Anyway, the most common by far Austroblechnum on the Chatham Islands - seen here in peaty turf - but also common in grassland, along cliff tops and in forest.

Tricky - I have grown this morph from this location before, assuming it was G. aggregatus only to find it grew out into classic G. micranthus (confirmed by DNA sequence and chromosome counts). So I am calling this G. micranthus - New Zealand Gonocarpus still need a further taxonomic revision in particular to ascertain where G. aggregatus starts, G. incanus stops and what exactly is G. montanus!

Whatever Gonocarpus people want to call this, this plant is very common on the sheep and cattle browsed peaty turf. On this day all plants seen heavily flowering...
