Urtica dioica ssp subinermis in a Bure fen. Likely the product of introgression of Common Nettle Urtica dioica into Fen Nettle Urtica galeopsifolia. Long grey leaves, high lowest flowering node, pubescent stems but stinging hairs thinly scattered throughout. True galeopsifolia appears extinct.

Am I correct to assume these are undeveloped florets on this meadow foxtail? Or is it caused by something else? I have seen these before but never really knew what they were. @bigmeadowsearch.bsky.social

Happy world bee day! New research published in NeoBiota has found that the Western honey bee—an introduced species to Australia—and the devastating, invasive plant fungus known as myrtle rust (Austropuccinia psidii) may have formed a mutually beneficial relationship known as "invasional mutualism.

Another random botanical post: kikuyu seeds from a lawn in Hamilton. Not fully mature but getting there. Sometimes species epiphets are very descriptive, the seeds are 'clandestine'. When seed is grown commercially fields are mulched then seeds are extracted using suction.

First case of resistance in NZ for spurrey, to chlorsulfuron in herbicide tolerant brassicas! Will need to repeat the dose-response to get an accurate ED50 estimate.
Spurrey plants from two susceptible (above and below) and a resistant (middle) population with doses doubling from the left (except 0x on far left). Columns have the same dose - the resistant one starts with a dose 1/2x the label rate.A photo of a resistant spurrey taken a week or so ago.

Good article, but the framing is wrong. There is not a dearth of interest in taxonomy. There is a scarcity of funding and positions, which is a deliberate choice by funding agencies and institutions. The youth love taxonomy! It's the olds that are failing to meet their passion!

The origins of the Move On orders are from Ham East National MP, Ryan Hamilton - former Hamilton City Councillor whose council colleagues are setting up bylaws of a $20,000 fine for basically being visibly homeless. It begs the question, who's allowed to ask for money on the street and who isn't?

I wasn't involved in this project but I've been a keen observer. Celery weed is a huge cost to Council's and landowners around the country for channel maintenance. Appropriate riparian planting shades out celery weed and can significantly reduce maintenance costs.
Drain 1. 2015. Before planting. 2018. Drain was mechanically cleared and planted. Also celery weed grows slowly in winter. 2021. Summer and no celery weed until further downstream where planting stops. 2026. Despite appearances, still glowing free below. A good reason not to plant harakeke right on the edges. They get massive and can restrict flow in storm events or blockages if they fall in.
