#1919 - Acaena sp. - Bidibid

One last one from @purrdence​’s trip up to Aoraki Mt Cook.

Biddy-biddys (piripiri in Māori) is a genus of some 50 species mostly found in Australia, New Zealand and South America, although one made it to Hawaii and one to California. On the other hand, some of the Acaenas have managed to become weeds in other parts of the world, which is highly unusual for a NZ species. Their spread is aided by the long arrow-head barb on the seeds, which attach to fur or socks. Presumably they also attach to feathers, since the only native land mammals in New Zealand were three species of bat, and one of those is probably extinct.

#2834 - Acaena novae-zelandiae - Bidgee-Widgee

And ANOTHER species of Acaena.

AKA red bidibid, buzzy and piri-piri bur. Despite the epithet, also found in Australia and Papua New Guinea.

First formally described in 1871 by English-born botanist Thomas Kirk. The New Zealand government commissioned him in 1884 to report on the forests of the country and appointed him as chief conservator of forests the following year. He was instrumental in setting aside some 800 000 acres as forest reserves by 1888. He was also the author of 130 botantical papers, and was highly regarded for his knowledge of Aotearoan flora.

#2680 - Acaena anserinifolia - Silverweed Bidibid

AKA hutiwai, and piripiri, Acaena pusilla and Acaena viridior. The binomial is derived from the resemblance to Argentina anserina, also known as silverweed or silver cinquefoil.

Another Acaena species. This one is abundant on all the Aotearoan islands, from lowland to subalpine forest margins and in shrublands. It's also naturalised on the Auckland and Campbell Islands.

#2663 - Acaena profundeincisa

Not from Aoraki - it is, in fact, back from the North Island, at the alpine village halfway up Mt. Ruapehu. I only just got an ID on it, from somebody who had noticed the unusual Acaena in the area before, and presumes it got there on somebody's sock.

#2662 - Acaena inermis - Spineless Acaena 

Another species of New Zealand Burr, although this one has been introduced to the UK, and has a cultivar grown as a ground cover.

Aoraki / Mt Cook, Aotearoa New Zealand.
