1. Karyomorphological studies in a garden variety of aloe suggest that it is an interspecific hybrid.
2. The diploid complement shows 14 chromosomes, of which one long and one short have secondary constrictions and are without homologues.
3. The karyotype has been discussed in relation to probable parents of the plant.
4. In majority of the dividing cells, various types of mitotic abnormalities during metaphase and anaphase have been recorded.
5. The mitotic imbalance is in all probabilities due to hybridity.
