[Research advance in rare and endemic plant Tetraena mongolica Maxim].

In this paper, the research advance in rare and endemic plant Tetraena mongolica Maxim. was summarized from the aspects of morphology, anatomy, palynology, cytology, seed-coat micro-morphology, embryology, physiology, biology, ecology, genetic diversity, chemical constituents, endangered causes, and conservation approaches, and the further research directions were prospected. It was considered that population viability, idioplasm conservation and artificial renewal, molecular biology of ecological adaptability, and assessment of habitat suitability should be the main aspects for the future study of T. mongolica.
