橡胶紫茉莉，俗称橡胶藤，是多年生的木本和藤本植物，原产于马达加斯加西南部。这也是一种在澳大利亚北部受关注的野草。 它也被引入到其他大多数热带和亚热带地区。 由于其诱人的花瓣和其乳胶能被制成具商业品质的橡胶，因此得名。 它出现在加勒比地区，印度，毛里求斯，东非，东南亚，拉丁美洲，美国南部，斐济和新喀里多尼亚。

种子会在雨季的第一场雨后发芽，直到雨季开始前，生长得并不迅速。 然而，如果有足够的水，橡胶藤可以在1个月里长到高达5米。 通常在雨季结束后开花，随后结果。 通常能在橡胶藤上同时找到成熟和未成熟的果实。

Cryptostegia grandiflora, commonly known as rubber vine, is a woody-perennial vine that is native to south-west Madagascar. It is also a significant weed in northern Australia, sometimes regarded as the worst weed in all of Australia. It has also been introduced to most other tropical and subtropical regions by man, because of its attractive flowers and the fact that its latex contains commercial quality rubber (hence the name). It is now naturalised in the Caribbean, East Africa, Mauritius, India, Southeast Asia, Indonesia, Latin America, the southern United States, Fiji and New Caledonia.
