摘要
通过文献追溯以及在世界各大植物数据库中搜索安息香属(Styrax)植物的相关信息,确定了该属在中国的种类数量,总结了该属各个种的形态特征和自然地理分布状况。结果表明:1)能确定的最新记载的安息香属植物应有31种,以小乔木居多,花基本为白色,总状或圆锥花序,花芳香的植物只有8种,花期基本都在春、夏季(3—6月),果期在夏、秋、冬季(5—12月);2)在我国除了1种分布至辽宁,大多数主产于长江流域以南各省区,尤其是中南、西南部分布较多;3)超高海拔上没有分布,一半以上的物种适宜生长在低、中海拔的山地中。
Through consulting literatures and searching the relevant information of Styrax species in major plant databases around the world, we determined the species number of this genus in China, summarized the morphological characteristics and natural geographical distribution of Styrax species.The results showed that:1)There should be 31 species newly recorded, most of which are small-sized trees, with white flowers, racemes or panicles, and only 8 flowers with fragrance.Flowering period is in spring and summer (March-June), fruit period is in summer, autumn and winter (May-December);2)Except for 1 species distributed to Liaoning province, most of them are mainly produced in the provinces and regions south of the Yangtze River Basin, especially in the south-central and southwestern parts;3)There is no distribution at high altitudes, but more than half of the species grow well in low and middle altitude mountains.
