Cryptostegia madagascariensis

Cryptostegia madagascariensis is a species of flowering plant in the family Apocynaceae.[2] It is commonly known as purple rubber vine, is a woody-perennial vine that is native to western and northern Madagascar. It has also been introduced to several tropical and subtropical regions by man, including Puerto Rico and the Virgin Islands.[3] It is very similar to the rubber vine (C. grandiflora), which is also native to Madagascar.[4] In their area of overlap some hybrids have been observed, which are distinguishable by intermediate flower morphology. In the 1930s a hybrid was also developed for horticultural purposes.[3]
