| Abstract: | Specimens of Malus baccata from some herbaria including the Institute of Botany,Chinese Academy of Sciences Herbarium (PE) were re-identified in light of the latest taxonomic outcome of the genus Malus Mill.and 358 valuable distribution records were selected and digitized into the geographic coordinate data.Based on these data,the updated geographic distribution is mapped using DIVA- - GIS.This distribution presents a pattern extending mainly from the northeast to southwest,and secondarily from northwest to... |
