Proceedings / Indian Academy of Sciences

Abstract

Launaea pinnatifida Cass. a member of the compositae, is a runner growing on sandy sea coasts of Indian subcontinent. The plant bears yellow flowered heads and produces milky latex. The cytological study with respect to its geographical distribution has been carried out. All the collections ofLaunaea pinnatifida showed 2n=18 chromosomes. Nine bivalents are counted at diakinesis. Meiosis is normal. One or two nucleolar bivalents are noticed. Position of centromeres in the chromosomes showed variation, this may be due to structural rearrangement taking place in the chromosomes of the taxon which has been discussed.
