It confirms that Trachycarpus nana plant grows principally in Central Yunnan Plateau, with Chuxiong at its heart. The paper also makes a preliminary study of the plant's biological and ecological features and thus paves the way for protection and utilization of this rare and near-extinctive plant.A probe is also made into the causes of the plant's near-extinctiveness,so as to facilitate taking protective measures.
