Brittonia Aims and scope Submit manuscript

Summary

Chromosome counts for 10 taxa of Texas Compositae are presented for the first time. These include first reports for the following genera:Chrysopsis (x = 5),Bahia (x = 12),Amblyolepis (x = 19) andTetragonotheca (x = 17). Meiotic chromosome counts from prophase material ofChrysopsis pilosa showed 3 bivalents and an apparent ring of 4. Meiosis in species of the remaining genera appeared completely normal. When appropriate, this chromosomal information has been related to taxonomic problems.
