Erect, single-stemmed monocarpic rosette shrub, or, if branched, polycarpic and erect or decumbent; flowering plants commonly up to 2 m high. Diagnostic features of the species include green, 5-11-nerved, narrowly elliptic-ligulate leaves which are broadest above the middle, and pappus of disk florets mostly 1-2 mm long. Flowering occurs from June to January, apparently peaking in August.
This species occurs on E Maui and W Maui, mostly in and on the perimeter of bogs at elevations ranging from about 1,200 to 2,050 m. It occurs in sites receiving about 150->1,000 cm precipitation per year. Although occasionally locally abundant, populations are usually very restricted in area and of limited distribution.
