Leptopelis gramineus is a species of frog in the family Arthroleptidae. It is endemic to Ethiopia and occurs on the Ethiopian Highlands on both sides of the Great Rift Valley. Common names Badditu forest treefrog and Ethiopian burrowing tree frog have been coined for it.
Adult males measure 20–45 mm (0.79–1.77 in) and adult females 40–63 mm (1.6–2.5 in) in snout–vent length; size varies considerably among populations. The dorsal colour is almost always green. Darker markings may be present but only very rarely form a triangle. There is a lateral series of large, dark brown blotches. Skin of the dorsum is rather coarsely granular, sometimes warty. Males have pectoral glands. The tadpoles are eel-shaped, heavily pigmented, and can grow to 64 mm (2.5 in) in length.
The male advertisement call is a single, deep "clack", sometimes preceded by a creaking sound.
