Siraitia grosvenorii

Siraitia grosvenorii, also known as monkfruit, luo han guo (Chinese: 羅漢果; pinyin: luóhàn guǒ), or Swingle fruit, is a herbaceous perennial vine of the gourd family, Cucurbitaceae. It is native to southern China. The plant is cultivated for its fruit extract containing mogrosides. Mogroside extract has been used as a low-calorie sweetener for drinks and in traditional Chinese medicine. One mogroside, mogroside V, creates a sweetness sensation 250 times stronger than sucrose.

The scientific species name honors Gilbert Hovey Grosvenor, who, as president of the National Geographic Society, helped to fund an expedition in the 1930s to find the living plant in China where it was already being cultivated.
