[3] The genus Barnardia was created by John Lindley in 1826 together with the single species B. scilloides.
[2] The plant forms a genetic complex with two genome types, noted A and B, and diploid, allo-triploid and aneuploid specimens in natural populations.
[4][5] In China (Chinese name:棉棗兒 or 绵枣儿), it can be found in Guangdong, Guangxi, Hebei, Heilongjiang, Henan, Hubei, Hunan, Jiangsu, Jiangxi, Jilin, Liaoning, Nei Mongol, Shanxi, Sichuan and Yunnan.
[6] In Northern Taiwan, the plant occupies habitats under 700 meters high in a small amount.
From July to August, it can be easily spotted on the open hillsides or fields along the roads in Dongyin and Xiyin Island.
