Yushania rolloana is a species of temperate woody bamboo in the grass family Poaceae, endemic to the hills of Northeast India.
Description and classification
It was originally described by James Sykes Gamble in 1896 as Arundinaria rolloana from material collected in the Naga Hills (then within Assam) by J. Rollo, the species commemorating its collector.[2][1] Following revisions of the temperate woody bamboos, the epithet was transferred to Sinarundinaria by Chao and Renvoize in 1989, and subsequently to its current placement in Yushania by Tong Pei Yi in 1983, the placement accepted by Plants of the World Online and the Catalogue of Life.[1][3]
Like other members of Yushania, it is a clump-forming bamboo with long-necked rhizomes, diffuse culms and several branches at each node, typically of the understorey in cool, high-rainfall montane forest between about 1,525 and 2,135 m (5,003 and 7,005 ft) (5,000 to 7,000 ft).[2][4]
Habitat and behaviour
The species occurs in the Naga Hills and adjoining ranges of southern Nagaland and northern Manipur, with documented populations in the Dzukou Valley (the type area), the Shirui Hills of Ukhrul district, the Japfü range of Kohima district, and Mount Koubru in Senapati district; Plants of the World Online also reports an outlying record from northern Vietnam.[1][5] Locally it is known as Jipvo in Angami Naga. Y. rolloana is the dominant understorey bamboo of the Dzukou Valley and the principal woody component of its grassland mosaic, where dense thickets can reach 9 m (30 ft) in height. The plant flowers infrequently and asynchronously; a sporadic flowering episode was documented in the Dzukou Valley in 2006 by Bhaumik, Mao and Naithani.[6] Following the recurrent dry-season fires of the upper Dzukou Valley, Y. rolloana recolonises burnt ground rapidly and tends to exclude broadleaf regeneration, contributing to the self-reinforcing fire-and-bamboo cycle described from the valley by Mao and Gogoi (2010).[7]
