Small trees or shrubs, usually spiny, with persistent coriaceous simple Lvs. having prominent netted veins and wingless or very narrowly winged petioles jointed at base of If. : fls. usually pentamerous, with the stamens free or united into a tube, twice as numerous as the petals; ovary 3-5- celled, with 1 or 2 ovules in each cell: fr. like a small orange with a lemon- like skin. In the typical species, the pulp-vesicles fill the segms., but in some dry-fruited species they are rudimentary; these species constitute the subgenus Rissoa.—Twelve or 15 species are known, ranging from India through the Malayan peninsula to Austral. | Small trees or shrubs, usually spiny, with persistent coriaceous simple Lvs. having prominent netted veins and wingless or very narrowly winged petioles jointed at base of If. : fls. usually pentamerous, with the stamens free or united into a tube, twice as numerous as the petals; ovary 3-5- celled, with 1 or 2 ovules in each cell: fr. like a small orange with a lemon- like skin.
