摘要
对油果樟属(Syndiclis Hook.f.)及其近缘属琼楠属(Beilschmiedia Nees)、孔药楠属(Sinopora J.Li et al.)、国产土楠属(Endiandra R.Br.)和Potameia的网脉结构进行了观察。结果表明,它们的网脉结构可分为3种类型:A型网格小且小脉无游离末端;B型网格小但有不分枝或简单分枝的游离末端;C型网格粗且网脉末端多分枝。琼楠属网脉结构多样,具有全部3种类型,其余4属均仅有1种类型,油果樟属、孔药楠属以及土楠属均为A型,明显不同于Potameia的C型网脉结构。
Minor venation patterns of Syndiclis,Beilschmiedia,Potameia,Sinopora,and Endiandra were observed.The results showed that their venation patterns could be grouped into three types,the Type A with fine leaf reticulations bearing no free ending of veinlets,the Type B with fine leaf reticulations having free and simple ending of veinlets,and the Type C with coarse leaf reticulations possessing profusely branched ending of veinlets.Beilschmiedia was provided with the most diversified venation including all 3 types while other genera had only one of the 3 types each.Syndiclis,Sinopora,and the Chinese Endiandra shared the Type A venation pattern which was different from Potameia with the Type C venation pattern.
