Contribution a L'Etude Cytotaxonomique des Rumex—II. Le Genre Bucephalophora Pau

Pages 203-206 | Received 22 May 1974, Published online: 30 Jan 2014
 

RESUMÉ

Le caryotype de Bucephalophora aculeata (L.) Pau (2 n=16) a été étudié en détail.

Il a été comparé avec le caryotype de base du genre Rumex sensu stricto et avec des données obtenues pour le genre Acetosa. Nos observations cytologiques justifient la création d'un genre indépendant pour l'espèce Bucephalophora aculeata. L'hypothèse d'une évolution par aneuploïdie est évoquée.

SUMMARY

The karyotype of Bucephalophora aculeata (L.) Pau (2 n=16) was described in detail.

It was compared with the basic karyotype of Rumex sensu stricto and with data obtained in the genus Acetosa. Our present cytological observations account for a separate genus for the species Bucephalophora aculeata. Evolution by aneuploid (loss of chromosomes) processes is discussed.
