Abstract
It is widely accepted that species are defined to be reproductively isolated groups within which natural populations interbreed [1,2]. According to this biological species concept, if reproductive isolation is established among populations, valid species could be produced. The implication is that speciation need not be accompanied by any detectable morphological changes [3]. In plants with limited movement, however, speciation is sometimes associated with distinct morphological changes, which enable plants to invade new ecological niches. The mode of speciation may hold in the case for the evolution of rheophytes.
