About Yellow Alder
An erect bushy herb or short-lived shrub with fine appressed hairs. Pointed lanceolate leaves have irregular crenate-serrate margins and paired basal glands. Flower stalks are almost wholly united to the leaf stalks, with leaf-like bracteoles. Bright-yellow flowers develop into small capsules containing densely pitted 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.
