New Zealand has a new tree fern – kind of. Te Papa Research Fellow Patrick Brownsey and I have recently recognised a subspecies within the stumpy tree fern, tuokura, Dicksonia lanata.  The new name is Dicksonia lanata subspecies hispida.  It is only kind of a new tree fern, as it was first recognised as something different… Read more »

I spent yesterday afternoon in the fernery of Otari-Wilton’s Bush, examining two tree fern species from New Zealand’s subtropical Kermadec Islands. More details below, including ‘why?’. But first, a challenge… Each of these Kermadec tree ferns is closely related to a (different) mainland New Zealand species. Can you tell which mainland species? One of the… Read more »

Doodia rasp ferns become Blechnum hard ferns

  • Blechnum neglectum, previously Pteridoblechnum neglectum, found only in north-eastern Australia. Right: Blechnum diversifolium, from New Caledonia. Blechnum diversifolium is more closely related to the species previously placed in Pteridoblechnum than it is to most species of Blechnum. Photos Leon Perrie. Composite © Te Papa.
  • Blechnaceae ferns are common in several parts of the world. For instance, all New Zealanders will be familiar with kiokio and its relatives in the genus Blechnum, colloquially known as “hard ferns” because of their coriaceous fronds.  Kiokio (Blechnum novae-zelandiae) is a common sight on road cuttings, amongst other habitats, and occurs throughout the country. Photo Leon Perrie. © Te Papa.
  • Left: rasp fern, Blechnum parrisiae, previously called Doodia australis, occurs in both Australia and New Zealand. Right: Blechnum gibbum, from New Caledonia. Blechnum gibbum is more closely related to the species formerly placed in Doodia than it is to most species of Blechnum. Photos Leon Perrie. Composite © Te Papa.
  • Blechnum orientale, in Fiji. Most species of Blechnum in New Zealand are “dimorphic”, with obviously different fertile and sterile fronds. (The exception is Blechnum fraseri, which is only partially dimorphic.) However, many overseas Blechnum are “monomorphic” like Blechnum orientale, which is widespread in the tropics from Asia through Australia to the Pacific.  Photo Leon Perrie. (c) Te Papa.

A key principle in the scientific classification of animals, plants, and other living things is that the system of scientific names reflects their relationships. This is because there is only a single evolutionary history, and it provides an objective basis by which to name life. As we learn more about these evolutionary relationships, scientific names… Read more »

by Ricardo L. Palma, Curator of Terrestrial Invertebrates Evolving without wings, humans dreamed about flying for thousands of years… but only just over 100 years ago they invented a heavier-than-air machine which could fly and take them to the skies. However, long long ago, natural evolution had already provided the opportunity to fly to creatures… Read more »
