About Sida planicaulis
An erect-to-spreading subshrub with alternate leaves in two ranks. Lanceolate-to-ovate blades have finely serrate margins almost to the rounded unequal base and narrow curved ribbed stipules. A representative light-orange flower form with yellow centers occurs in dense axillary groups. Dark wheel-like fruits generally have seven to ten one-seeded segments with paired slender apical awns. 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.
