About Sacramento Bur
An erect perennial subshrub with stellate-hairy young stems. Broad ovate-to-lanceolate leaves are commonly shallowly three-lobed, three-veined from the base and irregularly toothed. Small yellow flowers have narrow petals and sepals bearing a fine subapical appendage. Rounded dry burs have backward-hairy hooked bristles. 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.
