摘要
【目的】了解海桐花属植物在陕西省巴山地区的分布情况。【方法和结果】通过对巴山地区白河县友好村海桐花属植物的采集研究与标本鉴定,发现海桐花属植物的陕西省新分布种——短萼海桐[Pittosporum brevicalyx(Oliv.)Gagnep.]。【结论】海桐花属植物在中国主要分布在秦岭以南的亚热带地区,本次发现将该种的分布区向东北扩展到陕西省巴山地区,丰富了陕西秦巴山区的植物分布记录,为巴山地区物种多样性研究提供研究资料。
[Objective]Investigating the distribution of the genus Pittosporum in the Bashan area of Shaanxi Province.[Methods and Results]Based on the investigation,collection,and study of Pittosporum sp.from Youhao village,Baihe County,new geographic distribution of Pittosporum brevicalyx(Oliv.)Gagnep.was discovered in Shaanxi Province.[Conclusion]Pittosporum sp.is mainly distributed in the subtropical areas of the south of the Qinling Mountains in China.This report expands the distribution of this species from northeast to the Daba Mountains of Shaanxi Province,which enriches the distribution records of plants in Qinling-Daba Mountains,as well as provides basis for the study of species diversity in the Daba Mountains.
