Abstract: 
Two new types of haustoria were found in many representatives of Rhinanthoideae [27 taxa of Rhinanthus, Pedicularis, Melampyrum, Odontites, Euphrasia, Bartsia and Lathraea]. Metahaustoria are stimulated by host roots but lack contact with them. They develop a massive haustorial core with a large- and a smalled-celled portion, but little vascular core. In very old metahaustoria the vascular core is much enlarged and numberous tracheal elements develop in the reduced haustorial core and cortex. Wart-haustoria are very small, occur only in the upper portions of the root system, and have host contacts. Vascular and haustorial core, and the endophyte are lacking, the intrusive cells are usually not endogenous, but rather roothair-like. Wart-haustoria may represent reduced and partly inhibited normal haustoria.
