context_page_description: Ranunculus viridis, the Mount Allen buttercup, is a critically endangered species of alpine Ranunculus, endemic to Rakiura/Stewart Island, New Zealand, where it occurs at altitudes of 700 metres on Mount Allen in the Tin Range.
context_section_description: New Zealand has more than 40 species of wild buttercups. Thirty-four of these are native and they usually grow in mountain regions and on some predator-free offshore islands. The Mount Allen buttercup is one of three species endemic to Rakiura/Stewart Island. It is found only in the remote Tin Range on the slopes of Mount Allen. It survives in the shady damp crevices and ledges of rocky outcrops high on the mountainside at altitudes of 700m (2,300ft).  It is most closely related to R. pinguis, which is found on the Auckland and Campbell Islands, and the yellow mountain buttercup (R. sericophyllus) from the South Island.
