Sticherus cunninghamii

Sticherus cunninghamii, also known as umbrella fern, is a New Zealand endemic fern. The species is named after English botanist and explorer Allan Cunningham; its Māori names include rarauheriki, waekura and tapuwae-kōtuku. Umbrella fern is characterised by its drooping fronds that resemble an umbrella, distinct from the fan-like fronds of its relative S. flabellatus. The angle between the first branches on the frond is narrow, about 44°. Fronds are 15–30 cm long with an erect stipe between 20 and 50 cm high, but reaching 1 m at times.The last, longest leaf segment on the frond is up to 18 mm, and unlike in S. flabellatus is not serrated. Leaves are divided into two halves which fan out, with a dormant bud between them which sometimes grows into additional pinnae, especially in plants growing along the ground rather than up banks. The underside of the leaf segments is white or glaucous, and is covered with broad scales which are brown in the centre and fade to pale on the margins. Sor......read more on Wikipedia.
