Brachyglottis repanda, the rangiora or bushman's friend, is a small, bushy tree or tall shrub endemic to New Zealand. It grows to a height of 5 to 7 meters. The petioles of the leaves have a characteristic groove up to 10 cm long. [1] The large leaves with a soft furry underside have been referred to as "bushman's toilet paper".

Other common names in Māori (beyond rangiora) include: kōuaha, pukapuka, pukariao, puke-rangiora, raurākau, raurēkau, whārangi, or whārangi-tawhito.

Description

Rangiora is a shrub / small tree which grows to around 6 m (19.7 ft.) tall and has corky bark. It has leathery 5–25 cm long, 5–20 cm wide leaves suspended off of 8–10 cm grooved petioles. The leaves are a pale green above and white underneath as the underside is covered with many tiny white hairs. [2] It flowers from August to October with dramatic panicle inflorescences made of 6 ribs and 3mm long involucral bracts. Pseudanthium are 5mm in diameter and the inflorescences contain 10–12 yellow florets. The seeds are oblong and 1–1.8 mm long, with 2–3 mm rough yellow pappus. It fruits from November to December and disperses its seeds via the wind. [3]

Etymology

Brachyglottis comes from the two greek words: Brachus, meaning short, and glottis which is the vocal apparatus of the larynx. Repanda means irregularly undulating, referring to the leaf margins. [3]

Cultivation

Rangiora is easy to grow either from seed or from cuttings, though may be short-lived and requires a hard prune after flowering. [3]

In Māori culture

Māori used the plant for a number of medicinal uses. Rangiora leaves were used for wounds and old ulcerated sores, and the gum was chewed for foul breath but was poisonous if swallowed. [4] The ethnographer Richard Taylor recorded that the leaves were used to wrap cakes made from hīnau berry meal while they cooked in a hāngī. [5] They were also used, he claimed, to line the baskets which held the siftings of raupō pollen in the process of making bread (from the pollen called pungapunga [6] ), the siftings then being thrown out. [7]

Toxins

The botanist and chemist Bernard Aston reported that the honey made by bees produced with the nectar from rangiora is poisonous, and for this reason Māori never collected honey when it was in flower. The plant is also apparently poisonous to livestock, particularly horses, making them "drunk." The animals stagger around and fall, often to their death, as a result. [8]

Parasites

B. repanda plays host to the larvae of the moth species Stigmella cypracma. [9] The larvae mine the leaves of B. repanda leaving damaged leaves in their wake. [9]

Kōwhai are small woody legume trees within the genus Sophora, in the family Fabaceae, that are native to New Zealand. There are eight species, with Sophora microphylla and S. tetraptera being the most recognised as large trees. Their natural habitat is beside streams and on the edges of forest, in lowland or mountain open areas. Kōwhai trees grow throughout the country and are a common feature in New Zealand gardens. Outside of New Zealand, kōwhai tend to be restricted to mild temperate maritime climates.

<i>Earina mucronata</i> Species of orchid

Earina mucronata is species of plant endemic to New Zealand. The specific epithet means "pointed" and refers to the shape of the tips of this orchid's very narrow leaves. The leaves are arranged alternately in one plane along a flattened, unbranched pseudobulb which can grow up to 1 m in length but which is generally shorter. As in most Monocotyledons the base of each leaf is extended into a leaf sheath which completely encircles the stem, in this species they are greatly elongated and extend the full length of the internode. The sheaths are 2 or 3 mm wide and in contrast to those of E. autumnalis they are difficult to pull off. Another key distinguishing feature of this species are the tiny, ubiquitous black spots which cover the leaf sheaths as well as many of the leaves themselves - these are notably absent in autumnalis.

<i>Entelea</i> Genus of trees

Entelea arborescens or whau is a species of malvaceous tree endemic to New Zealand. E. arborescens is the only species in the genus Entelea.

The dry fruit capsules are very distinctly brown and covered with spines. The common name whau is a Māori word that appears to derive from the common Polynesian word for hibiscus, particularly Hibiscus tiliaceus, which it superficially resembles. Alternate names include 'New Zealand mulberry', 'corkwood' and 'evergreen lime'.
