Jean H. Burns. 2008. Demographic performance predicts invasiveness of species in the Commelinaceae under high-nutrient conditions. Ecological Applications 18:335–346.

Appendix B. Matrices for models of the demography of invasive and noninvasive Commelinaceae.

TABLE B1. Matrix models for eight species of Commelinaceae, four invasive species and four noninvasive congeners. Separate models were created for each of four maternal growing environments. For Commelina benghalensis seeds were of different types (e.g., CH-D: chasmogamous, dehiscent).
