Differentiating between Common Yellow Woodsorrel and Slender Woodsorrel (Oxalis dillenii) can be tricky. Looking at the seeds of the plant is the best way to identify these two species. Slender Yellow Woodsorrel has seeds that are brown, with prominent white ridges. In contrast, the seeds of Common Yellow Woodsorrel are plain brown. Checking the hairs on the stem is another way to separate the two species. The stem hairs of Slender Yellow Woodsorrel are appressed, while the stem hairs of Common Yellow Woodsorrel are dense and spreading.
