Leptinella rotundata, or Northland button daisy is endemic to the North Island. This nationally endangered species grows on exposed areas on coastal cliffs and boulder falls amongst low vegetation in areas from the Waitakere Range north to Scott's Point, Te Paki which is just south of Cape Maria Van Diemen. It occupies a very specific habitat, preferring the wind and salt blasted margins of vegetated cliff faces, where other competing plants are held in check. It is typically sparse and patchy in its distribution at any given site. It is a small creeping, hairy herbaceous plant, sparingly branched, that forms diffuse patches. It has thick, yellowish, sparsely hairy, rounded leaves that are about 15 mm long, with toothed margins on a long stalk. Flowering generally occurs on separate male and female plants from August to January, but sporadic flowering can occur at any time of the year. The flower stems are up to 60 mm long and have a single yellow-green, button-like flowerhead. The species was rediscovered in April 2010, in the Waitakere Ranges some 113 years after it was first found there by Thomas Cheeseman, and 104 year after it was described by him as new to science from those gatherings. It is threatened at all known locations by coastal erosion, weed invasion of its narrow cliff-top and boulder bank habitats, and by the seemingly natural separation of male and female plants. Thus in the wild, as far as is known, seed is rarely if ever formed.
