About Round Pepperweed
A small, much-branched perennial shrub with smooth dark-purple young branchlets and green, slightly fleshy leaves crowded near shoot tips. Tiny flowers have four white spoon-shaped petals and six projecting stamens. Flattened round seeds are shiny reddish brown and have a narrow pale membranous wing. This native shrub is a component of Hawaiian vegetation. Monitoring mature plants, new recruits and occupied cover can assess persistence and replacement. The reviewed accounts do not establish a measured Kauaʻi population trend or quantify an ecosystem effect.
