So siehtman hier also gleichsam eine Arbeitsteilung im Haustorium angedeutet,insofern als der Kern den eigentlich zerstörenden, Nahrung aufnehmendenSaugfortsatz bildet, der Rindenkörper dagegen das Haftorgan, die An-heftungsfalte, darstellt, welche, wie hier in der Zeichnung, bei einerdicotylen Wurzel der Rinde aufliegt und einfach ist, oft aber auch,namentlich bei dünnen Monocotylenwurzeln nach innen zu mehrere ^) Über den Bau und die Entwicklung parasitischer Phanerogamen in Prings-heims Jahrb.

Erst späterwerden dann bisweilen innerhalb des Auisenlappens ein zweiter unddritter angelegt (Fig. 62 2 a), und erst wenn die Anheftungsfalten dieWurzel der Nährp£anze fest umfafst haben, beginnt der Kern ein-zudringen. Wenn nun ein solches Haustorium nicht sofort eine passendeNährwurzel erreicht, so wächst es zu einem kleinen, gekrümmten Zweigaus, der sich zum Haustorium umbildet, wenn er in noch meristema-tische
