Sedges in the mist: A new species of Lepidosperma (Cyperaceae, Schoeneae) from the mountains of Tasmania.

George T Plunkett1, Karen L Wilson2, Jeremy J Bruhl1.   

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.

Introduction

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). Australia is the centre of diversity for , which also occurs in southern China, South-east Asia, New Caledonia and New Zealand. Species of often form important components in diverse habitats that include beach dunes, forest and woodland, sedgeland and alpine heath (Barrett 2013). The present study was initiated following the inspection by GTP of several specimens that had been identified as F.Muell. ex Rodway. Eight of the specimens, collected in south-western Tasmania, appeared morphologically and ecologically distinct from the rest of the specimens, which were collected in the east of the state and attributable to sens. strict. We intuitively segregated them as a putative new species, referred to as sp. Eldon Bluff (A.M. Buchanan 9981). Subsequent plant collections in Tasmania and a visit to the Tasmanian Herbarium (HO) further strengthened our initial impression. The aims of the study were (1) to determine the status and limits of this putative new entity and (2) to investigate its resemblance to morphologically similar named species of .

Materials and methods

Study material

A total of 25 specimens were used for the phenetic analysis (Table 1). K.L.Wilson & D.I. Morris, and F. Muell. were sampled on the basis of morphological similarity to sp. Eldon Bluff. Specimens recently collected in Tasmania and existing specimens from the N.C.W. Beadle Herbarium (NE) were used in the analysis. Specimens on loan from the National Herbarium of Victoria (MEL) and HO for a previous study (Hodgon et al. 2006) were also used, with permission.

Anatomy

Hand-cut cross-sections of culms were made in 50% ethanol using half a double edged razor blade from pickled (70% ethanol) or rehydrated herbarium material. Sections were stained in 1% safranin in 50% ethanol for c. 15 min then washed in increasing concentrations of ethanol before staining in 0.5% fast green in 95% ethanol for three to seven minutes depending on size. Sections were then transferred to increasing concentrations of histolene before mounting on glass slides with Eukitt mountant. Photosynthetic pathway was inferred from anatomy using the ‘maximum cell distance count’ criterion as applied to Cyperaceae (Bruhl et al. 1987; Bruhl and Wilson 2007).

Scanning electron microscopy

Where available, a single representative fruit in good condition was removed from each operational taxonomic unit (OTU). Additional fruit removed from non-OTU specimens PageBreakwere also used. Fruit were mounted onto an aluminium stub with double-sided carbon tabs and gold-coated using a JEOL MP-19020NCTR NeoCoater (JEOL Ltd., Tokyo). Images were captured with a JEOL JCM-5000 benchtop SEM (JEOL Ltd., Tokyo) at 10 kV. In total three fruit were imaged from , four from , seven from sp. Eldon Bluff and two from .

Characters

A character list was constructed primarily from that used by Hodgon (2001) and augmented by Barrett (2007a, b). Further characters were added based on differences among specimens observed by the authors. A total of 131 morphological and 22 anatomical characters were scored for each individual specimen (Appendix 1). Morphological characters were scored from herbarium specimens with the aid of a Leica M8 stereomicroscope. Morphological dimensions were measured once per OTU, consistently using a steel rule, electronic callipers or the microscope eyepiece graticule for each character. Fruit and perianth characters were assessed under the stereomicroscope and from SEM images. Anatomical characters were scored from permanent double-stained slides viewed under a Zeiss Axiolab compound microscope.

