occurs in southern China, South-east Asia, New Caledonia and New Zealand. Plunkett et al / PhytoKeys 28: 19–59 (2013)
