A small, mat-forming plant that grows in very wet environments. Small green ovate leaves, with white flowers, which are present from November to March. The orange-brown coma can distinguish this
Epilobium from others in New Zealand, except for the closely related
Epilobium chionanthum. To distinguish from that plant, look for small hairs all over the stems, and opposite leaves on most of the plant except for an alternating pattern near the tips. Fruiting pedicels longer than 30mm are also distinctive. ==Distribution and habitat==