Analysis

Data were organised using DELTA ver. 1.04 (Dallwitz 1980) and later transferred to PATN ver. 3.12 (Blatant Fabrications) for cluster and ordination analysis (Appendix 2). Characters with multiple states scored for several OTUs were converted to multiple binary characters. Univariate characters and those used only for descriptive purposes were removed prior to analysis, as were characters that had missing values for the majority of OTUs. All characters were weighted equally in the analysis. Phenograms were produced from classification analysis run using Flexible UPGMA Agglomerative Hierarchical Fusion (β = -0.1). Three-dimensional ordination plots of semi-strong hybrid multidimensional scaling (SSH MDS) were generated. Lowest stress in the ordination analysis was achieved with 400 random starts and 100 iterations. Principal component correlation (PCC) was used to determine the importance of characters in the ordination analysis. Our species concept is consistent with that of de Queiroz (1998, 1999, 2007), which equates species with segments of separately evolving metapopulation lineages. Here we base the delimitation of species on phenetic distinguishability, ecological differentiation, and diagnosability. The presence of one of these properties provides evidence that a lineage is evolving separately and can be recognised as a species, and the presence of additional properties provides greater confidence (de Queiroz 2007). Operationally we use a morphological species concept combined with implicit use of the biological species concept (lack of gene flow and geographical separation) and an ecological species concept (most similar species occurring in distinctly different habitats). In the phenetic analyses, our criteria for accepting the putative species as a distinct entity were: (1) the OTUs representing sp. Eldon Bluff should form discrete groups distinct from all other groups of OTUs in the analyses and (2) the OTUs within these groups should show an amount of dissimilarity comparable to that of the known species included in the analyses.

Results and discussion

Phenetic analysis

The phenogram produced from the cluster analysis (Figure 1) shows distinct clusters of OTUs that match the three described and one putative species. The levels of PageBreakdissimilarity within these four groups are comparable. Groups A and B in the phenogram contain individuals of and sp. Eldon Bluff, respectively. These groups are most similar to one another, as expected, though clearly distinct. The group shows the lowest dissimilarity among individuals, possibly because of the lower number of OTUs used for that species. Group C contains individuals of and shows low dissimilarity among individuals, again possibly related to the low number of OTUs used. Group D contains individuals of and displays the highest dissimilarity among individuals, reflecting the morphological variation sampled in this species.

The ordination plot produced from SSH MDS (stress value 0.1535; Figure 2) recovered the same four groups as the phenogram. Individuals of PageBreak and respectively form the two most closely spaced groups, with individuals of forming the most distantly spaced group. Individuals of sp. Eldon Bluff form a distinct group that is close to the group containing .

Characters with a maximum correlation (r) higher than 0.7 are included. See Appendix 1 for characters and Appendix 2 for data. The images obtained with SEM demonstrated clear differences between fruits of PageBreak sp. Eldon Bluff and its closest neighbour (Figure 3). The fruit of sp. Eldon Bluff is minutely but distinctly colliculate at its distal end (Figure 3D), while the fruit of is smooth distally (Figure 3B). The size and shape of the fruit and the size of the perianth varies between the two specimens shown here (Figure 3A, C), but no consistent differences were found in perianth size and morphology between the two taxa. Based on our observation of fruit from other species of ,the wrinkled fruit of shown here, although well-developed, is slightly immature and the wrinkling is not diagnostic (old fruits on the same collection in NSW were too fragile to image but still intact enough to see that the main body is only very faintly wrinkled). More mature fruits of suitable to image were not available. Fruits of and are also smooth distally (not shown here). Observations of additional fruit under the stereomicroscope were consistent with the SEM images.

Taxonomy

The results of the phenetic analysis provide strong support for the acceptance of  sp. Eldon Bluff as a distinct entity. In both the phenogram (Figure 1) and ordination (Figure 2) a discrete group is formed by OTUs representing sp. Eldon Bluff. This group shows a level of dissimilarity that is comparable to those of the known species of included in the analysis. The SEM images also show that sp. Eldon Bluff has distinctive fruit (Figure 3). This evidence provides strong support for the recognition of sp. Eldon Bluff as a separate species from . The ecological and geographic isolation of these two entities adds further support to this inference (Figure 4; Table 3). sp. Eldon Bluff is described below as sp. nov.
