About Mysore Thorn
A sprawling, sometimes climbing shrub with recurved prickles on young branches and leaf stalks. Its twice-pinnate leaves carry numerous small, rounded-tip oblong leaflets. Yellow flowers grow in racemes; the upper petal may bear red markings, and ten stamens are about as long as the petals. Slightly swollen smooth pods open to release four to nine black, flattened seeds. The Hawaiian flora describes a prickly shrub capable of forming large, impenetrable thickets. Repeated measures of occupied cover, stem density and native vegetation can test this pathway locally. The reviewed accounts do not quantify a Kauaʻi effect size or current island-wide extent.
