福建苔类和角苔类植物最新名录与区系分析

福建地处亚热带，其维管植物多样性已经有过广泛的研究，但其苔类和角苔类植物的多样性却鲜为人知。在本研究中，作者基于先前的苔藓植物文献报道和近期的野外工作以及对华东师范大学标本馆部分馆藏标本的研究结果，编写了福建苔类和角苔类植物的最新名录。福建共有苔类植物41科79属351种，角苔类植物1科4属6种。本研究新增福建苔类新记录82种。福建苔类和角苔类植物区系主要由细鳞苔科（94种），耳叶苔科（32种），羽苔科（25种），扁萼苔科（23种）和指叶苔科（21种）等一些热带和亚热带的大科组成。除种数较多的属以外，63个属的种数不足5种，其中包括33个单种属。福建苔类和角苔类植物的区系地理分布主要以东亚、热带亚洲和北温带成分为主。福建特有种仅Solenostoma parviperianthum一种。与台湾相比，尽管两地植物间具有较高的相似性，福建在苔类和角苔类植物的多样性以及特有成分上都还远不及台湾丰富。

Liverworts and Hornworts of Fujian, China: an Updated Checklist and Bryofloristic Accounts

Fujian, located in the subtropics of southeastern China, is a province on the southeast cost of China directly across from Taiwan. Although the diversity of vascular plants of Fujian has been extensively studied, the diversity of liverworts and hornworts of this province is poorly understood. In this study, an updated checklist of Fujian liverworts and hornworts is provided based on published bryological literatures and our recent fieldwork as well assome specimens deposited in the herbarium of East China Normal University. The liverwort and hornwort flora of Fujian consists of 351 species of liverworts belonging to 79 genera in 41 families, and six species of hornworts belonging to four genera in one family. The present paper contributes 82 species as new records for this province. Tropical and subtropical families, such as Lejeuneaceae (94 spp.), Frullaniaceae (32 spp.), Plagiochilaceae (25 spp.),Radulaceae (23 spp.) and Lepidoziaceae (21 spp.) are the primary components of Fujian liverwort and hornwort flora. Sixty-three genera are represented by fewer than five species including 33 with only one representative species.The areal-type of Fujian liverworts and hornworts is mainly dominated by the East Asia element, the Tropical Asia element and the North Temperate element. Only one species, Solenostoma parviperianthum, is endemic to this province. In comparison with Taiwan, despite the close affinity, the diversity and the endemism of Fujian liverworts and hornworts are still far behind those of Taiwan.
