报道了浙江种子植物1个新记录属——膜稃草属HymenachneP.Beauv.和5个新记录种——长圆楼梯草Elatostema oblongifolium Fu ex W.T.Wang、展穗膜稃草Hymenachne patens L.Liou、刚莠竹Microstegium ciliatum(Trin.)A.Camus、短叶黍Panicum brevifolium L.和中华笔草Pseudopogonatherum contortum(Brongn.)A.Camus var.sinense(Keng ex S.L.Chen)Keng et S.L.Chen,并简述了它们与同属相近类群的主要区别。
In this paper, the variation in fruit shape, size and its seed number were studied, and the correlativity of length and diameter of fruit to seed number for 12 species of \%Rhododendron\% from Zhejiang Province were analyzed. Based on the fruit shape and the ratio of length to diameter, 12 species of \%Rhododendron\% L. Were divided into three types. The seed number varied in different species. \%Rhododendron ovatum\% had the highest seed setting efficiency, followed by the species of Subgen \%Tsutsusi\%. The variation of seed number among the individuals of the same species was more obvious than that of the fruit. There was a significant positive correlation between the seed number in fruits and the length, diameter of fruit in most species. The results showed that fruit morphology might be an important character in systematic studies of \%Rhododendron\% L.
