Lepuropetalon and usually face upward. They are large compared to the rest of the plant, 2 to 3mm in diameter with male and female parts both present and functional. The calyx consists of five broad, often unequal sepals that are joined in the lower part to form a floral cup that encloses the lower half of the ovary and is thickened along its fissures to form five ribs. The sepals persist beyond the maturity of the fruit. The petals are scale-like, white and barely visible, on the rim of the floral cup between the sepals, or sometimes absent. They die but
Hibiscus acetosella plant and are generally the size of a small child's hand, about 10×10 cm. They tend to be alternate, simple, and deeply cut with crenate or jagged edges. Leaf color is observed as a dark maroon to a patchy red/green appearance. Stipules are linear, measured approximately 1.5 cm in length. Both stems and petioles (3–11 cm in length) are smooth or generally free from hair. Acetosella is further divided into a section called Furcaria, which is a group of approximately 100 species that have non-fleshy calyx or sepals. The sepals contain 10 veins, 5 of which run to the apices
