Stomata are confined to the lower leaf surface, where they are surrounded by papillae formed by adjacent epidermal cells. In Akania, several stomata form macroscopically visible clusters covered by such papillae (Solereder 1899). Stomata of Bretschneidera are evenly scattered, each being surrounded by interconnected papillae (Radlkofer 1908).
Both idioblastic and stomatal myrosin cells have been reported for Akania and Bretschneidera (Radlkofer 1908; Jergensen 1987, 1995).
