Asplenium bulbiferum: Asplenium bulbiferum, known as mother spleenwort, is a fern species native to New Zealand only.  It is also called hen and chicken fern and, in the Māori language, pikopiko, mouku or mauku.  Its fronds are eaten as a vegetable.  It is often confused with "A. gracillimum" which is a fern species native to both New Zealand and Australia.  Earlier literature refers to the Australian plants as "Asplenium bulbiferum s.sp.  gracillimum".

The stems of the shrubs are dark when mature, covered with downy or silky hairs (tomentum) when young.  In spring, they produce clusters of small, star shaped yellow blossoms.

Tennis New Zealand: The history of tennis in New Zealand dates back to the 1870s, the decade when the development of modern tennis began.  The first "New Zealand Tennis Championships" were played at Farndon in Hawkes Bay in 1886.  New Zealand Lawn Tennis Association (NZLTA) was formed at a meeting held in Hastings in December 1886.  Shortly after its inauguration, the New Zealand Association became affiliated with the Lawn Tennis Association (England).  In 1904 New Zealand Lawn Tennis Association amalgamated with six Australian state tennis associations to form the Lawn Tennis Association of Australasia.  New Zealand Lawn Tennis Association played a significant role in the origin of the Australian Open.  Lawn Tennis Association of Australasia created the tournament called "The Australasian Mens Championships" (which later became Australian Open) in 1905 and was first played in Warehouseman's Cricket Ground and it was decided that championships would be hosted by both Australian as well as New Zealand venues.  New Zealand hosted the championship twice— Christchurch (1906) and Hastings (1912).  The geographical remoteness of both the countries (Australia and New Zealand) made it difficult for foreign players to enter the tournament.  In Christchurch in 1906, of a small field of 10 players, only two Australians attended, and the tournament was won by a New Zealander (Tony Wilding).  Lawn Tennis Association of Australasia was one of the twelve national associations of tennis which established the International Lawn Tennis Federation (ILTF) in a conference in Paris, France on 1 March 1913.  From 1905 until 1919, New Zealand and Australian tennis players participated in the International Lawn Tennis Challenge (Davis Cup) under the alias of "Team Australasia", the team claimed a title six times (1907, 1908, 1909, 1911, 1914, 1919), however, there were attempts to severance this trans-tasmanian partnership, in order to allow New Zealand players to represent their nation on international tennis events.  In 1922, New Zealand dropped out from this partnership and on 16 March 1923 New Zealand Lawn Tennis Association was granted affiliation to the International Lawn Tennis Association and thereby became eligible to enter the International Lawn Tennis Challenge in its own right.  New Zealand Lawn Tennis Association filed its first challenge with United States Lawn Tennis Association for 1924 International Lawn Tennis Challenge.  Tennis New Zealand was the founding member of Oceania Tennis Federation in 1993.
