Description

Abundant on matipo (Myrsine chathamica), hakapiri (Olearia traversiorum) and hokotaka (Corokia macrocarpa)in dune forest.

By far the most common Macromitrium on the islands. This species ( a dubious species at best) is the only moss believed endemic to the Chatham Islands.

Still deciding if this is Flavoparmelia haysomii or F. soredians - both are present on Rekohu.

Description

Probably planted at this location as I have never seen this species in the northern two-thirds of Rekohu (Chatham Island) before - except in gardens. This is really a species of the coastal peat soils of the southern tablelands, Rangihaute / Rangiuria / Pitt Island and other southern islands of the Chatham Island group.

However, as I cannot be sure I am leaving this question open.

Two shrubs noted in regenerating forest on margin of track leading to Point Munning seal colony.

Not actually seen when I took these images - I was concentrating on the flowers right! However noted when processing images. Looks like a fly of some sort. Sufficiently interesting I am posting it to see if anyone knows what it is. Sorry about image quality...

Description

Flowering male plant - with dipteran of some sort. I stupidly realised after I took this image that there is no way anyone can confirm the species level determination - no foliage etc. So you will have to believe me on this one.

I was too interested in the flowers of this species to care to bother with the technicalities.

Common. Saxicolous on Chatham schist outcrops. Thallus lobes hollow, apices sorediate - determination based on specimens collected.

Specimens more heavily sorediate than I am used to, and I have not seen this species growing on rock before.
