Ovary 1-celled, the placentae intruded; style 2-cleft or 2-parted, its lobes filiform, stigmatic along their inner sides. Capsule ovoid or globose, 2-valved, many-seeded. Seeds small, reticulated. [In honor of L. and C. Sabbati, Italian botanists, according to Salisbury, Parad. Lond. pl. 32, therefore Sabbatia, though Adanson's spelling was Sabatia.]
