The results were as follows:(1) Seeds of 80 species or subspecies could be classified into two groups. Group Ⅰ included the seeds of Gramineae, Cyperaceae, Polygonaceae and Amaranthaceae, and Group Ⅱ included the seeds of Compositae, Euphorbiaceae, Brassicaceae and Umbelliferae.(2) Only FTIRs of the seeds of Brassicaceae were clustered together in the dendrogram,while those of the other families all appeared farraginous.(3) Among FTIRs of the 11 groups of the congeneric species,8 groups were clustered with other genus species, and 6 out of 7 groups of conspecific seeds appeared farraginous in the dendrogram.

结果表明：(1)80种草本植物的种子可以分成两类，第1类由禾本科、莎草科、蓼科和苋科植物的种子组成；第2类由菊科、大戟科、十字花科和伞形科植物的种子组成；(2)聚类图上，只有十字花科植物的种子能较好地与其他科的相区别；(3)在11组同属不同种植物中，有8组植物与亲缘关系不同的其他属的植物混在一起；在7组同种不同亚种或品种植物中，仅有1组植物被聚合在一起。

The circumscription of the Minaceae, phylogenetic relationships of genera and its reative were evaluated using morphology and molecular data of rbcL and trnL-F gene of the chloroplast genome.A total of 4 genera and 19 taxa were examined in this study.And some data of Bryaceae were downloaded from Genebank for this analysis. Phylogenetic trees obtained from neighbour jioning and maximum parsimony methods.

本研究用直接测序法测定了提灯藓科4属19种植物的rbcL和trnL-F基因序列，并从Genebank中下载了该科和真藓科的部分基因序列，采用邻接法和最大简约法分别构建了rbcL和trnL-F两个基因片段的系统树，并结合形态方面的分支分析，探讨了提灯藓科的范畴、科内各属的亲缘关系及与其临近科间的关系。

Strain 117 and 43401 are most closely related to the type strains of Nocardia pseudobrasiliensis and Nocardia nova, sharing 16S rDNA sequence similarities of 98.2% and 98.7%, respectively.

在以16S rDNA序列为基础的系统发育树上，菌株117和43401在诺卡氏菌属的辐射分枝范围内形成单独的两个两枝。
