“…Sympatric speciation in plants not involving either hybridization or polyploidy has been the topic of recent discussion and debate (Savolainen & al. 2006a,b;Stuessy, 2006;Butlin & al., 2008;Fitzpatrick & al., 2008;Babik & al., 2009). Other modes of speciation may likewise be more common than presently recognized, but more difficult to detect than species that originated by gradual divergence in allopatry.…”

In addition to the classic allopatric model of speciation in which two lineages diverge through time, a population may “bud off” from an ancestral population and become adapted to a different habitat. The ancestral population (the progenitor or p species) remains largely unchanged in its original habitat while the population that budded off acquires novel characters and becomes the derivative (d) species. P‐d species pairs are appropriate systems for studying plant speciation because they represent recent divergence, making it more feasible to identify the few differences between the taxa and to infer possible early‐evolving barriers to gene flow. The evidence that has been used to designate species as p‐d pairs is reviewed and evaluated. P‐d species pairs are compared for several characters, with ecogeographic factors the only consistent difference between species pairs. Three genera in which p‐d species pairs have been studied in some depth are used to illustrate both the advantages and challenges of studying the process of speciation. It is suggested that there are some advantages in focusing future studies on even earlier stages of divergence, in which speciation is not yet complete, and p and d populations can be identified. Efforts should focus on ever more refined genetic analyses of differences between populations, especially factors reducing effective gene flow between them.

“…However, convincing examples of truly sympatric speciation in plants are very rare (reviewed by Keller and Seehausen 2012). Results published by Savolainen et al (2006a) on two sister species of palm Arecaceae that diverged from each other well after an oceanic island formed caused intense discussion (Stuessy 2006;Savolainen et al 2006b). The authors argued that sympatric species really do experience diverging selection due to competition for a certain type of soil.…”

“…In their response to a letter from Stuessy, Savolainen and colleagues argued that erosion on the island has been mainly coastal and equal from all sides. “Consequently, Quaternary calcarenite deposits, which created divergent ecological selection pressures conducive to Howea species divergence, have formed evenly around the island; these are so closely intercalated with volcanic rocks that allopatric speciation due to ecogeographic isolation, as Stuessy proposes, is unrealistic” (Savolainen et al , 2006b). Their rebuttal has found support in the field.…”
