Specimens representing Geonoma stricta, a widespread species in the Amazon region, are variable morphologically, especially in leaf size and shape. Ordination and clustering of quantitative morphological variables indicate that the specimens can be classified in at least four different ways, but none of these is fully supported by Discriminant Analysis. The problem revolves around a group of specimens with intermediate leaf size and shape. Mapping of specimens shows that no grouping is geographically separate from any other. An infraspecific classification is not possible based on the data analyzed here. Principal Component Analysis and a test of hybridity indicate that a small percentage of specimens might be of hybrid origin.
