N2 - Since the introduction of the new genus Sinocalamus in 1940 which is now dissociated into Bambusa and Dendrocalamus, molecular markers have long been unable to discern members of the Bambusa-Dendrocalamus complex. Rapid concerted evolution governed by high level of transition/transversion at the noncoding DNA regions has limited the ability of internal transcribed spacer (rDNA) and trnL-F intergenic spacer to resolve Bambusa and Dendrocalamus in phylogenetic analysis. Based on scanning electron microscopy (SEM) analysis of Bambusa vulgaris and Dendrocalamus manipureanus pollen development, we provided the evidence that there exists genus specificity in the development and structure of woody bamboo pollen which can serve as a benchmark for allocated new species into the genus Bambusa and Dendrocalamus substantiating molecular data.
