Semiarundinaria is a genus of running bamboos in the grass family Poaceae, order Poales, native to the temperate and subtropical woodlands of China and Japan. Plants in this genus are characterized by rhizomatous growth habits, producing tall, erect culms (canes) with cylindrical cross-sections and tufts of lanceolate (lance-shaped) leaves at each node. The genus sits within the large and diverse subfamily Bambusoideae, and its species are distributed across eastern Chinese provinces — including Anhui, Guangdong, Hubei, Jiangsu, Jiangxi, Zhejiang, and Hainan — as well as the Japanese islands of Honshu and Kyushu.
The genus contains roughly seven currently recognized species. Among the most widely known is Semiarundinaria fastuosa (Temple bamboo), a tall and statuesque species native to Honshu that has also been cultivated in China and is widely grown as an ornamental in temperate gardens worldwide. Semiarundinaria yashadake and Semiarundinaria kagamiana are also Japanese endemics (both from Honshu). Several species formerly placed in Semiarundinaria have been transferred to related genera including Acidosasa, Fargesia, Sinobambusa, and Yushania, reflecting ongoing revision of bamboo taxonomy.
Distribution
Semiarundinaria is native to temperate and subtropical woodland habitats in China and Japan. Chinese species are found across the eastern and southern provinces of Anhui, Guangdong, Hubei, Jiangsu, Jiangxi, Zhejiang, and Hainan, while Japanese species occur on the islands of Honshu and Kyushu.
Taxonomy Notes
Several species historically placed within Semiarundinaria have been reclassified into related genera, including Acidosasa, Chimonocalamus, Fargesia, Oligostachyum, Phyllosasa, Sasaella, Sinobambusa, and Yushania, reflecting the extensive taxonomic revision that characterises bamboo systematics. GBIF currently recognises the genus in family Poaceae, order Poales.
