Abstract
The influence of chloral hydrate on endosperm cells of Haemanthus katherinae was studied. Four types of mitotic disturbances were described: a) Normal bipolar mitosis with one or few chromosomes lying out of the metaphase plate. Bipolar mitoses are sometimes arrested in anaphase and followed by the formation of a restitution nucleus. b) Tri — or multipolar anaphases. c) “Diffuse anaphase” movements i.e., active anaphase movements without distinct poles followed by the formation of multipolar phragmoplasts and cell walls. d) C-mitosis resembling the effect of colchicine. Some aspects of the described phenomena were discussed.
