Abstract
Geographic variation in theDicanthelium aciculare complex was studied by principal components analysis. Few of the attributes analyzed show high correlations with one another, but pubescence patterns are of value in the discrimination of taxa. Sharp differences between phenetic clusters are restricted to one or two geographical regions. When viewed as a whole the complex forms a mosaic of variation patterns and the boundaries between phenetic clusters fade. The complex is reduced to two species,Dichanthelium aciculare (Desv. ex Poir.) Gould & Clark andD. consanguineum (Kunth) Gould & Clark.Keywords
