Summary
-
1.
The chromosome numbers in three Indian speciesFossombronia himalayensis Kash.,Petalophyllum indicum Kash. andSewardiella tuberifera Kash. have been investigated. The diploid chromosome number in each case is 18 but the morphology of the chromosomes in each species is different from the other.
-
2.
The basic chromosome number in the familyCodoniaceæ appears to be 9.
-
3.
Polyploidy is of rather rare occurrence in the evolution of new species in the family.
