永瓣藤( Monimopetalum chinense Rehd .) 为湖北省种子植物区系新记录属、种, 是中国二级保护植物。通山县分布的永瓣藤为次生杉、竹、阔混交林内的伴生成分, 群落生活型谱以常绿高位芽植物为主, 种群空间分布格局为集群型。 其生态适应为明显的偏酸性和一定的耐荫性。 永瓣藤种群虽规模小, 但具明显的增长型特征, 有发展潜力。 文中对永瓣藤生物多样性保护提出了具体的建议。
 

Monimopetalum Rehd .is a new recorded genus of spermatophyte flora in Hubei Province, based on that M .chinense Rehd .was firstly discovered in Tongshan county as w ell as a rare and endemic species to China.It is an accom pany ing element in the secondary mixed forests of Cunninghamia lanceolata ( Lamb .) Hook ., Phyllostachys pubescens Mazel ex H. de Lehaie and some broad-leaf species .The evergreen phanerophytes is the main part on the life form. spectrum of their community .The spatial distribution pattern of M .chinense Rehd .population trends to be aggregate and the population has obvious shade-adapted and acidophiolous properties .The survivorship curve and size ( age) structure of this population suggest that it is an increasing type and has obvious developmental potentiality .Finally, some practical proposals about biodiversity conservation of M .chinense Rehd. are illustrated .
