摘要
孩儿参Ｐｓｅｕｄｏｓｔｅｌａｒｉａｈｅｔｅｒｏｐｈｙｌａ（Ｍｉｑ．）Ｐａｘ的块根系常用中药太子参。本文报道了野生于南京老山地区的孩儿参其植物形态特征与我国其他地区所产孩儿参差异较大，有些差异已超过了《中国植物志》等重要文献属种记载范围。对老山孩儿参居群变异体进行了形态特征描述，统计了其变异率，并提供了该居群的一些生境资料。本文不仅对研究我国太子参药用资源品系有重要的实用价值，而且对研究植物居群分化和该属种的演化与分类提供科学依据。
The root
tuber of Psuedostellaria heterophylla (Miq.) Pax is called taizishen , which is one of
common used traditional Chinese drugs. This paper reports that some morphological
characters of Pseudostellaria heterophylla (Miq.) Pax growing wild in the Laoshan area of
Nanjing are obviously different from those of the species found in other areas of China. Some
morphological characters of the individuals of the population distributed in Laoshan area are
not conform to the descriptions of the genus and species in Flora of China and other
taxonomic works. It provides that these variable characters in morphology, the probabilities of
the variations in some organs, and the information about the habitat by which the variations
may be influenced. It is of significance to making a deep study of the strains of the Chinese
drug taizishen, and discussing the revolution and classification of Pseudostellaria
heterophylla (Miq.) Pax.
