Introduction
Drosera arcturi Hook. from alpine southern Australia and New Zealand is very variable across its range and in Tasmania sometimes produces large, robust plants (Morris 2009), including a form bearing several conspicuous, basal glabrous leaves, a usually single, large trapping leaf, with obvious glandular hairs, and often several flowers per scape, each with 4–5 larger, greenish-white or cerise stigmas (Lowrie 1998, Clayton 2003, Gibson 2010).
