The bases of the leaves are wedge-shaped to tapering. Its petioles are 3–13 millimeters long. Its many flowered, branching Inflorescences occur at the junction between the leaves and stem. Each flower is on a pedicels that is 3–6 millimeters long. The pedicels have bracts that are 1 millimeter long. Its flowers have 5 hairless sepals that are connected at the base with broad, egg-shaped lobes that are 0.7–1 by 0.7–1 millimeters. The sepals have pointed tips. The 5 hairless, white to rose-colored petals are fused at their base to form a 0.8–1.2 millimeter tube with oblong lobes that are 2.8–3.4 by 1.1–1.6 millimeters. The petals have rounded tips. The flowers have a ring-like structure between the petals and its stamen called a corona. Its corona has 5 thread-like lobes that are 2–3 millimeters long with appendages at the top that point inwards. Its stamen have very short, 0.1 millimeter-long, filaments and 0.5–0.6 millimeter long anthers. The anthers have a recurved appendix at their base. The connective tissue between the chambers of the anther extends up into a rounded tip. Its pistils have broad, cone-shaped stigma.
