Description

Delissea rhytidosperma, a Hawaiian lobelioid, is a shrub which grows up to 2.5 metres (8.2 ft) tall. The leaves have lance-shaped or nearly oval blades up to 19 centimeters long. The tubular flowers have greenish or purplish petals and distinctive hairs next to the anthers.[5]
The plant's natural habitat is rocky cliffsides in moist forests dominated by Acacia koa. This habitat has been destroyed and degraded by the action of feral pigs, goats, and mule deer,[4] and by exotic plant species. Germination and establishment are further limited by non-native rodents, snails, and grasses.[6]
