Current Conservation Status

2012 - Not Threatened

Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

Male inflorescences up to 520 mm , stem 270 x 12 mm, yellow-orange; head 260 x 80 mm, lanceolate in outline; compound umbels up to 38, in 5-7 whorls, the terminal umbel smaller than the lower laterals; bracts similar to those of the female; lower compound umbels up to 80 mm long, usually as a whorl of 2 simple umbels on the peduncles, this up to 70 x 2 mm; up to 13 simple umbels with peduncles 12 x 0.4 mm, bearing up to 15 flowers per umbel, pedicels 2 x 0.1 mm. Sepals 0.3 mm; petals 1.2 x 0.8 mm, not inflexed; stamens up to 2 mm long. Mericarps 4.5 x 0.5 mm, dull pale brown, lateral ribs < 0.5 mm wide; style up to 1.2 mm.

Similar Taxa

Aciphylla montana var. gracilis (W.R.B.Oliv.) J.W.Dawson is very similar (if not conspecific) it differs chiefly by its smaller stature, with plants forming rosettes of 5 or less (rather than 25 or more), leaves up to 230 rather than 300 mm long, and by the female inflorescences being up to 400 rather 600 mm tall. In A. montana var. montana there are usually 3 but sometimes 4 leaflet pairs, in var. gracilis there are usually 2 pairs of leaflets.

Flowering

December - March

Fruiting

February to May

Propagation Technique

Difficult - requires specialist curation within an alpine house or in pots. Best in a climate prone to very cold winters and dry but cool summers. Requires free draining soils and full sun, in a moderately fertile substrate. Resents humidity and will not flower unless subject to cold treatment.
