Abstract

Meiotic and mitotic counts for all major taxa withinChelone show a euploid series: 2n = 28, 56, 84. A base number ofx = 14 is suggested. The distribution of numbers supports some previous taxonomic decisions. It raises questions about others, particularly those involving theC. glabra-C. obliqua complex. A root-tip technique involving digestion by “Pectinase” is described.
