Union Between Host and Parasite in higher plants

    Abstract

    ON this subject, Schumacher and Halbsguth. have recently published an interesting and suggestive paper1. Their observations are based on extensive studies of species of Cuscuta and Orobanche on a wide range of host plants; with the union of Cuscuta and its host, particularly, they have made use of techniques which permit the recognition of protoplasmic connexions, usually freezing the material, cutting on the sliding microtome and then transferring immediately to iodine potassium-iodide solution. Afterwards. the walls were swollen and the connexions stained by a modification of Meyer's pyoctannin method.
