  1. Govindarajulu et al.—American Journal of Botany 98(12): 2064-2076. 2011. – Data Supplement S1 –page 1 Govindarajulu, Rajanikanth, Colin E. Hughes, Patrick J. Alexander, and C. Donovan Bailey. 2011. The complex evolutionary dynamics of ancient and recent polyploidy in Leucaena (Leguminosae; Mimosoideae). American Journal of Botany 98(12): 2064-2076. Appendix S5. Variation in chromosome number across the informal Leucaena and Dichrostachys Groups and allied Mimosoideae, showing alternative parsimony optimizations (see Discussion) of the shift from diploid to polyploid chromosome complements among close relatives to Leucaena. Data were optimized onto Luckow et al‟s (2005) phylogeny. (A) “Slow” optimization favoring two parallel origins of polyploid chromosome complements. (B) “Fast” optimization favoring a single origin and subsequent reversal to diploid complements in members of Desmanthus and Kanaloa.
