About Sidastrum micranthum
A densely yellowish stellate-hairy herb or shrub with pointed broad ovate leaves and shallow heart-shaped bases. Leaves become smaller within narrow branched flower systems. Tiny pale-yellow flowers have a short projecting staminal column. Fruits have five pale-brown segments without apical beaks, containing reddish-brown seeds. Established wild occurrence warrants observations of occupied cover, reproductive plants and new recruits. These measurements can test persistence and spread. The reviewed accounts do not quantify an island-wide effect on Kauaʻi native vegetation.
