Epilobium pycnostachyum, or scree epilobium, [2] is a species of willowherb that is endemic to New Zealand. It grows exclusively on scree slopes on mountains.
A small herb with a few branches that spread out and then up. The leaves are a dull green, and glabrous and have deep teeth on the margins. The flowers are white, [3] or red and pink. [4]
The seeds are wind-dispersed. [4]
Epilobium pycnostachyum is known from both the North and the South Island. [5] [3] It is restricted to mountain ranges, where it grows in scree fields and unstable, rocky environments. [3]
Pycnostachyum means 'densely spiked'. [4]
It was described by Heinrich Carl Haussknecht in 1879. [3] The type specimen is from Whitcombe's Pass, on the South Island of New Zealand. [3]
