In cushion bog forest margin, a single individual of the hybrid between Chionochloa conspicua and C. rubra. See this observation: https://inaturalist.nz/observations/65613719
Fitting that this species is flowering on rewarewa near to the memorial for the Waikato botanist Michael C. Gudex. Seen on several emergent trees (pukatea and rewarewa); unfortunately images from phone and at a distance.
