Summary The chromosomes of sixteen species of nine genera of Lauraceae were studied morphologically at interphase, prophase and metaphase. The chromosomes of Cassytha filiformis were found to show different morphological characteristics in comparison with the other fifteen species, although the basic number of its chromosomes was the same, i. e. , x = 12. The karyomorphological evidence in these species coincides with the proposal of Melchior (1964) to divide the Lauraceae into two subfamilies, Lauroideae and Cassythoideae.
