Dwarf iliau
Freely branching decumbent to erect (< 7dm high) shrub with stout stems crowned by rosetted leaves. Diagnostic features of the species include free branching of the stem axis near ground level, leaves in whorls of 7-9 that join to form a basal sheath around the stem, and mostly unbranched peduncles. Flowering has been observed in June, September, October, and December.
This rare and endangered species occurs only on Kaua'i, restricted largely to the very dry ridges of Polihale and Ka'awe'iki at elevations ranging from about 275-400 m. It is found in sites receiving about 75-100 cm precipitation per year.
