Abstract: A new bamboo cultivar Dendrocalamus rongchengensis 'Hualongdan' was cultivated via further separation and transplanting from the variation of artificially cultivated D. rongchengensis Yi et C. Y. Sia. The key difference between 'Hualongdan' and D. rongchengensis is that there are yellowish-white longitudinal stripes of different size on the stem shoots and basal internode and partial blades of the former one, which has higher ornamental value.
