Abstract

Lepidosperma laterale exhibits much morphological variation across its geographical range. This study included L. laterale, and morphologically similar species, as well as several comparator species. Phenetic analyses based on 27 morphological and 25 vegetative anatomical characteristics were undertaken in an attempt to resolve taxonomic issues within the study group. Evidence for broadening the delimitation of L. laterale is strong as OTUs of this variable species formed a group with indistinct clusters in all analyses. The mixed, diffuse clusters obtained of OTUs of specimens identified as L. gunnii with specimens of L. laterale suggest that the species limits of the former lie within the limits of the latter. Specimens of most other study group taxa formed relatively cohesive, discrete clusters in ordination and cluster analyses. The results provide strong support for recognition of L. sp. Whian Whian S.F. (J. Hodgon 331 & D.M. Hodgon) and L. sp. Mt Coolum (P.R. Sharpe 5605A) as new species.

Appendix 1. Data matrix 1 (full data matrix) used in phenetic analyses (for data matrix see the website of Australian Systematic Botany)

Each column represents a character state. Characters and character states with all invariant and / or missing values have been removed from the matrix. –9999 = missing value. OTU codes, first three letters: GUN, Lepidosperma gunnii; AGU, L. sp. Coaldale; ELA, L. elatius; AEL, L. sp. Whian Whian S.F.; LAT, L. laterale var. laterale; LAM, L. laterale var. majus; LAA, L. laterale var. angustum; LSN, L. sp. Mt Coolum; CUR, L. curtisiae; ACU, L. sp. Hardacres; LAN, L. latens; FIL, L. filiforme; TOR, L. tortuosum; VIS, L. viscidum; GLO, L. globosum; INO, L. inops; ENS, L. ensiforme; OLD, L. oldfieldii; SER, Schoenus ericetorum; SME, S. melanostachys. Fourth letter: Q, Queensland; N, New South Wales; V, Victoria; T, Tasmania; S, South Australia; C, New Caledonia; Z, New Zealand. Herbarium location for each specimen is given in parentheses following collector information.


Appendix 2. Data matrix 2 used in phenetic analyses

The matrix is constructed by deleting all OTUs (rows) from data matrix 1, except those representing Lepidosperma laterale var. laterale, L. laterale var. angustum, L. laterale var. majus, L. gunnii, L. sp. Coaldale and L. sp. Hardacres. Characters and character states with all invariant and / or missing values are then removed.


Appendix 3. Data matrix 3 used in phenetic analyses

The matrix is constructed by deleting all OTUs (rows) from data matrix 1 representing Lepidosperma laterale var. laterale, L. laterale var. angustum, L. laterale var. majus, L. gunnii, L. sp. Coaldale and L. sp. Hardacres. Characters and character states with all invariant and / or missing values are then removed and the OTU code ENSV is changed to AELV (see text for explanation).


Appendix 4. Data matrix 4 used in phenetic analyses

The matrix is constructed by deleting all OTUs (rows) from data matrix 1, except those representing Lepidosperma elatius, L. sp. aff. elatius, L. ensiforme, L. oldfieldii, Schoenus ericetorum and S. melanostachys, from data matrix 1. Characters and character states with all invariant and or missing values are then removed and the OTU code ENSV is changed to AELV (see text for explanation).
