中国苦苣苔科植物的多样性与地理分布
Diversity and distribution of Gesneriaceae in China
摘要
Abstract
The species catalogue is the basis of biodiversity conservation studies. We collated the latest Gesneriaceae from China found in recent years. Based on these collection data, we analyzed the diversity in each genus and the distri-butional patterns in provincial level. There are 671 species ( including infraspecies) , 44 genera of Gesneriaceae in Chi-na, including 573 endemic species, which accounts for 85.39% of total species. The top ten genera are Primulina (180 species), Oreocharis (122 species), Petrocosmea (39 species), Hemiboea (39 species), Aeschynanthus (38 species), Didymocarpus ( 35 species) , Petrocodon ( 31 species) , Lysionotus ( 31 species) , Paraboea ( 28 species) and Henckelia (22 species). The following ten areas and provinces are rich in Gesneriaceae:Guangxi (260 species, 33 genera), Yun-nan (236 species, 30 genera), Guizhou (96 species, 28 genera), Guangdong (93 species, 17 genera), Sichuan (85 species, 21 genera), Hunan (58 species, 13 genera), Tibet (39 species, 9 genera), Hubei (29 species, 15 genera), Fujian (26 species, 13 genera) and Jiangxi (25 species, 9 genera). Endemic species are rich in genera including Prim-ulina (178 species), Oreocharis (119 species), Petrocosmea (37 species), Hemiboea (35 species), Petrocodon (30 species), Didymocarpus (29 species), Lysionotus (23 species), Paraboea (19 species), Aeschynanthus (19 species) and Henckelia ( 11 species) . Our results indicate that Primulina has the highest species diversity and the endemism in China, followed by Oreocharis, Petrocosmea, Hemiboea, Petrocodon and Lysionotus. South and Southwest China are the centers of Gesneriad diversity, containing many representative and narrow-range endemic species. Within South and Southwest China, the limestone areas have the highest species diversity and percentage of endemic species. Gesneriaceae has high diversity in China, so that more taxonomic and phylogenetic studies to be done in the future, as well as conser-vation and sustainable utilization.关键词
