Summary
Mitosis in endosperm of Haemanthus katherinae was studied in vitro by the use of 16 mm time-lapse microcinematography. In several cells, chromosomal fibres were seen in phase contrast microscope. The fibres are more convergent in late metaphase and anaphase than in prometaphase. There exist two distinct fibre attachments at each daughter kinetochore, i.e. there are four in metaphase chromosome.
Details of the division of a nearly cytoplasm-free mitotic apparatus are also reported as well as some data concerning the elongation of the spindle and activity of the phragmoplast.
