Taxon concept of I.R. Thompson (Muelleria 27(1): 36-112, 2009) includes forms that are relatively elongate, with predominantly 4-leaves per whorl and leaves with a relatively high length:width ratio with a narrower pale patch, and sometimes with a sparse stem indumentum. These forms have been recorded from lower latitudes (e.g. Ebor, Barrington Tops, Blue Mtns, Southern Highlands e.g. Wingecarribee Swamp; plants from these more northern N.S.W. localities tend to have leaves with more hairs on the margins and sometimes a minutely acuminate apex) and lower altitudes than the typical alpine or sublalpine forms from Tasmania, the eastern Highlands of Vic., the Brindabella Ranges and the Southern Tablelands of N.S.W. and the A.C.T. The different forms are not considered worthy of taxonomic recognition as they are connected through many intermediates to the typical forms (Thompson 2009).
