Primulina gemella is a plant in the family Gesneriaceae, native to Vietnam. The species was formerly placed in the genus Chirita . [1]
Primulina gemella grows as a perennial herb, with a rhizome measuring up to 7 centimetres (3 in) long. Its leaves are dark green above, whitish green below and measure up to 5 cm (2 in) long. Mauve flowers grow singly, only the type specimen had an inflorescence. [3]
Primulina gemella is endemic to Vietnam, where it is confined to the islands of Hạ Long Bay, a UNESCO World Heritage Site. [1] In 2000, the species was considered confined to a single island, [3] but by 2012 had been found on numerous islands. [1] Its habitat is on soil-covered limestone rocks. [1]
