Abstract

Karyotypes of two species of Fortunatia and three of Camassia are described. F. biflora, C. leichtlinii subsp. suksdorfii, C. cusickii and C. quamash have the basic chromosome number x = 15 and F. arida has x = 17. The genome sizes of both species of Fortunatia are three times larger than those of the three species of Camassia. Heterochromatin amount and genome size are discussed in relation to the evolution of both genera.
