Aliso: A Journal of Systematic and Floristic Botany
Since our goal was to determine characteristic differences between Bromus richardsonii and B. ciliates, a discriminate analysis (DA), principal components analysis (PCA), multidimensional scaling (MDS), bivariate analysis, and an amplified fragment length polymorphisms (AFLP) analysis were undertaken on 93 herbarium specimens and 31 field-collected populations. A cytological survey of B. ciliates, B. richardsonii, and B. mucroglumis confirm previous reports that the first species is diploid (2n = 14) and the latter two are tetraploid (2n = 28). All taxa were correctly classified in the DA and important characters for each of the species were identified. Bromus …
