아키필라 아우레아-[정명] Aciphylla aurea W.R.B.Oliv.

Aciphylla aurea, known as taramea in Māori and golden speargrass or golden Spaniard in New Zealand English, is a large, spiky, tufted plant with sharp yellowish-green leaves in the speargrass genus Aciphylla. A. aurea is found throughout the South Island of New Zealand in montane to low alpine habitats.

Taxonomy and etymology

This species was first described in 1956 by the New Zealand botanist Walter Oliver. The type locality of this species is Swampy Hill in Otago and the several syntype specimens, collected by Oliver on 25 November 1950, are held at Te Papa. The species epithet aurea refers to the distinctive golden colour of the plant.

Description

Plants are yellow-green, tufted herbs up to 1.5 m high (when in flower or fruit) with spiky rosettes up to 1 m diameter, and dioecious (with separate male and female plants). Leaves are up to 70 cm long, once- or twice-pinnately compound, petiolate, with thick, wide sheaths and stiff, sharp, tapering stipules up to 27 cm long. Petioles are up to 20 cm long and 16 mm wide and serrulate. Pinnae in 1–2 pairs, about 20 cm long, erect, serrulate. Stems are thick, ribbed, bracted, and tapering, up to 80 cm long with acicular stipules up to 8 cm long. Flowers are cream to yellow in colour, and grouped into compound inflorescences called umbels that have linear bracts. In male plants, the umbels are found along the length of the peduncles, which are longer than the umbel rays. In female plants, the umbels are on peduncles up to 15 cm long and are made up of umbellules on short rays. Seeds usually dark brown (sometimes golden brown), 5–7 mm long.

Flowering from November–December. Flowering is irregular and infrequent (every 3–4 years).

Fruiting from January–February. Seeds are wind-dispersed.

Populations of A. aurea in the northern South Island (Marlborough and Nelson regions) show some characteristics that are different from the rest of the population, including golden brown seeds (rather than dark brown).
