Abstract:

Clarifying plant species is the base of plant taxonomical research and also the premise of iFlora, for which investigations on plant species provide the most basal and important research materials. However, field investigations traditionally are for the flora of some regions or for collecting some kinds of plant resources, but for the local populations of species. Investigation and research of plant species on population level therefore need to be concerned and implemented in the plan of iFlora, in which “individual (specimens)(local breeding) populationplant species” will be the core clue. Different from the past, the field investigation will be targeted at local breeding population and collects morphological, ecological and genetical information as direct proof applied to taxonomical discussion and foundiation of species′ database. Furthermore we should place great importance on populations of type loaclity. Due to fragmentary type specimens and simple original descriptions, researchers have to actively consider “topotype” and “population of type locality” as the extension of “type”. Populations of type locality, which are like as “Golden Spikes” of geology, are more than just footnotes of type specimens, but provide authoritative and abundant information sources for the taxonomical research of plant species.
