Chromosome counts and descriptions are given for some species of the genera Babiana, Geissorhiza and Romulea in the fridaceae. On the basi of three species of Babiana reported here and elsewhere, the basic number for the genus may be tentatively set at 6 or 7. From five species of Romulea so far reported, the basic number of the genus may be set at 9. A possible triploid species is reported. One species in the genus Geissorhiza reported here has a basic number of 13. Many other species of these genera and others in the Iridaceac remain to be investigated cytologically.
