Dense patch, near mono-specific, of this plant on the outlet-spillway from former farm dam (one slightly further up valley from where Gratiola pedunculata has been previously recorded).
Plants were mostly just about 30 cm tall but a few individuals were actually 39 cm tall.
Occurrence on slopes of outlet-spillway suggests the seeds floated here, and were stranded when water levels fell, after very wet spring. This area was totally submerged on 27 october: Gratiola seedlings were noted on wet muds on 19 November, barely 3 weeks later.
