Cyanea undulata

This Hawaiian lobelioid is a shrub which can exceed three meters in height. The leaves have wavy edges and the flowers are yellow.[4]

The plant was first described in 1909 and then it was not seen again until it was rediscovered in 1991. In 1994 there was a single population containing 28 plants. By 2006 the population was in poor shape, with a single mature plant and a few juveniles remaining.[2]

The species has become rare because of habitat degradation by feral pigs, exotic plant species, and damage to plants caused by rats and slugs.[2]
