Pirita - Green Mistletoe


Botanical name:  Ileostylus micranthus
Maori name:  Pirita
Common name:  Green mistletoe

Pirita, a member of the mistletoe family, is described as a woody, epiphytic, much branched hemiparasite. Its leathery green leaves use photosynthesis to produce the sugar and starch necessary for plant cell formation. It also uses its attachment to the host plant to tap into sap channels to get water and mineral salts. It can form several of these attachments which are called haustoria. From September to December, pirita produces tiny greenish yellow flowers which are pollinated by insects. Following pollination small berries ripen to a bright yellow from December to April. The berries are sweet and juicy and were eaten by Maori.

Pirita is spread mainly by birds, who eat the berries and then wipe their bills on tree-bark to remove the sticky seeds. The seeds get lodged in cracks in the bark and germinate there.

Only two pirita plants have so far been found on Tiritiri. They are attached to Karo (Pittosporum crassifolium). It is hoped that sharped-eyed botanists visiting the Island will discover more.
