井冈寒竹属（Gelidocalamus Wen）是一特产于我国亚热带地区散生竹属。该属系统位置和属内种的划分上一直存在争议，至今尚未进行过系统研究。本项目以井冈寒竹属为研究对象，以形态特征为主，结合叶表皮形态、竹秆维管束、地下茎解剖、分枝形成、细胞学等的研究，并赴产地进行野外考察，观察井冈寒竹属植物的变异式样，采集实验所需的材料，界定井冈寒竹属的范围，对国内主要标本馆馆藏的井冈寒竹属标本进行系统整理，澄清分类和命名上的混乱，完成井冈寒竹属的分类研究。

Gelidocalamus Wen (Bambusoideae) , endemically distributed in the subtropical regions of China, is a genus with monopodial culm.The systematic position and the infrageneric classification of this genus are still controversial. This study aims to a thorough taxonomic research on the genus by means of obtaining morphological characters such as leaf epidermis, branching formation,stalk and stem anatomy, and cytology.Field investigations would be made to get the variation patterns of species ,and experimental meterials would be collected. Thus , the systematic position of the genus would be clear. Research on specimens of the genus stored in main herbaria of China would be carried out to clarify the confusion of classification and nomenclature and to accomplish their taxonomic revision.
