Prumnopitys ferruginea, commonly called miro, is an evergreen coniferous tree which is endemic to New Zealand. Before the genus Prumnopitys was distinguished, it was treated in the related genus Podocarpus as Podocarpus ferrugineus.

It grows up to 25 m high, with a trunk up to 1.3 m diameter. The leaves are linear to sickle-shaped, 15–25 mm long and 2–3 mm broad, with downcurved margins. The plants are dioecious with pollen cones being solitary while those of female plants hang from a curved, scaly stalk. The seed cones are highly modified, reduced to a central stem 2–3 cm long bearing 1-3 scales, each scale maturing berry-like, oval, about 20 mm long and 10–15 mm broad, red to purple-red with a soft edible pulp covering the single seed. The seeds are dispersed by the New Zealand pigeon, which eats the very conspicuous 'berries' and passes the seeds in its droppings. It is found growing on both lowland terrain and on hill slopes throughout the two main islands as well as on Stewart Island/Rakiura (47° S). [2] The Tree can live for at least 600 years. [2]

The scientific name ferruginea derives from the rusty colour of dried herbarium specimens of the leaves. The Māori name miro comes from the Proto-Polynesian word milo which refers to the Pacific rosewood (Thespesia populnea) in tropical islands far north. [3]

Distinguishing miro from mataī

Miro is distinguished from the related, and (initially) very similar looking mataī (Prumnopitys taxifolia) in four aspects of its anatomy; its cones, bark, seeds and leaves.

Phyllocladus, the celery pines, is a small genus of conifers, now usually placed in the family Podocarpaceae.Species occur mainly in New Zealand, Tasmania, and Malesia in the Southern Hemisphere, though P. hypophyllus ranges into the Philippines, a short way north of the equator.

<i>Platycladus</i> Genus of conifers

Platycladus is a monotypic genus of evergreen coniferous trees in the cypress family Cupressaceae, containing only one species, Platycladus orientalis, also known as Chinese thuja, Oriental arborvitae, Chinese arborvitae, biota or Oriental thuja. It is native to northeastern parts of East Asia and North Asia, but is also now naturalised as an introduced species in other regions of the Asian continent.

<i>Podocarpus</i> Genus of conifers in the family Podocarpaceae

Podocarpus is a genus of conifers, the most numerous and widely distributed of the podocarp family, the Podocarpaceae. The name comes from Greek πούς + καρπός. Podocarpus species are evergreen shrubs or trees, usually from 1 to 25 m tall, known to reach 40 m (130 ft) at times. The cones have two to five fused cone scales, which form a fleshy, berry-like, brightly coloured receptacle at maturity. The fleshy cones attract birds, which then eat the cones and disperse the seeds in their droppings. About 97 to 107 species are placed in the genus depending on the circumscription of the species.

<i>Nageia</i> Genus of conifers in the family Podocarpaceae

Nageia is a genus of conifers belonging to the podocarp family Podocarpaceae. Nageia includes evergreen shrubs and trees, from one to 54 meters in height. A 2009 treatment of the genus recognized five species. Some authors consider Nageia formosensis to be a separate species from Nageia nagi, thus recognizing six species. The podocarp genera have been reshuffled by various botanists. Most recently, several species formerly classed as Nageia were moved to the new genus Retrophyllum, while Nageia falcata and Nageia mannii were moved to the new genus Afrocarpus.

<i>Euclea crispa</i> Species of tree

Euclea crispa, commonly known as the blue guarri, is an Afrotropical plant species of the family Ebenaceae. The hardy and evergreen plants may form a dense stand of shrubs, or grow to tree size. It is widespread and common in the interior regions of southern Africa, and occurs northward to the tropics. Though some are present near the South African south and east coasts, they generally occur at middle to high altitudes. It is readily recognizable from its much-branched structure and dull bluish foliage colour. Those bearing lanceolate leaves may however resemble the Wild olive, another common species of the interior plateaus.
