It is threatened by habitat loss. ==Apocynaceae Family== The definition of the Apocynaceae family is ''trees, shrubs, or vines, rarely subshrubs or herbs, with latex or watery juice.'' There are about 155 genera and 2000 species distributed primarily in the tropics and subtropics, and poorly represented in the temperate regions . Of the 44 genera and 145 species present in China, one genus and 38 species are endemic, and nearly 95% of the taxa grow in the southern and southwestern portions of the country. The fruit type is highly diversified in the family, and it is diagnostic of many genera. Some genera produce 1 to 2-celled berries from a flower, while others have mostly fleshy follicles containing deeply indented seeds. More detailed information can be derived from (this ) source. Plants of the Apocynaceae are often poisonous and are rich in alkaloids or glycosides, especially in the seeds and latex.
