Bamboos have provided a variety of raw materials and products widely used in Lao PDR for centuries. Their diversity often leads to confusion, particularly when discussing local and botanical names. This study aimed to use the morphological procedure to identify some bamboos commonly used in the country. Three study sites (Oudomxay province, the capital city of Vientiane, and Champasak province) representing the Northern, Central, and Southern regions, respectively, were chosen as representatives of the country. Ten species from six genera were found: Bambusa blumeana, B. tulda, B. polymorpha, Dendrocalamus brandisii, D. membranaceus, Gigantochloa albociliata, Indosasa sinica, Schizostachyum sp., S. virgatum, and Thyrsostachys siamensis. Their diagnostic morphological characters provide a potential reference source for the identifi cation of bamboos with regard to their products and botanical names. Their diagnostic morphological characters, uses, and habitats were provided.
