该文根据采自华东地区的一些刚竹属植物居群中的可靠花枝标本,结合现场调查和形态解剖观察,描述和增补了白哺鸡竹、瓜水竹、谷雨竹、云和哺鸡竹的花序、假小穗和花部形态特征,并提供了显示花枝外貌和花器官主要特征的照片。瓜水竹的花序呈头序,小花较短,应属于水竹组; 而其余3种的花序呈穗状,小花较长,应归隶刚竹组。所有的凭证标本均保存于安徽省广德县林业科学研究所竹类标本室中。 |

Abstract: |
Based on the reliable flowering specimens collected from some populations of Phyllostachys in East China, field investigations and anatomical observations, the morphological characteristics of the inflorescence, pseudospikelet and floret of four species within this genus, Ph. dulcis McClure, Ph. longiciliata G. H. Lai, Ph. purpureociliata G. H. Lai and Ph. yunhoensis S. Y. Chen et C. Y. Yao, were described and supplemented, and the photos of flowering branchlets and inflorescences showing main characteristics were provided. Ph. longiciliate G. H. Lai, with capitate inflorescence and short floret, was indicated to belong to sect. Heterocladae C. P. Wang et G. H. Ye, while the other three species, having spitate inflorescence and long floret, were just right to fall into sect. Phyllostachys. All the vouchers were deposited in Herbarium of Guangde Forestry Institute, Anhui Province(GDFI). |
