The leaves are a glossy green color. From spring to summer, it produces multiple dark pink five-petaled flowers on the tips of long, slender flower stalks that grow between the rhizome leaves. The genus includes the potato sorrel (Imo sorrel, scientific name: Oxalis articulata) and Murasaki snails (purple striped eater, scientific name: Oxalis corymbosa ) (petal color peach) and are similar to them. The anther color of the stamens in the center of the flower of the potato katydid (O. articulata) and the red katydid (O. brasiliensis) is yellow, whereas the anther color of the purple katydid (O. brasiliensis) is white. O. articulata and O. brasiliensis have a darker color at the center of the flower, whereas O. brasiliensis has a lighter color at the center. The difference between O. articulata and O. brasiliensis is that the leaves of O. articulata are larger and less shiny in relation to the flowers, while those of O. brasiliensis are smaller and more shiny. O. brasiliensis' petals are rounded while O. articulata's are elongated.
