With the 39 species nrDNA ITS sequence from Genbank and by using nrDNA ITS sequence information of our study 31 species, a phylogenetic analysis was carried out on 70 species of Paphiopedilum, and then the results have been analyzed with the results from RAPD molecular marker of 30 species, indicated that, we supported Kirasawa's system proposed in 1982 on Paphiopedilum that this genus can be divided into six subgenera.
基于 ITS 序列的数据对兜兰属70个种的研究,结合 RAPD 对于中国兜兰30个种的研究结果进行分析,支持唐沢耕司(1982)所提出的将兜兰属分为6个亚属的观点,其中产于中国的兜兰属植物可以划分为5个亚属;认为巧花兜兰不能并入海伦兜兰中,最多可以作为其变种处理,或者独立成种,隶属于兜兰亚属的 Paphiopedilum 兜兰组;不支持将文山兜兰并入巨瓣兜兰或者同色兜兰中,可以作为是其变种处理,隶属于 Concoloria 组。

Turkestanica var.tuberculata by the scanning electron microscope was also observed after they were identified by light microscope in the bodies of cattle and sheep. Meanwhile the results of the integumental surface was compared with mat of O.turkestanica by Tang Chongti under electron microscope and analyzed them. By means of observing, comparing and analyzing, It showed that both of O. cheni and O. titrkestanica var.tuberculata were the same species, they might only be of different name with O. turkestanica or subspecies or geographical strain, primarily.

Pathogenicity of 83 Curvularia isolates including 76 isolates from corn and 7 isolates from other hosts were tested in seedling and adult stage of corns. Among these species based on morphology, C. lunata, C. pallescens, C. lunate var. aeria, C. clavata and C. ovoidea could cause the typical Curvularia leaf spot symptom that lesions are grayish spots up to 1mm in diameter appear in the centers and straw-colored or chlorotic halos may surround the lesions.
