Argyreia nervosa is a perennial climbing vine native to the Indian subcontinent and introduced to numerous areas worldwide, including Hawaii, Africa, and the Caribbean. Though it can be invasive, it is often prized for its aesthetic value. Common names include Hawaiian baby woodrose, adhoguda अधोगुडा or vidhara विधारा (Sanskrit), elephant creeper and woolly morning glory. The two botanical varieties are A. n. var. nervosa described here, and A. n. var. speciosa, a species used in Ayurvedic medicine, but with little to no psychoactive value.
