Trichomanes reniforme, “Raurenga” (Maori) or kidney fern

This is the 17th photo in the series on Rangitoto Island. Nearing the end now – about time I think…

As we climbed Rangitoto we were surprised at all these little ferns that we thought were dying. They were quite plentiful closer to the base of the island, and when we returned from the summit we stopped to look closer at them. We were pleased to find out that these Kidney Ferns weren’t dying at all.

Conditions on Rangitoto are extreme. To survive the high temperatures plants have developed a kind of survival kit – a combination of features that enables them to make the most of their situation. Colour, texture, size and shape all play a part in enhancing a plant’s chance of survival.

A shrivelling action allows these Kidney Ferns to reduce their surface area. This reduces the moisture lost and susceptibility to heat. On hot days Kidney Ferns shrivel up like potato crisps. Their leaves return to normal size when conditions are moist. Although these filmy ferns are very delicate, they can survive extended dry periods by curling its fronds up tightly and then opening them up again as soon as rain falls.

There is The Kidney Fern Walk that leads to a soft green glen of delicate, translucent kidney ferns. Trichomanes reniforme, Raurenga or kidney fern. An endemic species with distinctive, kidney-shaped fronds with veins that repeatedly fork (dichotomous) and sori crowded on the margin. This fern is widespread in the North Island and the west coast of the South Island on the forest floor, rocks or as an epiphyte.

I have posted another picture of the Kidney Ferns in Workshop.

Hi Janice! The green colors are brilliant and the focus on the leafs is very good. You have some burnt spots in the photo (righthand side) though. TFS!

I love your stories from Rangitoto Jancie! Looks like it has got suitable climate for me ;-) I like to read books about biology of plants and its adaptations to hard conditions but I see it first time in 'real' NZ world :-) Thank you!

Yes.I used to worry about all the plants I thought were dying too.
Its amazing how the forest regenerates itself when the rains come again.It gets quite brown in the summer.
Good post.

Bonne exposition avec de beau contraste de couleurs. L'éclairage est subtil et juste.

Félicitations et bonne journée.

Janice, Great sharpness & detail. Love the textures I see. Interesting note/plant. TFS!

Technical quality:****
Wow factor:**

Nice shot Janice, but a bit messy, and hard to read. Good details and colours.

Ah, the green... lovely shot of the green, good detail of the leave, but I think the bg is very busy. Hey, are you still using your Sony and not your Canon? TFS

Hi Janice, very interesting subject and a great note. You could try getting down to the level of these plants and isolating just one of them. As it stands this is hard on the eye, I find my eye searching around for something to latch onto, I hope you see what I mean? Good work.

Janice, vivid colors and nice composition.

The green shades are excellent. Excellent sharpness.

Very interesting! I have never seen those ferns. Are they unique for NZ? The pic is very good and your note very informative!

Thank you for the great notes and the excellent image Janice! Interesting plant I would have thought that the plant was dead too all shrivel up like that! Very sharp and interesting composition.
