Streptolirion is a genus of flowering plants in the family Commelinaceae. It includes two species native to Asia, ranging from Japan and Manchuria to Indochina and the Himalayas.[1]
- Streptolirion lineare Fukuoka & N.Kurosaki – Japan
- Streptolirion volubile Edgew. – Japan and Manchuria to Indochina and the Himalayas
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.[2] 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.[3]
The genus was first described in 1845 by Michael Pakenham Edgeworth and included a single species, Streptolirion volubile. An analysis of chromosomes found major differences between Japanese and Indian populations, suggesting that an additional species might exist.[4] In 1991 Nobuyuki Fukuoka and Nobuhira Kurosaki designated the Japanese population as a new species, Streptolirion lineare.[5]
