Acaena microphylla

Acaena microphylla, the bidibid or piripiri, [4] and outside New Zealand, New Zealand-bur, [5] is a small herbaceous, prostrate perennial flowering plant in the rose family Rosaceae, native to both the North and South Islands of New Zealand. [2] There are two varieties:

There are no synonyms. [2]

Description

Hooker describes it as "a very small and glabrous species; the leaflets not 1/4 in. long. Capitula very large for the size of the plant, upwards of an inch across, including the spines, which are not barbate, and distinguish it as a species." [3]

Taxonomy and naming

Acaena microphylla was first formally described in 1852 by Joseph Dalton Hooker. [2] [3] The genus name Acaena is derived from the ancient Greek word akaina, meaning "thorn" or "spine", [7] referring to the spiny calyx of many species of Acaena. The specific epithet microphylla derives from the Greek words, mikros (small) and phyllon (leaf), to give an adjective meaning "small-leaved". [8]

Distribution

It is found on both the North Island and South Island of New Zealand. [2]

Conservation status

In 2013, the variety Acaena microphylla var. pauciglochidiata was classified as "At Risk - Naturally Uncommon" under the New Zealand Threat Classification System. By 2018, due to an actual decline, the status changed to "At Risk - Declining". (The area of occupancy had decreased to 100 km2 or less, and the predicted decline was 10 to 50%). [1] However, the variety Acaena microphylla var. microphylla was classified as "Not Threatened" in 2004, 2009 and 2012, [4] and again in 2018. [1]

Sophora chathamica, the coastal kōwhai, sometimes known as Chatham Island kōwhai, is one of 8 species of native sophora or kōwhai in New Zealand and grows naturally in the north-west of the North Island in New Zealand, as far south as the Tongaporutu River in north Taranaki, and as far north as Te Paki. It can also be found growing near Wellington and the Chatham Islands, although these later plantings are thought to be a result of Māori plantings in the late 18th century and early 19th century. Prior to 2001, it was included as variant of Sophora microphylla, therefore references to either Sophora microphylla var. chathamica or Sophora microphylla subsp. microphylla var. chathamica are considered references to coastal kowhai.

In the heath family Ericaceae, it inhabits mountain slopes, saddles and ridges and reaches a height of 1–4 m (3–13 ft). A 2017 assessment using the New Zealand Threat Classification System classified it as “Not Threatened,” giving it an estimated population of more than 100,000.

<i>Celmisia major</i> Species of daisy

Celmisia major is a species of daisy that is endemic to New Zealand. It is split into two different varieties, Celmisia major var. major and Celmisia major var. brevis. Despite being in the same species, it is thought that the two varieties are not close to one another, with botanist Peter James de Lange stressing critical study on the taxonomy of the daisies. It was first described by Thomas Cheeseman in 1925. The major variety is found in the Auckland area and nearby islands, while the brevis variety is confined to Mount Taranaki.
