Lush jungle flagship species, woody bamboos (Poaceae–Bambusoideae) are famed for their synchronous flowering as well as the extensive “bamboo forests” some species can form in tropical or temperate environments. In portions of their natural distribution, Bambusoideae members developed various adaptations to seasonality in environmental parameters, such as frost or seasonal drought. A new taxon, Laobambos calcareus, described here, is extremely novel in showing the first documented case of succulence in bamboos, with its ability to seasonally vary the volume of its stem depending on the quantity of water stored. Anatomical studies presented in this paper document this specificity at the cellular level. Though no flowers or fruits are known yet, unique morphological characteristics along with an investigation of its phylogenetic affinities using molecular data show that this new taxon should belong to a new genus herein described.

在老挝喀斯特地区的一个新属中发现了第一个多汁竹子（禾本科，Bambusoideae），具有对季节性干旱的独特适应能力。


茂盛的丛林旗舰物种木本竹（禾本科 - 竹亚科）以其同步开花以及某些物种可以在热带或温带环境中形成的大片“竹林”而闻名。在其自然分布的部分地区，竹亚科成员对环境参数的季节性（例如霜冻或季节性干旱）产生了各种适应。这里描述的一个新分类单元，Laobambos calcareus，在显示第一个有记录的竹子多肉案例方面非常新颖，它能够根据储存的水量季节性地改变其茎的体积。本文提出的解剖学研究在细胞水平上记录了这种特异性。尽管尚不清楚花或果实，但独特的形态特征以及使用分子数据对其系统发育亲和力的研究表明，这种新分类单元应该属于本文描述的新属。
