Functional utrastructure of Genlisea (Lentibulariaceae) digestive hairs.

abstract：BACKGROUND:The origin of new species and of new forms is one of the fundamental characteristics of evolution. However, the mechanisms that govern the diversity and disparity of lineages remain poorly understood. Particularly unclear are the reasons why some taxa are vastly more species-rich than others and the manner i...
