New Zealand: flax
Along with ferns, the other practically ubiquitous type of native plant one sees in New Zealand is flax. At least that’s what the British called it after they arrived and found the Māori using the fibers of the plant to make cloth, just as the Europeans used flax to make linen. The Māori call these members of the lily family harakeke, the most common species of which is Phormium tenax.
On February 12, after driving a few minutes west from the site where I took the picture of sand dunes that you saw last time (and you can still see them in the background this time), I came to the Arai-Te-Uru Recreation Reserve, where I was able to portray these New Zealand flax plants in the stage after they’ve produced and shed seeds.

New Zealand: my first substantial sand dunes
On our way to Tāne Mahuta on February 12th (which schoolchildren in the United States once knew as Lincoln’s Birthday), we drove along S.H. 12 through Opononi and nearby Omapere. The road in that area followed the southern shore of Hokianga Harbour, and as we approached the Tasman Sea I saw on the other side of the esturary the first substantial sand dunes of the trip. Unfortunately there was no easy way to get to them, and contact with large dunes would have to wait a couple of days.

A double-headed Mexican hat
I’d been keeping my eye on a stretch of median in Morado Circle in the Great Hills neighborhood of Austin where I live. At some point the median had been mowed, but now in the spring the vegetation was reasserting itself. A week ago I noticed some Mexican hat plants (Ratibida columnifera) coming up, and when I drove by on March 26th I saw that several were already flowering. The next day I went and sat myself down with them. The flower head shown here caught my attention and I took some pictures of it. Only when I went to look from the opposite side did I discover another central column jutting out at roughly a right angle to the one shown here. In other words, this was an unusual flower head, a twin. While I was still there I didn’t get the impression of fasciation, but in this photograph the stem does seem a little wide and flattened, so perhaps fasciation explains the doubling-up after all.
The two adjacent sets of ray flowers formed a broad collar that isolated one central column from the other. I looked from various angles but couldn’t find a good way to photograph the two columns together. In the end, just for the sake of documentation, I took the picture below.

New Zealand: Neptune’s necklace
Something else that intrigued me at Cable Bay on February 13th and at other places on other dates was a type of brown algae known by the imaginative names Neptune’s necklace, Neptune’s pearls, sea grapes, and bubbleweed (Hormosira banksii).

New Zealand: Cable Bay
In the Cable Bay section of Doubtless Bay on February 13th I focused on the rocks and shells along the beach. In particular, I was intrigued by clusters of small black mussels that looked to me as if they could be pieces of obsidian.
I take the genus to be Xenostrobus, but if anyone knows for sure, please chime in. Here’s a closer look at a group of these mussels.

New Zealand: Doubtless you’ve heard of Doubtless Bay
Doubtless you’ve heard of Doubtless Bay if you’re from or have visited New Zealand’s Northland region. Otherwise you well may not have heard of that body of water, which reputedly got its name when Captain Cook sailed past it and wrote in his diary that it was “doubtless a bay.” We drove along the shore of Doubtless Bay on February 13th and stopped in several places. The one shown above is Coopers Beach, where I was intrigued by the way a stream etched itself into the sand as it flowed into the bay. The flowing water occasionally caused bits of the stream’s sandy banks to crumble, creating the jagged margins you see here.
Looking in the opposite direction, I saw one of my old friends from the first visit to New Zealand, a pōhutukawa tree (Metrosideros excelsa).

Wild garlic buds opening

New Zealand: pīngao
On February 13th we visited the Puheke Reserve on the northern shore of the Karikari Peninsula in the Northland region of New Zealand. My attention was soon drawn to a plant that on the whole grew toward the sea even as individual tufts tended to curl back in the opposite direction. The best I can tell, the plant is pīngao, a sedge that botanists classify as Ficinia spiralis. It’s endemic to New Zealand but animal grazing and the spread of a non-native grass have continued to curtail this sedge’s historical range.

New Zealand: still more things than the glacier at the glacier
When we visited the Franz Josef Glacier on February 20th, my attention leapt not only to the glacier and nearby waterfalls, but to the many rocks in the area. In particular, lots of rocks were coated to varying degrees with a fine red-orange lichen, shown above, that made the stone surface it was on seem painted.
In many cases, as you see below, mosses vied with the reddish lichens for territory on the rocks.
