A 2007 report estimates 70 remaining individuals divided among seven occurrences in the upper elevations of the Koʻolau Mountains. The plant grows on top of ridges, in open, windy habitat within the cloud zone.[4] The occurrences have been separated and isolated by habitat fragmentation.[1]
This Hawaiian lobelioid is a shrub growing 30 to 60 centimetres (12 to 24 in) tall and producing white flowers.[4]
