福建省野生兰科植物区系研究

福建省共有野生兰科植物61属134种(含变种)，其中中国特有种27种。种数在5个以上的有石豆兰属、兰属、虾脊兰属、羊耳蒜属、斑叶兰属、玉凤兰属、舌唇兰属和石斛属。福建省野生兰科植物属、种的地理成分可分别划分为15个和14个分布型(变型)，其中热带亚洲(印度马来西亚)分布及其变型分别占总属、种数的34.4%和22.4%，热带分布属、种分别有44属、73种，占绝对优势。与邻近地区相比，福建省野生兰科植物与广东共有属、种最多，分别有48属、97种，其次为江西和浙江。福建省野生兰科植物区系具明显的热带性质，地理成分具有明显的从热带向亚热带的过渡性，但组成比较简单，缺少本区特有种，不是近代兰科植物种系的分化中心。

A floristic analysis of Orchidaceae in Fujian province, China

The floristic composition and element of the orchid flora in Fujian, China were analyzed, and the affinities with its neighbor regions, such as Guangdong Province, Jiangxi Province and Zhejiang Province, were discussed as well. The orchid flora in Fujian consists of 61 genera and 134 species (including varieties) , of which 27 species are endemic to China. The main genera are Bulbophyllum, Cymbidium, Calanthe, Liparis, Goodyera, Habenaria, Platanthera and Dendrobium in this area, all of which have more than 5 species. The areal type of genera or species of the flora could be divided into IS or 14 types and subtype, respectively. Among them, the tropical Asian (Indo-Malesian) type with its subtypes is the most abundant one, comprising 36. 1% or 22.4% of all local wild orchid genera or species. Compared with the neighbor provinces, the wild orchid flora in Fujian is closely related to that in Guangdong (shared 48 genera and 97 species) , followed by that in Jiangxi, Zhejiang. The floristic composition of the flora in Fujian is relatively simple, lack of endemic species in this area, and the characteristics of the floristic elements indicate that this is a transitional orchid flora from the tropics to the subtropics, so this area may not be a differentiation center in modern times.
