广西植物标本馆馆藏模式标本现状与分析

ype specimens are not only the basis and evidence of plant classification, but also important basic datafor the protection and sustainable utilization of plant resources. In order to promote the full utilization andreciprocal sharing of type specimens in IBK, the species, collecting locality, collecting date and collector of themwere counted and analysed respectively. The results were as follows(1) Based on the digital information of 4 645 collections and 5 736 herbarium type specimens in IBK, there are 2 128 species of vascular plants among them,which belong to 619 genera and 170 familes (include subspecies, varieties and forms), the dominant families inthe collection of type specimens include Lauraceae, Gesneriaceae, Rubiaceae, Theaceae, Orchidaceae, Urticaceae,Liliaceae, Actinidiaceae, Euphorbiaceae, Ebenaceae, Ericaceae, etc. the dominant genera include Begonia,Aspidistra, Aristolochia, Ardisia, Ilex etc; (2) The type specimens were collected from 20 provinces, autonomousregions, municipalities and special administrative regions of China and 2 other countries. More type specimenswere collected from Guangxi (48.19%), Hainan (24.14%) and Guangdong (11.63%); (3) The type specimencollection reached the peak in the 1930s and 1950s, and the peak of type specimen naming was in the 1980s,which was related to the rise of plant taxonomy in China and the compilation and research of flora of China, theaverage shelf life for type specimens was 21 years, and the longest shelf time is 82 years. The collection anddigitization of type specimens are also discussed and prospected..
