Streptolirion is a genus of climbing monocotyledonous flowering plants in the dayflower family. It consists of a single species, namely Streptolirion volubile. It has a broad distribution in Asia, from China 's western Hubei Province as well as the Russian Far East, Korea and Japan in the northeast, south to Vietnam and west to India . Currently two subspecies are accepted: S. volubile subsp. volubile and S. volubile subsp. khasianum, with the latter being a stronger climber covered with erect brown hairs. Streptolirion can be distinguished from the closely related climber Spatholirion by the former's two-seeded carpels and inflorescences that are all subtended by large involucral bracts.[1] They bear yellow hairs below the anthers, which are believed to increase floral attraction by contrasting with the petals or suggesting additional pollen is present.[2] Despite the large range, an analysis of chromosomes found major differences between Japanese and Indian populations, suggesting that additional species may be yet unrecognized.[3]
