Flowering of Bambusa vulgaris ' Vittata ' (Poaceae, Bambusoideae, Bambuseae) in Argentina

Flowering in woody bamboos remains an intriguing, infrequent and unpredictable event. Bambusa vulgaris 'Vittata' is a woody bamboo species of Asian origin, which is widely cultivated in Argentina and the world due to its various applications. However, there are no records of the flowering of this entity in its place of origin or in cultivation. The goal of the present work is to report the flowering of a B. vulgaris 'Vittata' specimen, cultivated in Buenos Aires, providing information and images of the event and an illustration of its reproductive structures. New reproductive characters have been found to differentiate the taxon, which are included in a dicotomic key.
