Chromosome Numbers in Chelone (Scrophulariaceae)
Cooperrider TS and McCready GA. 1970. Chromosome Numbers in Chelone (Scrophulariaceae). Brittonia. 22(2):175-183
ABSTRACT: Meiotic and mitotic counts for all major taxa within Chelone show a euploid series: 2n = 28, 56, 84. A base number of x = 14 is suggested. The distribution of numbers supports some previous taxonomic decisions. It raises questions about others, particularly those involving the C. glabra-C. obliqua complex. A root-tip technique involving digestion by "Pectinase" is described.
