I can't decide on B. verna or B. orthoceras
Petit champ près d'une piste cyclable
Loaded up especially for John van den Hoeven (see http://naturewatch.org.nz/observations/2353510). The weather and time finally allowed a lawn massacre (getting into a hay paddock) - at least for now this plant has had a hair cut. It will rise again I am sure.
Stems and leaf margins distinctly hair, upper stem leaves pinnatifid. Weed in lawn, rarely gets to flower before it gets scalped by lawnmower - but I have been a tad remiss with mowing of late so it got to flower....
Not 100% on the ID
I'd welcome some help with an ID for this cress-like plant appearing as a weed alongside the Field Centre.
This yellow flower is part of a plant and is an oval shape. It was found by the water. They form in bunches.
These were popular in this area. Also by the water.
On waste-ground. My thanks to Tom Belton (Department of Conservation, Hokitika) for ID.
