箬竹属（Indocalamus Nakai）是主产于我国的灌木状散生竹属，约30余种，兼具生态价值和经济价值。本属自建立以来虽历经多次修订，但仍遗留颇多的分类学问题，如许多具有潜在分类学及系统学价值的性状研究不足甚至空白，类群鉴定错误，一些新分类群不能成立，存疑种和问题种的分类地位归属不清，以及近缘种的种间界限不明等。本项目拟在已有研究基础上以箬竹属植物为研究对象，以文献考证、标本研究和野外居群调察为基础，利用形态学、细胞学以及系统发育学等研究手段，对箬竹属植物主要宏观和微观形态性状的变异式样进行深入研究，评估这些性状的分类学价值；重建箬竹属的系统发育框架；澄清分类和命名上的混乱，界定种间界限，最终完成箬竹属的分类修订。本项目的开展不仅有助于箬竹属分类学问题的解决，也为该属植物种质资源的保护、开发与利用提供重要理论参考，加深对温带木本竹子多样性和演化过程的理解。

Indocalamus Nakai (Bambusoideae) is a shrub-like scattered genus with more than 30 species, mainly distributed in China. It has both ecological and economic value. Although the genus has undergone many revisions since its establishment, its current taxonomy is still far from satisfactory. For example, many traits with potential taxonomic and systematic value are insufficiently analyzed or even blank, species misidentification, descriptions of old species as new, unresolved classified status of suspicious and problematic species, and unclearly interspecific boundary of relative species, etc. In this project, on the basis of previous studies, we propose to evaluate the taxonomic and systematic significance of important macro- and micro-morphological characters in Indocalamus by in-depth surveying of their variation, reconstruct the phylogenetic relationship, clarify the confusion of classification and naming, define the interspecific boundaries, and finally fulfill the classification revision of the genus Indocalamus. To this end, we will, by using morphological, cytological and phylogenetic research methods, carry out the critical survey of all relevant literature, carefully specimen examination, and extensive population investigations. We believe that launching of this project will not contribute to the solution of taxonomic problems in Indocalamus, but also provides important reference value to the protection, development and utilization of germplasm resources. This project will also advance our understanding of the diversity and evolution process of temperate woody bamboo.
