Aciphylla colensoi

Aciphylla colensoi is a species of Aciphylla, commonly known as giant speargrass, Spaniard, or by its Māori-language name taramea.[3] Individual plants may be up to 90 cm (35 in) in diameter and up to 1 metre (39 in) high when in flower, and consist of sharp spines, all pointing out from the centre. The leaflets are thick, and have rough margins and red-orange midribs. Yellow flowers may also be present, located on long, narrow, and strong stems.[4][5] A. colensoi is endemic and can be found in both main islands of New Zealand, typically in altitudes from 900 to 1,500 m (3,000 to 4,900 ft).[4]

Joseph Hooker first described the plant in 1864.[1][2] The specific epithet, colensoi, honours William Colenso.[2][5]

Distribution

It is found on both the North and South Islands of New Zealand from south of Mount Hikurangi through to the middle of Canterbury.[4][6] It is found from 900 to 1,500 metres (3,000 to 4,900 ft) in subalpine to low alpine areas. They are often found in moist conditions on sites featuring a mix of snow tussock scrub, grassland, and herbfields.[5]

Conservation

The decline of A. colensoi due to browsing from rabbits was noted as early as 1883.[7] Its conservation status as of 2023 is Not Threatened.[4]
