Documented chromosome numbers 1999:1. Chromosome numbers and pollen diameter variation in Thelesperma (Asteraceae)



Documented chromosome numbers 1999:1. Chromosome numbers and pollen diameter variation in Thelesperma (Asteraceae)



SIDA Contributions to Botany 18(3): 909-925



Diploid and tetraploid chromosome numbers and pollen measurements are reported for 95 collections from five taxa of Thelesperma (Asteraceae). These chromosome counts include the first 17 diploid (2x) reports for T. megapotamicum var. ambiguum. A correlation between ploidy level (2x, 4x) and pollen diameter (mm) is found in diploid and polyploid plants of T. megapotamicum and T. simplicifolium. In both taxa, multivalent configurations (IV, V, VI, X) are found.
